How to Calculate U.S. Import Tariffs (Ad Valorem, Specific, Compound)

Calculating the correct tariff before a shipment arrives is one of the most valuable steps an importer can take. Errors in duty estimation lead to cash flow surprises, post-entry audits, and costly penalties. This guide explains the three main tariff calculation methods used by U.S. Customs and Border Protection (CBP), walks through the stacking of multiple duty programs, and shows how to apply them to real entries.

Why Tariff Calculation Matters in 2026

The U.S. tariff landscape has grown significantly more complex since 2018. A single entry may carry: a base Most Favored Nation (MFN) rate, a Section 232 rate on steel or aluminum content, a Section 301 rate on Chinese-origin goods, a Liberation Day IEEPA rate, and an antidumping (AD) or countervailing duty (CVD) rate from a USITC order. Missing any one of these layers understates landed cost. Working with a tariff consulting firm that models all applicable programs simultaneously reduces this risk.

Step 1: Determine the HTS Classification

Every tariff calculation starts with the correct 10-digit Harmonized Tariff Schedule (HTS) subheading. The classification governs the applicable MFN rate, any special program rates, and eligibility for FTA preferences. Misclassification is the most common cause of duty underpayment or overpayment. CBP issues binding rulings that are legally binding for the specific importer and product and protect against penalty in post-entry audits. Classification follows the six General Rules of Interpretation (GRI) applied in sequence.

Step 2: Establish the Customs Value

All ad valorem and compound tariff calculations use the customs value as their base. The primary method is transaction value under 19 U.S.C. §1401a: the price actually paid or payable, adjusted upward for packing costs paid by the buyer, selling commissions, assists (tooling or materials provided free to the manufacturer), and royalties the buyer must pay as a condition of sale.

When transaction value is not applicable (related-party transactions, barter), CBP applies secondary methods in order: transaction value of identical goods, transaction value of similar goods, deductive value, computed value, and fall-back. Our trade advisory services team regularly assists importers in defending or optimizing their customs valuation methodology.

First Sale Valuation

Under CBP’s First Sale program, importers may use the price paid at the first arm’s-length sale in the distribution chain (the manufacturer’s sale to the middleman) rather than the higher importer-paid price. This lower base reduces the ad valorem duty and also reduces the base on which Section 301, IEEPA, and other percentage-rate programs are calculated, compounding the savings.

The Three Tariff Calculation Methods

Ad Valorem Tariffs

An ad valorem tariff is expressed as a percentage of customs value. It is the most common method in the U.S. HTS. For example, HTS 6203.42.4011 (men’s cotton denim trousers) carries a 16.6% MFN rate.

Formula: Duty = Customs Value x Ad Valorem Rate

A shipment with a $50,000 customs value owes $50,000 x 16.6% = $8,300 in MFN duty. If the goods are of Chinese origin and subject to Section 301 List 3 at 25%, that adds $12,500. Any IEEPA rate stacks further on top.

Specific Tariffs

A specific tariff is charged per unit of measure regardless of value. Examples include crude oil (5.25 cents per barrel) and avocados ($0.047 per kilogram). Specific tariffs become proportionally more burdensome when commodity prices fall.

Formula: Duty = Quantity x Specific Rate

A shipment of 10,000 kilograms of avocados at $0.047/kg owes $470 in MFN duty regardless of market price.

Compound Tariffs

Compound tariffs combine an ad valorem and a specific component, appearing in textile, footwear, and certain agricultural categories. A rubber-soled shoe upper might carry “12.5% + $0.20/pair.” Both components are calculated on the same entry and summed.

Formula: Duty = (Customs Value x Ad Valorem Rate) + (Quantity x Specific Rate)

Stacking Multiple Tariff Programs

A 2026 import entry from China may carry four or more concurrent tariff programs. The calculation follows this sequence:

  1. Determine the MFN rate from the HTS 10-digit subheading.
  2. Check Section 232 applicability: steel (Ch. 72-73, 25%), aluminum (Ch. 76, 10%), copper (Ch. 74, 25%), or autos (Ch. 87 specified headings, 25%).
  3. Check Section 301 applicability: if origin is China, identify the List (1-4A) and applicable rate.
  4. Check IEEPA Liberation Day rate: 10% Annex I for most countries, or the applicable Annex II country rate (145% for China as of mid-2026).
  5. Check AD/CVD orders: search the CBP AD/CVD search tool and ITA Enforcement and Compliance database.
  6. Check FTA preferential rate: USMCA, KORUS, etc. reduce or eliminate the MFN layer only — they do not offset Section 232, 301, or IEEPA.

