Customs Bonded Warehouse: Defer Duties Up to 5 Years (19 CFR 19)

A customs bonded warehouse is a CBP-approved storage facility where imported goods can be held for up to five years without paying U.S. import duties. The legal authority is 19 USC §1555-1565. CBP regulations under 19 CFR Part 19 set the operating requirements. Duties are owed only when the importer withdraws goods for consumption into U.S. commerce. If goods are exported without entering the U.S. market, no duties are collected. In the current tariff environment, bonded warehouse status gives importers a practical tool to defer duty payments on Section 301, Section 232, and Reciprocal Tariff Act exposure while managing cash flow and monitoring rate changes.

Every bonded warehouse operates under a Continuous Customs Bond. The Importer of Record is responsible for duties from the moment goods are withdrawn for consumption. CBP supervises through periodic audits and requires the warehouse operator to maintain detailed inventory records under 19 CFR Part 144.

How Long Goods Can Stay in a Bonded Warehouse (5-Year Rule)

The five-year clock starts on the date of importation, not the date of bonded warehouse entry. If goods arrive at the port on January 1, they must be withdrawn or re-exported by December 31 five years later. Failure to withdraw or export before the deadline triggers a general order and potential abandonment or seizure by CBP. Track entry dates carefully, especially for slow-moving inventory. The warehouse and distribution team manages bonded inventory tracking as part of the compliance program.

The 11 Classes of Bonded Warehouses (19 CFR 19.1)

CBP regulations define 11 distinct bonded warehouse classes. Each class has specific permitted activities and product restrictions.

Which Class Fits Each Business Model

  • Class 1: Used for storing imports belonging to the public. General merchandise storage. Most common for third-party logistics providers.
  • Class 2: Private warehouse used exclusively by the importer who owns the goods. No public storage.
  • Class 3: Public bonded warehouse that also bottles, packs, or repacks merchandise for the importer’s account.
  • Class 4: Bonded warehouse for distilled spirits, wines, and beer. Regulated by both CBP and the Alcohol and Tobacco Tax and Trade Bureau.
  • Class 5: Manufacturing bonded warehouse. Goods can be manufactured under bond with duties deferred on inputs. Finished goods withdrawn for consumption pay duties on the finished product.
  • Class 6: Smelting and refining warehouse. For metal ores and scrap that are processed into primary metals.
  • Class 7: Duty-free stores. Located at international airports and border crossings. Goods sold to travelers departing the U.S.
  • Class 8: Bonded yards or sheds for heavy or bulky merchandise. Used for items that cannot be conveniently stored indoors.
  • Class 9: General order warehouse. Holds unclaimed, abandoned, or seized merchandise until disposition is determined by CBP.
  • Class 10: Bonded livestock facilities. For live animals in transit or pending customs clearance.
  • Class 11: Bonded carriers and freight forwarders. Covers transportation bonds for in-bond movements between ports.

For most importers using bonded warehouse status as a tariff strategy tool, Class 2 (private) or Class 1 (third-party logistics) are the relevant options. The customs brokerage services team advises on which class fits your product type and ownership structure.

Bonded Warehouse vs Foreign-Trade Zone

Both structures defer duties on imports and allow duty-free re-export. The differences determine which is right for a given operation.

Cost Comparison

A bonded warehouse requires a Continuous Customs Bond (typically 10% of estimated annual duties, minimum $50,000) and per-entry filing fees. Setup time is shorter than an FTZ. An FTZ requires an application to the FTZ Board (6-18 months), activation fees, and ongoing compliance software. For lower-volume operations, a bonded warehouse costs less to operate. For high-volume importers processing or manufacturing goods, the FTZ’s inverted tariff and weekly entry benefits often justify the higher setup cost.

Operational Complexity

Bonded warehouses have simpler recordkeeping requirements than FTZs. CBP does not require a specialized inventory control system, only accurate records of entries and withdrawals. FTZs require an FTZ Board-approved inventory control and recordkeeping system with real-time tracking. The Foreign-Trade Zones explained article covers the full FTZ operational framework.

