Four Tariff Authorities Driving Import Costs in 2026
Trump-era tariffs do not come from one law. Four separate legal authorities can stack on a single shipment. Which law applies to your HTS code determines whether your effective rate is 10% or 195%+. Understanding each authority — and how courts have challenged them — is essential for accurate landed cost modeling.
Reciprocal Tariff Act (IEEPA)
The Reciprocal Tariff Act took effect April 2, 2026, under IEEPA authority. It imposes differentiated rates based on bilateral trade deficits. China pays 145%. Most countries pay 10%–46% depending on surplus size. Canada and Mexico are excluded. This is the broadest disruption for general importers in 2026.
Note on legal status: In February 2026, the Supreme Court ruled 6-3 that IEEPA does not independently authorize tariff imposition, invalidating approximately 75% of the administration’s original tariff authority. The administration responded by expanding its use of Section 301 and Section 232, where statutory authority is better established. Importers should monitor Federal Register updates, as rate changes stemming from the reconstruction of tariff authority continue to take effect.
Section 232 Tariffs (National Security)
Section 232 tariffs cover steel (25%), aluminum (25%), copper (50%), and autos and auto parts (25%). They apply globally and stack on top of Reciprocal Tariff Act rates. A Chinese steel shipment carries Section 232 (25%), Section 301 (25%), and Reciprocal Tariff Act (145%) duties simultaneously. Combined effective rate: over 195% above the base HTSUS duty. Section 232 has no statutory expiration date, making it the most durable of the four authorities.
Section 301 Tariffs (China Unfair Trade)
Section 301 tariffs are China-specific. USTR imposed them across four lists covering $370 billion in annual Chinese imports. List 3 carries 25%. List 4A carries 7.5%. The 2026 Reciprocal Tariff Act stacks on top, bringing most Chinese goods to 145%+ total effective rate.
Post-IEEPA expansion: Following the Supreme Court ruling, the administration launched two new Section 301 investigations — one targeting manufacturing overcapacity in 16 countries covering over 75% of U.S. imports, and another targeting forced-labor practices across roughly 60 economies covering nearly all U.S. import volume. Section 301 now functions as the primary legal vehicle for broad tariff authority going forward.
Section 122 Tariffs (Balance of Payments)
Section 122 allows a 15% surcharge on all dutiable imports when the U.S. faces a large balance-of-payments deficit. Maximum duration is 150 days. The Court of International Trade ruled against the Section 122 across-the-board 10% import surcharge in May 2026 — the decision is under appeal, but tariffs continue to be collected during the appeal period. The authority expires July 24, 2026 unless Congress acts to extend it. Unlike Section 301, a Section 122 surcharge hits every country at once, including Mexico, Canada, and the EU.
How the 2026 Legal Challenges Reshaped the Tariff Map
For importers, the legal battles over tariff authority matter operationally — not just politically. When a court rules against an authority and the administration shifts to a different legal vehicle, the applicable rates, product coverage, and country scope all change. Tracking those shifts in real time is what separates reactive importers from those who can plan ahead.
What the IEEPA Ruling Changed for Importers
Before the February 2026 Supreme Court ruling, IEEPA was the legal foundation for the broad “Liberation Day” reciprocal rate structure. Post-ruling, the administration reconstructed tariff authority through expanded Section 301 investigations — a slower process with statutory timelines (12-month determination periods), but one with a stronger legal footing. For importers, the practical effect is that rates on specific product categories and countries may shift as new Section 301 lists are finalized and existing IEEPA-based rates are either codified under new authority or allowed to lapse.
Section 301 as the Primary Tool Going Forward
Section 301 is now doing more work than at any point in its 50-year history. The two new investigations launched in 2026 — on overcapacity and forced labor — cover a scope of trade previously only reachable through IEEPA. The distinction for importers: Section 301 tariffs require a formal investigation and determination process, which means rate changes come with more advance notice than executive-order-based IEEPA adjustments. However, Section 301 tariffs also expire after four years unless actively extended, creating a renewal cycle that adds medium-term uncertainty.