The Captain tariff tracker automates this multi-program calculation for any HTS code and country of origin combination.

Product: Steel pipe fitting, HTS 7307.93.9000, origin China, customs value $100,000.

Program Rate Duty on $100,000
MFN (ad valorem) 4.3% $4,300
Section 232 (steel articles) 25% $25,000
Section 301 List 3 (China) 25% $25,000
IEEPA Liberation Day (China) 145% $145,000
Total duty 199.3% $199,300

The combined effective rate of 199.3% makes this product economically unimportable from China at most market prices. This type of analysis drives sourcing diversion to alternative countries. For context on current rates by country, see our current U.S. tariff rates by country reference.

Post-Entry Duty Recovery

Importers who overpay duties have recovery options. The duty drawback program allows refund of duties paid on imported goods that are subsequently exported or destroyed. IEEPA-specific mechanisms are addressed in our guide on IEEPA tariff refunds. Protests filed within 90 days of CBP liquidation can contest the classification, value, or applicable rate.

Frequently Asked Questions

What is an ad valorem tariff?

An ad valorem tariff is a duty expressed as a percentage of the customs value of imported goods. It is the most common tariff type in the U.S. HTS. The duty equals the customs value multiplied by the applicable rate.

What is the difference between a specific and compound tariff?

A specific tariff is charged per unit of measure (for example, $0.05 per kilogram) regardless of value. A compound tariff combines a percentage component and a per-unit component; both are calculated and summed for the total duty owed.

How is customs value determined?

The primary method is transaction value: the price paid or payable for the goods when sold for export to the United States, adjusted for additions such as packing, assists, royalties, and proceeds of resale under 19 U.S.C. §1401a.

Can multiple tariff programs apply to the same shipment?

Yes. A single entry from China may carry an MFN rate, Section 232, Section 301, IEEPA Liberation Day, and AD/CVD rates simultaneously. All applicable rates are calculated on the same customs value and summed; there is no offsetting between programs.

What is First Sale valuation and how does it reduce duties?

First Sale allows an importer to declare the factory sale price (the first arm’s-length sale in the chain) as the customs value rather than the higher importer-paid price. Because most tariff programs are ad valorem percentages calculated on customs value, a lower value base reduces the total duty owed across all stacked programs.

What is a binding ruling and why do I need one?

A CBP binding ruling is a written decision committing CBP to a specific HTS classification for a particular importer and product. It provides certainty before importation and protects against penalty in post-entry audits. Submit requests through the CBP Ruling Request program with full product description and supporting technical documentation.

How do I challenge a CBP duty assessment?

File a protest with CBP within 180 days of the date of liquidation (finalization) of the entry. The protest can contest the classification, value, applicable rate, or any other matter affecting the amount of duty. If CBP denies the protest, appeal to the Court of International Trade.

Current U.S. Tariff Rates by Country (Live Table)

Tracking effective U.S. import tariff rates by country of origin is one of the most operationally demanding tasks for compliance teams in 2026. The base Most Favored Nation (MFN) rate, Section 232 and Section 301 programs, the Liberation Day IEEPA framework, and active antidumping and countervailing duty (AD/CVD) orders all contribute to a rapidly shifting composite rate. This page explains how the rate structure works and provides a country-by-country summary of key programs and current exposure levels.

How U.S. Tariff Rates Work by Country of Origin

U.S. tariff rates are product-specific first and country-specific second. The same HTS subheading may carry a zero rate under a free trade agreement for one country, a 25% Section 301 rate for Chinese-origin goods, and a 10% Liberation Day baseline for most others. The composite effective tariff rate is the sum of all applicable programs, not a choice between them.

Layer 1: MFN Base Rate

The MFN base rate from the Harmonized Tariff Schedule applies to all WTO members and other countries on the U.S. normal trade relations list. Rates range from zero for many technology products and raw materials to over 30% for certain apparel, footwear, and sugar products. This is the starting point for any tariff calculation. The authoritative published schedule is maintained by the U.S. International Trade Commission (USITC) at the HTS Online database.

Layer 2: Preferential (FTA) Rates

Goods qualifying for originating status under a U.S. free trade agreement receive a reduced or zero MFN rate. Active U.S. FTAs include USMCA (Canada and Mexico), KORUS (South Korea), the U.S.-Japan Trade Agreement 2020, and agreements with Singapore, Australia, Chile, Colombia, Peru, and several others. Preferential rates reduce only the MFN component; they do not offset Section 232, Section 301, or IEEPA tariffs, which are imposed under separate statutes.