Duty Treatment Differences

The most important operational difference: in a bonded warehouse, duties apply at the rate in effect at the time of withdrawal for consumption, not at the time of entry. If Section 301 rates drop, or if an exclusion is granted while goods sit in the warehouse, the importer pays the lower rate at withdrawal. This makes a bonded warehouse a useful tool for importers waiting on pending exclusion decisions or expecting rate reductions.

EXPLORE CAPTAIN

Withdrawing goods from a bonded warehouse follows distinct procedures depending on whether goods enter U.S. commerce or are exported. The forms and duty implications differ for each path.

Forms 7501 and 7512

Withdrawal for consumption uses CBP Form 7501 (Entry Summary). This is the standard import entry form. Duties, fees, and taxes are paid at this point. Withdrawal for exportation uses CBP Form 7512 (Transportation Entry and Manifest). No duties are collected on goods exported directly from a bonded warehouse.

Duty Calculation at Withdrawal Date vs Entry Date

The duty rate applied is the rate in effect on the withdrawal date, not the date goods originally entered the bonded warehouse. This creates both opportunity and risk. If rates increase after entry, the importer pays the higher withdrawal-date rate. If rates decrease (or exclusions are granted), the importer benefits from the lower rate. Monitoring rate changes with the tariff consulting firm team helps time withdrawals to minimize duty exposure.

Book advisory call

A bonded warehouse functions as a timing tool. The scenarios below show where it delivers the most value in the current tariff environment.

Section 301 Exposure Timing

An importer expecting a USTR exclusion decision on a specific HTS code can admit goods to a bonded warehouse and wait. If the exclusion is granted, the importer withdraws at zero Section 301 rate. If denied, the importer withdraws at the standard rate and pays duties. The five-year window gives significant flexibility for long-running exclusion review processes.

Slow-Moving Inventory Cash Flow

For products with long sales cycles (capital equipment, specialty chemicals, high-value components), bonded warehouse status defers a large duty payment until the sale is made. The importer does not pay duties on inventory that has not yet generated revenue. This aligns duty payment with cash receipts from customers. The trade advisory services team models the working capital impact versus the Continuous Bond cost before recommending bonded entry.

Compliance, Bond Requirements and CBP Audits

The Continuous Customs Bond must cover estimated duties, taxes, and fees for all goods in the warehouse at any given time. CBP can require an increase in bond coverage if inventory levels or duty rates increase significantly. CBP conducts periodic audits of bonded warehouse operations. Deficiencies in recordkeeping, unauthorized removals, or failure to pay duties on withdrawal can result in bond forfeiture and warehouse decertification. Maintain accurate entry-level records using warehouse management software for every lot admitted and every withdrawal made. Use the duty drawback services workflow to recover duties on bonded goods that are subsequently exported as part of manufactured finished goods.

Frequently Asked Questions

How long can goods stay in a bonded warehouse?

Five years from the date of importation. The five-year clock runs from the original import date, not the date goods entered the bonded warehouse. Goods not withdrawn or exported within five years are subject to general order and potential abandonment.

What is the difference between a bonded warehouse and an FTZ?

A bonded warehouse is storage-only and does not allow manufacturing or processing. An FTZ allows manufacturing, offers inverted tariff relief and weekly entry filing, and requires FTZ Board activation. Both defer duties and allow duty-free re-export. Bonded warehouses are faster and cheaper to set up; FTZs provide more operational benefits for manufacturers.

Do I pay tariffs on goods stored in a bonded warehouse?

No, not while goods remain in the warehouse. Duties are owed only when goods are withdrawn for consumption into U.S. commerce. The rate that applies is the rate in effect on the withdrawal date.

How much does a bonded warehouse cost?

Costs include the Continuous Customs Bond premium (typically 1-3% of the bond amount annually), warehouse storage fees, and customs broker fees for entry filing. The bond amount is typically 10% of estimated annual duties, with a minimum of $50,000. Third-party bonded warehouses charge storage fees similar to general warehousing rates.