Three Strategic Roles Tariffs Play in U.S. Trade Policy
Understanding why tariffs are being imposed — not just what rates apply — helps importers anticipate which rates are durable and which are bargaining chips. The current administration deploys tariffs in three distinct modes:
- Negotiation leverage: Tariffs imposed to bring trading partners to the table. These are most likely to be reduced or paused when bilateral talks progress — as seen in the 90-day pause offered to countries that agreed to negotiate. Watch for executive orders reducing rates on specific countries as agreements are announced.
- Punitive instrument: Tariff escalation as an alternative to financial sanctions. These target countries or sectors where the administration wants to signal consequences without triggering the dollar-based financial system. Rates in this category tend to be more durable and less negotiable.
- Macroeconomic tool: Tariffs intended to protect domestic industries, reduce trade deficits, and generate duty revenue. Section 232 steel and aluminum fall squarely here. These do not expire and are the least likely to be bargained away in bilateral deals.
Active Rates by Country (June 2026)
Rates below are Reciprocal Tariff Act rates only. Add Section 232, Section 301, and base HTSUS duties for your total landed cost. Rates reflect the post-IEEPA ruling environment — verify current status against CBP entry guidance before any purchasing decision.
Highest-rate import origins
- China: 145% (reciprocal) + 7.5%–25% (Section 301) + base HTSUS duty
- Cambodia: 49%
- Vietnam: 46%
- Bangladesh: 37%
- Thailand: 36%
- Indonesia: 32%
- India: 26%
- European Union: 20% (90-day pause expired; full rate reinstated)
- Rest of world: 10% universal baseline
Countries outside the Reciprocal Tariff Act
Canada and Mexico fall under USMCA and are excluded from the Reciprocal Tariff Act framework. Steel and aluminum from both countries still face Section 232 duties. The 10% baseline applies to all other trading partners not assigned a higher country-specific rate.
Exempted product categories
- Pharmaceutical products (select Chapter 30 HTS codes)
- Semiconductors and silicon wafers
- Energy: crude oil, LNG, uranium
- Steel and aluminum products already subject to Section 232 (no reciprocal rate stacking)
Duty Stacking and Total Landed Cost
Most importers underestimate real duty cost by looking at one rate at a time. Stacking across all four authorities produces the true effective rate at CBP entry. Understanding tariff mitigation strategies that address each layer is essential for protecting margins in 2026. The examples below show why single-rate lookups are insufficient for landed cost planning.
China: furniture (HTS 9403)
- Base HTSUS Column 1 duty: 0%
- Section 301 List 3: 25%
- Reciprocal Tariff Act: 145%
- Total: 170%
China: hot-rolled steel coil (HTS 7208)
- Base HTSUS Column 1 duty: ~0%
- Section 232 steel: 25%
- Section 301 List 1: 25%
- Reciprocal Tariff Act: 145%
- Total: 195%+
Vietnam: apparel (HTS 6204)
- Base HTSUS Column 1 duty: ~12%
- Reciprocal Tariff Act: 46%
- Total: ~58%

How Control Tower Tariff Tracker Works
Policy trackers like the Atlantic Council’s Trump Tariff Tracker provide authoritative legal and policy analysis — covering which statutes apply, how courts are ruling, and what the strategic intent is behind each tariff action. That context is valuable for procurement and legal teams following the policy landscape.
For logistics and supply chain operations teams, the gap is the connection between policy and execution. Knowing China faces 145% tariffs is one thing. Knowing which of your 200 open purchase orders from Guangdong factories are affected, what the duty impact is on each HTS code in your mix, and which shipments are currently in transit with incorrect duty estimates — that requires live shipment data connected to current tariff rates. That is what the Control Tower platform delivers.
Real-time rate feeds
- Syncs live from U.S. Customs, USTR, and global regulatory sources.
- Applies current rates to open POs and in-transit cargo by HTS code and origin.