Layer 3: Remedial Tariffs (232, 301, IEEPA)

These programs represent the most significant tariff exposure for most importers in 2026:

  • Section 232: 25% on steel articles (Chapters 72-73), 10% on aluminum (Chapter 76), 25% on copper (Chapter 74), and 25% on autos and auto parts (Chapter 87 specified headings). Country-specific TRQ arrangements exempt quota volumes for certain allies.
  • Section 301: Applies only to Chinese-origin goods at rates from 7.5% to 25%+ depending on the applicable List.
  • IEEPA Liberation Day: 10% baseline (Annex I) on imports from nearly all countries, with country-specific rates (Annex II) for major deficit partners. China currently faces 145% under IEEPA.

Layer 4: AD/CVD Orders

Antidumping and countervailing duty orders are product and country-specific and can carry rates well above 100%. Active orders cover a wide range of Chinese, Vietnamese, Indian, and other origin goods in solar, steel, seafood, and other categories. Rates vary by manufacturer within the same country. The CBP AD/CVD search tool and the ITA Enforcement and Compliance database are the authoritative sources for current cash deposit rates.

The summary below reflects the primary tariff programs as of mid-2026. For product-specific exact rates, use the Captain tariff tracker.

China

China faces the most complex tariff stack available. MFN rates apply at the product level. Section 301 rates of 7.5% to 25%+ apply across virtually all categories. The IEEPA Liberation Day rate on Chinese goods reached 145% by May 2025. Combined effective rates on many manufactured goods exceed 150%, making Chinese sourcing economically prohibitive for large product categories. Understanding Section 301 tariffs on China is foundational to any China supply chain analysis. The Liberation Day tariff framework adds further layers that interact with Section 301.

Our complete guide to U.S. tariffs on China covers every statutory authority, the current rate stack, and step-by-step mitigation strategies.

Canada

Canada benefits from USMCA zero rates on most qualifying originating goods. Section 232 TRQs apply to steel and aluminum: volumes within the annual quota face zero Section 232, while above-quota volumes face 25%. The Liberation Day 10% baseline applies to non-USMCA-qualifying Canadian goods. Transshipment enforcement has increased scrutiny of Canadian entries containing Chinese-origin inputs that do not meet USMCA rules of origin.

See the U.S. tariffs on Canada guide for a full breakdown of USMCA eligibility, Section 232 TRQ mechanics, and the Liberation Day framework.

Mexico

Mexico mirrors Canada under USMCA for qualifying goods. Section 232 TRQs apply to steel and aluminum similarly. A significant enforcement priority in 2025-2026 has been Chinese-origin goods transshipped through Mexico without undergoing substantial transformation, which are subject to the full Chinese tariff stack regardless of the Mexican point of export.

Our U.S. tariffs on Mexico guide details USMCA qualification requirements, the executive orders on fentanyl, and nearshoring considerations.

European Union

EU goods were assigned a 20% Liberation Day Annex II rate, paused at 10% as of April 9, 2025. Section 232 steel and aluminum tariffs apply at 25% on volumes outside TRQs. No FTA between the U.S. and EU currently exists (the TTIP negotiations concluded without agreement). The rate trajectory for EU goods depends on bilateral trade deal progress throughout 2026.

The U.S. tariffs on EU guide covers Section 232 steel and aluminum, the Liberation Day rate trajectory, and sector-by-sector exposure for European exporters.

Vietnam

Vietnam was assigned the highest Annex II rate of any major trading partner: 46%, paused at 10% during negotiations. Active AD/CVD orders cover Vietnamese solar panels, steel, catfish, and shrimp. Vietnam has been the primary China-plus-one beneficiary since 2018; the high Annex II rate and active AD/CVD coverage mean that alternative sourcing to Vietnam requires careful tariff modeling before commitment. See our analysis of the China-Plus-One strategy for how Vietnam compares with other alternatives.

Our U.S. tariffs on Vietnam guide covers the 46% reciprocal rate, active AD/CVD orders, and circumvention risk for importers sourcing through Vietnamese factories.

India

India was assigned a 26% Annex II rate under Liberation Day, paused at 10%. A preliminary bilateral deal framework announced in early 2026 may reduce this rate. Section 232 applies to Indian steel and aluminum. India has no FTA with the United States. Active AD/CVD orders cover certain Indian steel and chemical products.