What are the 11 classes of bonded warehouses?

The 11 classes under 19 CFR 19.1 cover: public storage (Class 1), private storage (Class 2), bottling/packing (Class 3), distilled spirits (Class 4), manufacturing (Class 5), smelting and refining (Class 6), duty-free stores (Class 7), bulk yards (Class 8), general order (Class 9), livestock (Class 10), and bonded carriers (Class 11).

Can I re-export from a bonded warehouse duty free?

Yes. Goods withdrawn from a bonded warehouse for exportation using CBP Form 7512 owe no U.S. import duties. This applies regardless of the Section 301, Section 232, or Reciprocal Tariff Act rates in effect at the time of export.

What happens if duties change while goods are in the bonded warehouse?

The rate in effect on the withdrawal date applies. If rates increase, you pay more when you withdraw. If rates decrease or an exclusion is granted, you pay less. This makes a bonded warehouse valuable when exclusion decisions or rate negotiations are pending.

A bonded warehouse buys up to five years of tariff timing flexibility on any shipment. The customs brokerage services team handles bonded entry filing and withdrawal management. The trade advisory services team models duty deferral savings against Continuous Bond costs and timing scenarios to determine whether bonded entry makes sense for your inventory profile.

Foreign-Trade Zones (FTZ): Defer and Eliminate Import Duties

A Foreign-Trade Zone (FTZ) is a CBP-supervised area within the U.S. where imported goods can be stored, processed, or manufactured without entering U.S. customs territory. Duties are deferred until goods leave the zone and enter U.S. commerce. If goods are re-exported, no U.S. duties apply at all. The program was created by the Foreign-Trade Zones Act of 1934 (19 USC §81a-81u) and is one of the most powerful tariff strategy tools available to mid-market and large importers operating in the current high-tariff environment.

FTZ operations are governed by two regulatory frameworks: the Foreign-Trade Zones Board (Commerce Department) under 15 CFR Part 400 handles zone designation and oversight, while U.S. Customs and Border Protection (CBP) governs day-to-day zone operations under 19 CFR Part 146. Every admission of merchandise into an FTZ requires CBP Form 214 (Admission Application).

How an FTZ Works

Goods entering an FTZ are not subject to U.S. import duties at the time of admission. CBP monitors the zone through activation agreements and periodic audits. The importer or zone operator tracks merchandise inside the zone and files a CBP entry only when goods are withdrawn for consumption into the U.S. market. If goods are re-exported, the entry is never filed and no U.S. duty is ever owed.

General-Purpose Zones vs Subzones

General-purpose zones are public FTZ facilities, typically operated by port authorities or industrial park operators. Any company can apply to use space in a general-purpose zone without holding its own zone grant. Subzones are company-specific zones authorized for a single manufacturer or operator. A subzone allows a factory floor or warehouse to operate under FTZ status without being physically located in a general-purpose zone. Subzones require a separate application to the FTZ Board.

FTZ Board and Grantee Structure

The FTZ Board (chaired by the Secretary of Commerce) grants zone status to a grantee, which is typically a state or local government entity or a port authority. The grantee then sponsors operators who use the zone for their import and manufacturing operations. The grantee is responsible for overall zone compliance. The operator is responsible for day-to-day recordkeeping and CBP reporting. An importer can be both grantee and operator in a subzone structure.

FTZ Benefits for U.S. Importers

Duty Deferral (Cash Flow Impact)

Without an FTZ, duties are owed at the time of CBP entry filing, which happens when goods arrive at the port. With an FTZ, duties are owed only when goods are withdrawn for consumption. A company that turns inventory every 60 days defers duties by 60 days per cycle. On $10 million in annual tariff exposure at a 25% combined rate, deferring $2.5 million in duty payments by 60 days generates meaningful working capital savings. The tariff consulting firm team models the cash flow impact against FTZ setup and operating costs before recommending activation.