- Alerts when exemptions shift or stacking rules change — including post-ruling Section 301 additions.
- Flags de minimis changes affecting e-commerce shipments (China de minimis exemption suspended May 2, 2026).
Shipment-level tariff intelligence
- Shipment-specific: see duties on a PO from Vietnam before it clears CBP.
- Custom notifications: track specific HS codes, countries, or product categories.
- Landed cost simulator: model rate changes (10% vs 46%) across suppliers before committing.
- Historical trends: review past duty impacts for supplier negotiations.
- One platform: visibility, tariffs, and exceptions without switching tools.
For small and mid-sized importers, enterprise tariff intelligence is included with CargoTrans forwarding services. Our trade advisory services team is available to review your HTS mix, check origin documentation, and calculate the real duty impact of stacked tariffs on your margins.
Effective supply chain risk management in 2026 requires connecting tariff intelligence to shipment data. Importers who watch rate tables in one tool and track shipments in another are always one executive order behind. The Control Tower platform closes that gap by applying live tariff data to your specific cargo as it moves. Pair it with our supply chain visibility software to monitor every leg — from origin factory to customs clearance — in a single dashboard.
Frequently Asked Questions
What is the current Trump tariff rate on China?
The Reciprocal Tariff Act rate on China is 145%. Add Section 301 duties (7.5%–25% depending on the product list) and the base HTSUS Column 1 rate. Steel products add Section 232 at 25%. Most Chinese manufactured goods face a total effective rate between 170% and 200%.
Did the Supreme Court strike down Trump tariffs?
In February 2026, the Supreme Court ruled 6-3 that IEEPA does not independently authorize tariff imposition, invalidating the legal basis for approximately 75% of the administration’s tariff authority. The administration responded by expanding Section 301 and Section 232 investigations to cover similar product and country scope under more established statutory authority. Tariff collection under those authorities continues. For the most current legal status, the Atlantic Council’s Trump Tariff Tracker provides ongoing legal analysis.
Do Trump tariffs apply to Canada and Mexico?
Canada and Mexico are excluded from the Reciprocal Tariff Act. USMCA governs most of their trade with the U.S. Steel and aluminum from both countries still face Section 232 duties at 25%. A Section 122 surcharge, if activated, would apply to Canada and Mexico.
What is the 90-day tariff pause?
In April 2026, the administration paused rates for more than 75 countries, reducing them to 10% for 90 days. China was excluded. The pause can end before 90 days through a new executive order. Verify the current rate before booking any shipment.
How do I calculate total landed cost under Trump tariffs?
Add four layers: (1) base HTSUS Column 1 duty, (2) Section 301 rate if the product is from China and on a USTR list, (3) Section 232 rate if the product is steel, aluminum, copper, or auto parts, (4) Reciprocal Tariff Act rate for the country of origin. Use the China to U.S. tariff calculator for HTS-level breakdowns.
Which products are exempt from Trump tariffs?
The Reciprocal Tariff Act exempts pharmaceuticals (select Chapter 30 codes), semiconductors, silicon wafers, energy products (crude oil, LNG, uranium), and steel/aluminum already covered by Section 232. CBP publishes exemption updates in the Federal Register. Exemptions change frequently.
What is tariff stacking?
Tariff stacking occurs when multiple duties apply to the same shipment simultaneously. A Chinese steel product in 2026 pays the base HTSUS duty, plus Section 301 (25%), plus Section 232 (25%), plus the Reciprocal Tariff Act (145%). All four rates are additive, not alternative.
How does Section 301 differ from IEEPA tariffs?
IEEPA tariffs can be imposed immediately by executive order once an emergency is declared. Section 301 tariffs require a formal investigation with a statutory determination period of up to 12 months, public comment periods, and USTR review. Section 301 tariffs also expire after four years unless extended. After the Supreme Court’s February 2026 IEEPA ruling, Section 301 is now the administration’s primary broad-tariff vehicle — which means future rate changes may come with more procedural lead time but also more legal durability than the IEEPA-era structure.