The U.S. tariffs on India guide provides a full breakdown of the 26% Annex II rate, the preliminary bilateral framework, and Section 232 exposure for Indian steel and aluminum.

Japan

Japan was assigned a 24% Annex II rate, paused at 10%. The U.S.-Japan Trade Agreement 2020 provides preferential rates on certain agricultural and industrial goods at the MFN layer but does not offset Section 232 or IEEPA. Section 232 TRQs apply to Japanese steel under the 2022 arrangement.

Our U.S. tariffs on Japan guide covers the 24% Annex II rate, U.S.-Japan Trade Agreement 2020 preferences, and Section 232 steel TRQ mechanics.

South Korea

South Korea faces a 25% Annex II rate (paused at 10%) plus Section 232 for steel quantities above the KORUS TRQ. The KORUS FTA provides MFN-layer preferences on many manufactured goods. South Korean auto exports to the U.S. face the new Section 232 auto tariff for non-USMCA qualifying content.

The U.S. tariffs on South Korea guide details KORUS FTA eligibility, Section 232 steel TRQ mechanics, and auto tariff exposure for Korean-assembled vehicles.

Taiwan

Taiwan was assigned a 32% Annex II rate under Liberation Day, paused at 10% during negotiations. Taiwan is the dominant global source for advanced semiconductors. A Section 232 investigation targeting semiconductor imports directly raises the stakes for Taiwanese chipmakers and their U.S. buyers. No U.S.-Taiwan FTA exists. The U.S. tariffs on Taiwan guide covers the semiconductor Section 232 risk, the reciprocal rate structure, and compliance considerations for tech importers.

Brazil

Brazil was assigned a 10% Annex II rate under Liberation Day. Section 232 steel TRQs apply to Brazilian flat-rolled and semi-finished steel exports within historical quota volumes; above-quota volumes face 25%. Brazil also faces Section 201 safeguard tariffs on certain steel and solar products. Active AD/CVD orders cover Brazilian citric acid and certain steel products. See the U.S. tariffs on Brazil guide for a full breakdown of the Section 232 TRQ mechanics and GSP eligibility status.

Thailand

Thailand was assigned a 36% Annex II rate under Liberation Day, paused at 10% during negotiations. Thailand relies heavily on exports of hard disk drives, rubber, seafood, and automotive parts to the U.S. market. Partial GSP eligibility has historically reduced MFN rates on certain Thai goods, though the current GSP status requires verification. Our U.S. tariffs on Thailand guide covers the reciprocal rate framework, GSP eligibility categories, and affected HTS sectors.

Indonesia

Indonesia was assigned a 32% Annex II rate, paused at 10%. Indonesia’s primary U.S. exports include apparel, footwear, rubber, and seafood. GSP partial eligibility applies to select categories. Active AD/CVD orders cover certain Indonesian steel and biodiesel products. The U.S. tariffs on Indonesia guide covers the full reciprocal rate structure, GSP eligibility, and sector-specific tariff exposure.

Malaysia

Malaysia was assigned a 24% Annex II rate, paused at 10%. Malaysia is a major semiconductor packaging and assembly hub, particularly in Penang. A Section 232 investigation targeting semiconductor imports creates direct exposure for Malaysian chip packaging facilities. No U.S.-Malaysia FTA is in force. Our U.S. tariffs on Malaysia guide covers the semiconductor Section 232 risk, the reciprocal rate, and supply chain implications for tech importers.

Procurement teams increasingly model tariff exposure as a core component of total cost of ownership alongside unit cost, lead time, quality, and logistics. At combined effective rates above 50%, the economics of alternative sourcing often become compelling even when factory prices in alternative countries are 20-30% higher.

Our trade advisory services team builds total cost models that incorporate all tariff layers, logistics differentials, FTZ and First Sale optimization, and drawback potential to produce fully loaded landed cost comparisons across sourcing scenarios. For importers currently weighing China versus Vietnam versus India alternatives, a tariff consulting engagement typically covers current effective rates, expected rate trajectory, qualifying rules of origin, and AD/CVD risk in each candidate country.

Frequently Asked Questions

Where can I find the current U.S. tariff rate for my product?

The USITC HTS Online gives the published MFN rate. CBP’s ACE portal shows the combined duty for an entry. The Federal Register is authoritative for IEEPA, Section 232, and Section 301 program rates. The ITA database covers AD/CVD. Our Captain tariff tracker aggregates all of these for quick product-level lookup.