Duty Elimination on Re-Exports

Goods admitted to an FTZ and subsequently exported without entering U.S. commerce owe zero U.S. duties. This is absolute elimination, not deferral. For importers who also export (manufacturers, distributors supplying foreign customers), FTZ status converts duty-paid imports into duty-free inputs for re-export. Combine this with duty drawback services modeling to identify which path produces the higher recovery on re-exported goods.

Weekly Entry (Filing and MPF Savings)

Standard import practice requires a CBP entry filing per shipment. The Merchandise Processing Fee (MPF) is 0.3464% of the dutiable value, with a minimum of $32.71 and a maximum of $608.37 per entry. FTZ operators can consolidate all withdrawals for a seven-day period into one weekly entry. An importer receiving 20 shipments per week files 1 entry instead of 20, reducing MPF exposure by up to 95% on the fixed-cost portion. The customs brokerage services team handles weekly entry filing as part of the FTZ activation package.

Inverted Tariff Relief

An inverted tariff situation exists when the duty rate on a finished manufactured product is lower than the duty rate on one or more of its components. In an FTZ, a manufacturer can elect to pay duty on the finished product HTS rate rather than on the imported component rates. If steel components (Chapter 73, 25% Section 232) are used to manufacture a finished industrial product (Chapter 84, 0-2% Column 1 duty), the manufacturer pays duty at the finished product rate. The savings per unit can be substantial at current tariff levels.

FTZ vs Customs Bonded Warehouse

Both structures defer duties, but they serve different operational profiles:

  • FTZ: Allows manufacturing, processing, and assembly. Re-exports are duty-free. Weekly entry reduces MPF. Inverted tariff election available. Requires FTZ Board activation (6-18 months). Higher ongoing compliance cost.
  • Customs bonded warehouse: Storage only. No manufacturing. Re-exports are duty-free. Duties paid at withdrawal rate (rate in effect at withdrawal, not entry). Faster to set up. Lower ongoing cost. 5-year storage limit.

For importers that process or manufacture goods, FTZ status provides more levers. For importers that only store and resell, the customs bonded warehouse strategy or tariff engineering is simpler and faster to activate. The trade advisory services team runs a decision matrix based on your product mix, re-export volume, and manufacturing operations before recommending either structure.

EXPLORE CAPTAIN

Activating FTZ status requires a two-step approval process through the FTZ Board and CBP. Timeline and cost vary by zone type and structure.

Cost and Timeline

Activation requires an application to the FTZ Board, a CBP activation agreement, and appointment of a zone operator. The FTZ Board reviews applications and issues a grant of authority, which typically takes 6-18 months. Ongoing costs include CBP activation fees, operator compliance software, and customs broker support for weekly entry filing. Setup costs typically range from $50,000 to $150,000 for a subzone depending on complexity.

Compliance and Recordkeeping Requirements

FTZ operators must maintain an inventory control and recordkeeping system (ICRS) approved by CBP. All admissions, manipulations, and withdrawals must be documented. CBP conducts periodic audits. The Foreign-Trade Zones Act of 1934 (19 USC §81a-81u) sets the legal framework; 15 CFR Part 400 sets the Board’s procedural rules; 19 CFR Part 146 sets CBP’s operational requirements. Non-compliance can result in suspension of FTZ status.

Common Mistakes That Void FTZ Benefits

  • Admitting goods after the proclamation effective date: Duties for Section 301 or Reciprocal Tariff Act purposes are assessed at the rate in effect at the time of withdrawal, not admission. FTZ does not freeze the rate at admission. Only certain zone-specific elections can lock in pre-proclamation rates for specific circumstances.
  • Manufacturing without CBP approval: Manufacturing in an FTZ requires a manufacturing authority from the FTZ Board. Storage-only zones cannot perform manufacturing without separate approval.
  • Inadequate recordkeeping: CBP can decertify FTZ status for systemic recordkeeping failures. Every admission and withdrawal must be documented in the ICRS.
  • Misapplying the inverted tariff election: The election requires the finished product HTS code to have a lower rate than the component. Confirm the HTS classification of both before filing the election.