What is the effective tariff rate on Chinese imports in 2026?

The effective rate varies by product but typically comprises MFN (product-specific), Section 301 (7.5% to 25%+), and IEEPA Liberation Day (145% as of mid-2026), plus any AD/CVD order rates. Combined effective rates on many manufactured goods from China exceed 150%.

Does USMCA eliminate all tariffs from Canada and Mexico?

USMCA eliminates MFN duties on qualifying originating goods but does not eliminate Section 232 steel and aluminum tariffs (which apply under a separate TRQ structure) or Liberation Day IEEPA tariffs on non-qualifying goods. Chinese-origin content transshipped without substantial transformation does not qualify for USMCA treatment.

Why does Vietnam have a 46% tariff rate?

Vietnam was assigned a 46% reciprocal rate under Liberation Day Annex II based on USTR’s trade deficit formula. This rate is paused at 10% during bilateral negotiations, but the 46% remains the scheduled rate if negotiations fail. The high rate reflects the large bilateral trade deficit the U.S. runs with Vietnam.

Do FTA preferential rates offset Section 232 tariffs?

No. FTA rates reduce or eliminate only the MFN component. Section 232 is imposed under the Trade Expansion Act of 1962, a separate legal authority. A Canadian steel product that is zero-rated under USMCA for its MFN duty still owes Section 232 on volumes above the TRQ threshold.

How often do U.S. tariff rates change?

MFN rates change rarely. Remedial tariff rates change frequently: Section 232 exclusions are updated quarterly, Section 301 exclusions have expiration dates, and IEEPA rates have been modified multiple times throughout 2025-2026. AD/CVD rates change at each annual review. Daily monitoring of Federal Register and CBP publications is necessary for import programs with ongoing exposure.

Section 232 Tariffs: Steel, Aluminum, Copper and Auto Duties Explained

Section 232 tariffs are import duties authorized by the Trade Expansion Act of 1962 when the U.S. Department of Commerce determines that imports threaten national security. The program covers steel, aluminum, copper, and autos. Rates run from 25% to 50% depending on the product and country of origin. For U.S. importers, these duties stack on top of Section 301 and Reciprocal Tariff Act rates, compounding landed cost pressure across multiple supply chains.

Under 19 USC §1862, the president can impose duties or quotas after a DOC investigation concludes that import volumes endanger domestic industrial capacity. The Bureau of Industry and Security (BIS) within the DOC administers the program and publishes all actions in the Federal Register.

Which Products Fall Under Section 232 in 2026

Section 232 coverage has expanded significantly since 2018. The four active product categories are below.

Steel and Steel Derivatives (HTS Chapter 72, 73)

A 25% tariff on steel mill products took effect March 23, 2018 (Proclamation 9705). HTS Chapters 72 and 73 cover hot-rolled coil, cold-rolled sheet, structural beams, pipes, tubes, and fabricated steel products. Several countries negotiated quota agreements in exchange for tariff exemptions. Those exemptions have been narrowed or eliminated for most trading partners in 2026. Work the steel and aluminum tariffs guide for current country-specific rates.

Aluminum and Aluminum Derivatives (HTS Chapter 76)

Aluminum entered the Section 232 program at 10% in March 2018 (Proclamation 9704). The rate was raised to 25% for most countries in 2026. HTS Chapter 76 covers primary aluminum, alloyed aluminum, plates, sheets, foil, tubes, and pipes. Derivative products (parts made primarily from aluminum) are also covered.

Copper and Copper-Intensive Products (HTS Chapter 74)

A 50% Section 232 tariff on copper was announced in 2026. HTS Chapter 74 covers refined copper, copper alloys, wire, rods, plates, and tubes. This is the highest Section 232 rate applied to any commodity. Importers sourcing copper wire, bus bars, or heat exchangers should recalculate landed costs immediately. Review the full copper tariff breakdown for HTS-level detail.

Autos and Auto Parts (HTS Chapter 87)

A 25% tariff on passenger vehicles and auto parts took effect in 2026. HTS Chapter 87 covers passenger cars, light trucks, and a defined list of auto parts. The parts list includes engines, transmissions, body stampings, axles, and suspension components. Vehicles qualifying under USMCA are subject to different treatment depending on regional content percentages.

Current Section 232 Rates and Duty Stacking

The table below shows the active Section 232 rates as of 2026:

  • Steel: 25% (most countries); higher for certain steel derivative products
  • Aluminum: 25% (most countries)
  • Copper: 50%
  • Autos and auto parts: 25%

Section 232 duties are additive. An importer bringing in Chinese steel pays the Section 232 steel duty (25%) plus Section 301 list duties (if the HTS code appears on a Section 301 list) plus the Reciprocal Tariff Act rate (145% for China). The combined rate can exceed 170% on affected steel products. Use the Captain tariff tracker to calculate stacked duties by HTS code and country of origin before each purchase order.

How the Section 232 Exclusion Process Works

BIS operates the Section 232 exclusion portal under 15 CFR Part 705. Importers, manufacturers, and other interested parties can request product-specific exclusions. An approved exclusion lets a named company import a defined product at zero Section 232 duty.

Eligibility Criteria

To qualify, the requester must show that the product is not produced in the U.S. in sufficient quantities, not produced in adequate quality, or not available in a timely manner from domestic sources. The request must identify the specific HTS subheading and describe the product in technical terms that match the actual import.

BIS Exclusion Portal Walkthrough

File the exclusion request through the BIS Section 232 exclusion portal. The submission requires a company profile, product description, quantity requested, domestic supplier objection process, and supporting documentation. After submission, domestic steel or aluminum producers can file objections within 30 days. BIS adjudicates the record and issues a determination published in the Federal Register. The USITC provides data support for BIS on many requests.

Common Rejection Reasons

BIS rejects exclusion requests when domestic availability is not adequately disproven, when the product description does not precisely match the HTS subheading, or when a domestic producer successfully objects with capacity evidence. Requests without specific mill certifications or technical specs are also frequently denied.

These three tariff authorities overlap but have different legal bases and triggers.

  • Section 232: National security threat to domestic industry. No expiration. Applies globally with country-specific carveouts. BIS administers.
  • Section 301: Unfair trade practices by a foreign government. China-specific in current application. USTR administers. See the full Section 301 tariffs on China analysis for list-by-list breakdowns.
  • Section 122: Balance-of-payments emergency. Maximum 15% rate. Maximum 150-day duration. Has not been used as a comprehensive surcharge in modern trade history.

The Reciprocal Tariff Act adds a fourth layer based on bilateral trade deficits. All four programs can apply simultaneously to a single shipment. The Trump tariff tracker shows live stacked rates for your HTS codes across all four authorities.

How Importers Reduce Section 232 Exposure

Three mechanisms reduce or defer Section 232 duties without changing the HTS classification:

  1. Foreign-Trade Zone (FTZ): Goods admitted to an FTZ before a rate proclamation takes effect enter at the pre-proclamation rate. FTZs also eliminate duties on goods re-exported without entering U.S. commerce.
  2. Customs bonded warehouse: Duties are deferred until withdrawal for consumption. If a rate drops or an exclusion is granted, the importer can withdraw at the lower rate.
  3. Section 232 exclusion: Company-specific exclusions eliminate the duty entirely for approved products and quantities.

A tariff consulting firm can identify which mechanism applies to your product and model the savings against setup costs. The trade advisory services team runs the landed cost comparison across all three options before recommending a strategy.

Frequently Asked Questions

Are Section 232 tariffs still active in 2026?

Yes. Section 232 tariffs on steel and aluminum remain fully active in 2026. Copper and auto parts were added in 2026. No sunset date applies. Congress can modify the program through legislation, but the executive orders implementing current rates remain in force.

What is the current Section 232 tariff rate on steel?

The base rate is 25% for most countries. Some country-specific agreements set different rates or quotas. Check the Federal Register for the most recent proclamation applying to your supplier’s country of origin.

Can I file a Section 232 exclusion request as an importer?

Yes. Importers, manufacturers, and purchasers of steel and aluminum products can file exclusion requests through the BIS Section 232 exclusion portal. The process requires product-specific documentation and a showing that domestic supply is insufficient.

Do Section 232 tariffs stack with Section 301 China tariffs?

Yes. If a Chinese steel product appears on a Section 301 list, both the Section 232 rate and the Section 301 rate apply. The Reciprocal Tariff Act rate also stacks. All three are cumulative on top of the base HTSUS Column 1 duty.

Is there a Section 232 refund mechanism?

There is no standalone refund program for Section 232 duties. However, Section 232 duties are generally eligible for duty drawback under 19 USC §1313, meaning importers who re-export finished goods can recover up to 99% of duties paid on the imported inputs.

What HTS codes are covered by Section 232 copper?