Frequently Asked Questions

What is a Foreign-Trade Zone?

A Foreign-Trade Zone is a CBP-supervised area within U.S. borders where imported goods can be stored, processed, or manufactured without triggering U.S. import duties. Duties are owed only when goods leave the zone and enter U.S. commerce. Re-exported goods owe no U.S. duties.

How much can importers save with an FTZ?

Savings vary by product and volume. Duty deferral improves working capital. MPF savings from weekly entry can exceed $300,000 annually for high-volume importers. First Sale for Export reduces the dutiable value before FTZ admission, compounding savings. Inverted tariff relief can reduce the effective duty rate by 15-25 percentage points on manufactured goods. Model the savings against setup costs before committing.

What is the difference between an FTZ and a bonded warehouse?

An FTZ allows manufacturing and processing; a bonded warehouse is storage-only. An FTZ offers inverted tariff election and weekly entry benefits; a bonded warehouse does not. FTZ setup takes 6-18 months; a bonded warehouse can be operational faster. Both defer duties and allow duty-free re-export.

How long does FTZ activation take?

6-18 months from application submission to FTZ Board grant and CBP activation. Subzone applications for a single manufacturer can sometimes be processed faster if the Board has expedited review procedures available.

Can FTZ goods be re-exported duty free?

Yes. Goods admitted to an FTZ and subsequently exported without entering U.S. commerce owe zero U.S. import duties. This applies regardless of Section 301, Section 232, or Reciprocal Tariff Act rates in effect at the time.

Does an FTZ help against Section 301 tariffs?

For re-exports, yes. Section 301 duties are eliminated on goods that leave the FTZ as exports. For domestic consumption, Section 301 duties still apply at withdrawal. The FTZ defers payment but does not eliminate duties on goods entering U.S. commerce.

What is inverted tariff relief in an FTZ?

Inverted tariff relief allows a manufacturer in an FTZ to pay duty on the finished product HTS rate rather than on the component rates when the finished product rate is lower. This applies when assembling finished goods from high-duty components into a lower-tariff final product category.

An FTZ is one of the highest-leverage tariff tools available to mid-market importers operating in the current environment. The tariff consulting firm team assesses whether your import profile justifies FTZ activation. The trade advisory services team models deferral savings, MPF reduction, and inverted tariff opportunities against your current duty exposure before the first application is filed.

FTZ vs Bonded Warehouse: Which Strategy Saves More on Duties?

Foreign trade zones (FTZs) and bonded warehouses are two of the most powerful duty deferral tools available to U.S. importers. Both allow goods to enter U.S. territory without triggering customs entry — and the associated duty payment — until the goods are formally entered for consumption. In a high-tariff environment, the difference between the two structures can represent millions of dollars in annual cash flow and, in some cases, a permanent duty reduction. Choosing between them requires understanding their distinct operational rules, merchandise processing permissions, and cost structures.

What Is a Foreign Trade Zone?

A foreign trade zone is a federally designated area within the United States that is legally considered outside U.S. Customs territory for tariff purposes. FTZs are established under the Foreign Trade Zones Act of 1934 and administered by the Foreign Trade Zones Board (a joint Commerce/Treasury body) and U.S. Customs and Border Protection (CBP). Goods admitted to an FTZ can be stored, exhibited, assembled, manufactured, or processed without paying duties or merchandise processing fees (MPF) until the goods are entered for consumption into the U.S. market.

Types of FTZ Status

  • General-purpose zone: a designated area (often a port or industrial park) available to multiple users. Any company can apply for activated status within the zone.
  • Subzone / alternative site: a company-specific FTZ designation at the importer’s own facility. Requires FTZ Board approval and is typically justified by high import volume or significant manufacturing activity.

What Is a Bonded Warehouse?

Trade Advisory

Talk to a senior trade strategist this week

A 30-minute working session to map your bridge-tariff exposure, AIPA refund posture and DDP risk — then a clear action plan, not a sales deck.