Section 232 copper covers HTS Chapter 74, which includes refined copper (7401-7403), copper alloys (7403-7407), copper plates, sheets, strip, and foil (7409-7410), copper tubes and pipes (7411), and copper wire (7408). Check the specific proclamation for the exact HTS subheadings covered.

How long does a Section 232 exclusion request take?

BIS targets 90 days for a determination, but complex requests with objections from domestic producers can take 6-12 months. Plan procurement timelines accordingly. An approved exclusion is retroactive to the date of filing, so duties paid during the review period can be recovered.

Section 232 exposure is predictable when you map it by HTS code before placing orders. The tariff consulting firm team runs HTS-level Section 232 analysis as part of every import cost review. The trade advisory services team then models exclusion eligibility, drawback recovery, and FTZ deferral to find the lowest landed cost path.

Section 232 vs 301 vs 122: Which Tariff Authority Applies to Your Imports?

Three tariff authorities — Section 232, Section 301, and Section 122 — form the backbone of the remedial tariff environment U.S. importers face in 2026. Each derives from a different statute, targets different policy objectives, and covers different products and countries. Understanding which authority applies to a given import is the first step in any tariff analysis and the foundation of any mitigation strategy.

The Key Distinction Before Diving In

Section 232 is a national security tool. Section 301 is an unfair trade practices tool. Section 122 is a balance-of-payments emergency tool. They can and do coexist on the same customs entry — a Chinese steel part might simultaneously owe duties under all three relevant frameworks. Starting with this distinction prevents the common mistake of treating them as alternatives.

Section 232 of the Trade Expansion Act of 1962 authorizes the President to impose import restrictions after the Secretary of Commerce and the Bureau of Industry and Security (BIS) of the U.S. Department of Commerce (DOC) investigate and determine that an article is being imported in quantities or under circumstances that threaten to impair national security. BIS evaluates factors including domestic production capacity, the defense industrial base’s requirements, and the impact of imports on those requirements.

Current Section 232 Programs

  • Steel articles (HTS Chapters 72-73): 25% ad valorem from most countries. Country-specific tariff-rate quotas (TRQs) exist for Canada, Mexico, the EU, Japan, and others, allowing quota volumes at zero or reduced rates.
  • Aluminum articles (HTS Chapter 76): 10% from most countries, with TRQ arrangements for certain allies.
  • Copper and copper articles (HTS Chapter 74): 25%, announced in 2025 as part of the expanding national security review of critical minerals.
  • Autos and auto parts (HTS Chapter 87, specified subheadings): 25%, with a phase-in for USMCA-qualifying content.

Section 232 does not inherently target a single country. The current programs apply globally with country-specific exceptions negotiated as TRQs. The Federal Register publishes quarterly TRQ fill-rate data. Product exclusions are available for specific HTS subheadings where the product is not available in sufficient quantity, quality, or timeliness from domestic producers. Approved general approved exclusions (GAEs) are available for use by any importer. Working with a tariff consulting firm to identify applicable GAEs or pursue new exclusion requests often delivers measurable duty savings.

Section 232 Process

A Section 232 action requires a formal Commerce Department investigation, a report finding a national security threat, and a Presidential proclamation implementing the remedy. The process is more deliberate than IEEPA because it requires the BIS investigation step. Once proclaimed, Section 232 duties are indefinite.

Section 301: Unfair Trade Practice Tariffs

Section 301 of the Trade Act of 1974 authorizes the Office of the U.S. Trade Representative (USTR) to investigate foreign government acts, policies, and practices that are unreasonable or discriminatory and burden or restrict U.S. commerce, and to take appropriate retaliatory action. Unlike Section 232, Section 301 targets a specific country and a specific set of practices.

Current Section 301 Program: China

The active Section 301 action targets China based on USTR’s 2018 investigation finding that China engages in unfair practices related to technology transfer, intellectual property, and innovation. The tariffs are organized by “List”:

  • Lists 1 and 2: 25% on approximately $50 billion in goods (industrial equipment, aerospace components)
  • List 3: 25% (raised from 10% in 2019) on approximately $200 billion in goods (consumer electronics, furniture, machinery)
  • List 4A: 7.5% on approximately $120 billion in goods (consumer electronics, apparel, footwear)

USTR’s 2024 four-year statutory review resulted in targeted rate increases on strategic categories: electric vehicles (100%), solar cells (50%), lithium batteries (25%), ship-to-shore cranes (25%), and medical gloves (25%).

Section 301 and the Liberation Day IEEPA Stack

Beginning April 2025, the IEEPA Liberation Day rate stacked additively on Section 301 for Chinese goods. For a product subject to 25% Section 301 and 145% IEEPA, the combined remedial tariff is 170%, on top of the applicable MFN rate. Understanding Liberation Day tariffs is therefore inseparable from Section 301 analysis for Chinese-origin goods. See our review of Section 301 tariffs on China for the full product list and rate history.

Section 301 Exclusion Process

USTR has operated rolling exclusion request processes for Section 301. An exclusion removes the tariff for a specific HTS subheading and typically expires after one year. Exclusion requests must demonstrate that the product is not reasonably available from non-Chinese sources or that the tariff causes severe economic harm. The USITC publishes analysis supporting exclusion determinations.

Section 122: Balance-of-Payments Tariffs

Section 122 of the Trade Act of 1974 grants the President authority to impose a temporary import surcharge when the United States is experiencing “large and serious” balance-of-payments deficits or a significant depreciation in the exchange value of the dollar. This authority is less well-known because it has not been formally invoked since 1971 (under President Nixon as part of the Smithsonian Agreement framework). It received renewed attention in 2025 as a possible alternative legal basis for the Liberation Day tariff framework.

Key Constraints of Section 122

  • Rate cap: Section 122 limits the surcharge to a maximum of 15%.
  • Duration cap: The surcharge can last no more than 150 days without Congressional action.
  • Universal application: Section 122 does not allow country-specific differentiation; it applies to all imports equally.

These constraints explain why the Liberation Day framework used IEEPA rather than Section 122. IEEPA has no statutory rate cap, no time limit once an emergency is declared, and allows country-specific rate differentiation — all essential for the Annex II country-specific reciprocal rate structure with rates exceeding 100% for China. The USITC has published comparative analysis of IEEPA and Section 122 scope and limitations for interested parties.

Mitigation Strategies by Authority

Each tariff authority has distinct mitigation pathways:

  • Section 232: Product exclusion applications to BIS, reclassification to a non-covered subheading, sourcing from TRQ-exempt country volumes, FTZ use for melted-and-poured origin tracing.
  • Section 301: USTR exclusion requests for specific HTS subheadings, First Sale valuation to reduce the dutiable base, drawback on subsequent exports, sourcing diversification to non-China origins.
  • IEEPA (Liberation Day): Annex III product-level carve-out monitoring, bilateral deal memo tracking for country rate reductions, FTZ deferral pending exclusion rulings or court decisions.

Frequently Asked Questions

What is the difference between Section 232 and Section 301 tariffs?

Section 232 is a national security tariff under the Trade Expansion Act of 1962, currently applied globally to steel (25%), aluminum (10%), copper (25%), and autos (25%). Section 301 is an unfair trade practices tariff under the Trade Act of 1974, currently applied only to Chinese-origin goods at rates from 7.5% to 25%+. Both can apply to the same entry from China.

Does Section 301 apply to countries other than China?

No active Section 301 orders apply to countries other than China as of mid-2026. While Section 301 can be used against any country, the current action targets China specifically in response to USTR’s 2018 investigation findings on technology transfer and IP practices.

What is Section 122 and why is it not used?

Section 122 authorizes a temporary up-to-15% universal import surcharge for up to 150 days to address balance-of-payments deficits. It has not been formally invoked since 1971. The 15% rate cap and 150-day time limit make it unsuitable for the Liberation Day framework, which required country-specific rates exceeding 100% on an indefinite basis — capabilities IEEPA provides but Section 122 does not.

Can Section 232 and Section 301 both apply to the same Chinese steel shipment?

Yes. A Chinese steel fitting, for example, carries Section 232 (25%), Section 301 (25%), and IEEPA Liberation Day (145%) simultaneously. All applicable rates are calculated on the same customs value and summed. The combined effective rate on some Chinese steel products exceeds 200%.

How do I get a Section 232 product exclusion?

Submit an exclusion request to BIS through the Section 232 exclusion portal. The request must demonstrate that the product is not produced in the U.S. in sufficient quantity, quality, or timeliness. Approved exclusions become General Approved Exclusions (GAEs) available for any importer to use. Monitor the Federal Register for newly published GAEs that may cover your product.

Are Section 301 tariffs permanent?

Section 301 tariffs are indefinite but subject to mandatory four-year statutory review by USTR. Reviews can raise rates, reduce them, add product categories, or terminate the action. The 2024 review raised rates on strategic goods. The next review cycle is expected in 2028.