Book advisory call

A bonded warehouse is a CBP-approved facility where imported goods can be stored for up to five years without payment of duties. The warehouse operator posts a bond with CBP guaranteeing duty payment when goods are eventually withdrawn for consumption. Unlike FTZs, bonded warehouses do not allow manufacturing or substantial transformation of the stored goods. Manipulation (sorting, repacking, cleaning, labeling) is permitted to the extent it does not change the character of the goods.

Key Operational Differences

Feature FTZ Bonded Warehouse
Merchandise processing fee Deferred (paid on formal entry) Deferred (paid on withdrawal)
Harbor maintenance fee FTZs may be exempt under certain conditions Not exempt
Manufacturing allowed? Yes (with FTZ Board approval for production authority) No — manipulation only
Country of origin change Possible if substantial transformation occurs Not possible
Duty rate applied Choice of rate on admission or at time of entry Rate at time of entry (withdrawal)
Storage period Unlimited Maximum 5 years
Destruction without duty Yes Yes
Re-export without duty Yes Yes
Weekly entry consolidation Yes (direct delivery/weekly entry) No (entry per withdrawal)

The Inverted Tariff Benefit: FTZ’s Unique Advantage

The most powerful FTZ benefit that bonded warehouses cannot replicate is the inverted tariff election. In an FTZ with manufacturing production authority, the importer can elect at the time of formal entry whether to pay the tariff rate applicable to the foreign components admitted to the zone OR the rate applicable to the finished product manufactured in the zone. If the finished product carries a lower tariff rate than the components, the importer pays the lower rate on the final goods — even though the foreign components were used in their production.

Example: A U.S. manufacturer imports foreign steel components dutiable at 25% (Section 232) and uses them to produce industrial machinery in an FTZ. The machinery HTS code carries a 2.5% MFN rate. Under FTZ inverted tariff rules, the manufacturer may elect to pay 2.5% on the finished machinery rather than 25% on the imported steel components — a significant tariff reduction, not merely a deferral.

This benefit is particularly significant in the current Section 232 and Liberation Day environment, where input tariffs can dramatically exceed finished goods tariff rates. Our tariff consulting firm regularly models FTZ inverted tariff savings versus bonded warehouse deferral to identify which structure delivers greater long-term benefit.

Weekly Entry Consolidation: The MPF Benefit

FTZs permit weekly consolidated entry under CBP’s direct delivery and weekly entry procedures. Rather than filing a separate customs entry for each shipment (incurring the per-entry MPF charge, currently $32.71 per entry), an FTZ operator files one weekly entry for all goods withdrawn for consumption during that week. At high import volumes, this MPF consolidation alone can save tens of thousands of dollars annually.

Bonded warehouses require a separate CBP entry for each withdrawal, and the MPF is assessed at that time. High-volume operations may partially offset this by managing withdrawal timing, but the per-entry fee accumulates.

Duty Rate Timing Risk: When Bonded Warehouse May Be Preferred

In a falling-tariff environment (for example, if a bilateral deal reduces the applicable rate on a product), a bonded warehouse can be strategically advantageous: store the goods until the lower rate takes effect, then withdraw for consumption at the reduced rate. FTZ admission typically locks in the rate election methodology at the time of admission, though the actual rate is determined at entry time.

Conversely, in a rising-tariff environment, withdrawing goods from a bonded warehouse before a rate increase can capture the lower rate. Importers monitoring Liberation Day negotiations and bilateral deal timelines actively manage their bonded warehouse withdrawal schedules to optimize tariff exposure. Our trade advisory services team tracks rate trajectory signals to inform withdrawal timing decisions.

EXPLORE CAPTAIN

FTZs have higher setup costs and more regulatory complexity than bonded warehouses:

  • FTZ: requires FTZ Board activation (a multi-month process for new subzones), CBP operating procedures approval, zone inventory control system implementation, and annual reporting to the FTZ Board. Production authority for manufacturing requires a separate application. Total setup typically takes six to eighteen months.
  • Bonded Warehouse: CBP approval required (Class 2-7 depending on use type), bond posted by the operator, CBP procedures approved. Timeline typically two to six months. Lower ongoing compliance burden.

For importers with straightforward storage and re-export needs and moderate import volume, a bonded warehouse is often the right choice. For high-volume importers with manufacturing operations or significant inverted tariff potential, FTZ subzone status frequently delivers superior economics despite the higher setup investment.

FTZ and Bonded Warehouse Under Liberation Day Conditions

The Liberation Day 10% IEEPA baseline and country-specific Annex II rates can be deferred through both structures. FTZ and bonded warehouse deferral is particularly valuable for importers who believe ongoing court litigation may result in refunds or rate reductions: goods held in an FTZ or bonded warehouse at the time a court ruling changes the applicable rate benefit from the revised rate on formal entry. For IEEPA tariff recovery mechanisms beyond deferral, see our guide on IEEPA tariff refunds.

The Tariff Response Unit at CargoTrans provides FTZ feasibility assessments tailored to the current tariff environment, evaluating inverted tariff potential, MPF savings, and deferral benefit across a client’s full import program. The assessment typically identifies whether the capital investment in FTZ activation is justified given current tariff rates and product mix.

Frequently Asked Questions

What is a foreign trade zone?

A foreign trade zone is a federally designated area within the United States that is legally outside U.S. Customs territory for tariff purposes. Goods in an FTZ can be stored, manufactured, or processed without paying duties until formally entered for consumption. FTZs are established under the Foreign Trade Zones Act of 1934 and administered by the FTZ Board and CBP.

What is a bonded warehouse?

A bonded warehouse is a CBP-approved storage facility where imported goods can be stored for up to five years without payment of duties. The operator posts a bond guaranteeing duty payment on withdrawal for consumption. Manufacturing is not permitted; limited manipulation (sorting, repacking, labeling) is allowed.

Can I manufacture goods in a bonded warehouse?

No. Bonded warehouses allow storage and limited manipulation that does not change the character of the goods. Manufacturing, substantial transformation, or assembly operations require FTZ production authority. Any goods that undergo manufacturing in a bonded warehouse lose their bonded status.

What is the inverted tariff benefit in an FTZ?

The inverted tariff benefit allows a manufacturer in an FTZ with production authority to elect, at the time of formal entry, to pay the duty rate on the finished manufactured product rather than on the foreign components used in production. If the finished product carries a lower rate than the components (an “inverted tariff” situation), the manufacturer pays the lower rate — a permanent duty reduction, not just deferral.

How long can goods stay in a bonded warehouse?

Goods may remain in a bonded warehouse for up to five years from the date of importation. After five years, the goods must be entered for consumption (paying duties), exported, or destroyed. An FTZ has no statutory time limit on storage.

Which is better for my import program, FTZ or bonded warehouse?

The answer depends on your product mix, import volume, and operational model. Bonded warehouses are simpler and faster to set up and work well for storage and re-export operations. FTZs deliver greater benefit for high-volume importers, particularly those with manufacturing operations that can benefit from the inverted tariff election and MPF weekly entry consolidation. A tariff consulting analysis of your specific product portfolio and import flows is the most reliable way to compare the economics.

Can an FTZ eliminate Section 232 tariffs on steel?

Not eliminate, but potentially reduce. If a manufacturer uses imported steel in an FTZ to produce a finished product that carries a lower duty rate than the steel components, the inverted tariff election allows the manufacturer to pay the finished product rate rather than the 25% Section 232 steel rate. The total tariff paid is lower, though not zero unless the finished product rate is zero.

Evaluate Your Duty Deferral Options

FTZ and bonded warehouse structures are among the highest-leverage tariff optimization tools available under the current tariff environment. Our trade advisory services team and tariff consulting practice evaluate both options against your actual import data to identify which structure — or combination — maximizes duty savings and cash flow benefit for your specific operation.
