A Foreign Trade Zone (FTZ) and a bonded warehouse both allow U.S. importers to defer customs duties. But they work differently, cost differently, and suit different operations. In the current tariff environment, where effective duty rates have quadrupled since 2024, choosing the right deferral strategy can save hundreds of thousands of dollars. Here is how each option works, when to use which, and how to leverage both during the Section 122 surcharge window.
Key Takeaways
Both FTZs and bonded warehouses defer duty payment until goods enter U.S. commerce. If goods are re-exported, no duty is paid.
Bonded warehouses assess duty at the rate in effect at the time of withdrawal, not at the time of importation. This means goods imported during the Section 122 surcharge period and withdrawn after July 24, 2026, may avoid the 10% surcharge entirely.
FTZs allow full manufacturing and assembly. Bonded warehouses allow only sorting, repacking, and other manipulation, not manufacturing.
FTZ goods admitted after February 24, 2026, must be entered in privileged foreign status, which locks in the duty rate at admission, including the Section 122 surcharge. This reduces the FTZ timing advantage during the surcharge period.
Bonded warehouses have a five-year storage limit. FTZs have no time limit on storage.
There are approximately 200 FTZ warehouses in the U.S. compared to more than 1,700 bonded warehouses, making bonded storage far more accessible for most importers.
What Is a Foreign Trade Zone?
A Foreign Trade Zone is a designated area within the United States that is legally considered outside U.S. customs territory for duty purposes. FTZs are authorized under the Foreign Trade Zones Act of 1934 and administered by the Foreign-Trade Zones Board, which is part of the U.S. Department of Commerce.
The short answer is: goods inside an FTZ have not officially entered the United States for customs purposes. Duty is not owed until and unless those goods are withdrawn from the zone and entered into U.S. commerce. If goods are exported from the FTZ, no duty is ever paid.
FTZs exist in every U.S. state. Your own manufacturing facility can become a sub-zone. FTZs allow receiving, storing, assembling, manufacturing, and re-exporting goods without triggering duty payment.
What Is a Bonded Warehouse?
A bonded warehouse is a CBP-authorized secure facility where imported goods can be stored for up to five years without payment of duties. Bonded warehouses are authorized under 19 U.S.C. § 1555 and regulated under 19 CFR Part 19.
The short answer is: goods in a bonded warehouse have entered the United States but have not been released into domestic commerce. Duty is deferred until the goods are withdrawn for consumption. If goods are re-exported from the bonded warehouse, no duty is paid.
Key definition: Privileged foreign status is an FTZ classification that locks in the applicable duty rate based on the date the goods are admitted to the zone. Under the Section 122 proclamation, goods admitted to an FTZ after February 24, 2026, must generally be entered in privileged foreign status, meaning the Section 122 surcharge rate is locked in at admission.
Key definition: Withdrawal for consumption is the act of removing goods from a bonded warehouse and formally entering them into U.S. commerce. The duty rate applied is the rate in effect on the date of withdrawal, not the date of original importation or warehouse admission.
How Do FTZs and Bonded Warehouses Compare?
| Feature | Foreign Trade Zone (FTZ) | Bonded Warehouse |
|---|---|---|
| Duty trigger | Withdrawal into U.S. commerce | Withdrawal for consumption |
| Duty rate timing | Locked at admission (privileged foreign status) or at withdrawal (non-privileged) | Rate in effect at time of withdrawal |
| Manufacturing allowed | Yes, full manufacturing and assembly | No, only sorting, repacking, relabeling, cleaning |
| Storage time limit | No limit | Five years from date of importation |
| Re-export without duty | Yes | Yes |
| Merchandise Processing Fee | Weekly consolidated entry reduces MPF | Standard MPF per entry |
| Setup complexity | High (FTZ Board approval, extensive security and compliance requirements) | Moderate (CBP application and bond required) |
| Number of U.S. locations | Approximately 200 | More than 1,700 |
| Property tax exemption | Yes, in most jurisdictions | No |
| Section 122 surcharge treatment | Locked in at admission (privileged foreign status required) | Assessed at withdrawal rate; can avoid surcharge if withdrawn after expiration |
| Inverted tariff benefit | Yes, can pay duty on finished product instead of components | No |
Can a Bonded Warehouse Help You Avoid the Section 122 Surcharge?
Yes. This is the single most actionable strategy available to importers during the current surcharge period.
Duty in a bonded warehouse is assessed at the rate in effect at the time of withdrawal for consumption, not at the time of importation. The Section 122 surcharge is a temporary 10% ad valorem duty that expires on July 24, 2026, unless Congress votes to extend it (which requires affirmative legislative action). If you import goods during the surcharge period, admit them to a bonded warehouse, and withdraw them after July 24, the Section 122 surcharge does not apply.
Here is the math on a concrete example. An importer brings in $45 million worth of consumer electronics during the surcharge period. The Section 122 surcharge adds $4.5 million in duty. If the importer instead admits the goods to a bonded warehouse and defers withdrawal until after July 24, the entire $4.5 million surcharge is avoided. The cost of the strategy is bonded warehouse storage fees (typically $0.50 to $2.00 per square foot per month in major logistics corridors) plus the carrying cost of capital tied up in inventory that cannot be sold until withdrawn. For high-value, compact merchandise like electronics, automotive components, and industrial equipment, the storage cost is often a small fraction of the duty savings.
Goods can remain in a bonded warehouse for up to five years, providing an extraordinarily long deferral window that far exceeds the 150-day surcharge period. Most importers pursuing this strategy will plan to withdraw goods shortly after July 24, minimizing storage costs while capturing the full duty savings.
Important caveat: The duty rate at withdrawal applies to all applicable tariffs, not just Section 122. If Section 301 rates on Chinese goods increase during the warehousing period, or if new Section 232 categories are added, those changes would also affect the total duty assessed at withdrawal. You must evaluate the full tariff landscape, not just the Section 122 surcharge, when deciding when to withdraw.
Can an FTZ Help You Avoid the Section 122 Surcharge?
The short answer is: less effectively than a bonded warehouse, due to the privileged foreign status requirement.
The Section 122 proclamation requires that goods admitted to an FTZ on or after February 24, 2026, must generally be entered in privileged foreign status. This means the applicable duty rate, including the Section 122 surcharge, is locked in at the time of admission to the zone. Unlike a bonded warehouse, where the duty rate is determined at withdrawal, the FTZ locks in the surcharge at the moment goods enter the zone.
This significantly reduces the FTZ's timing advantage during the surcharge period. However, FTZs retain other benefits that may still justify their use.
When Should You Use an FTZ Instead of a Bonded Warehouse?
FTZs are the better choice when your operation involves manufacturing, assembly, or significant processing of imported goods before they enter U.S. commerce. Specific scenarios where FTZs win include:
You manufacture products from imported components. FTZs allow full manufacturing. If you import components at high duty rates and assemble them into finished products that carry lower duty rates, you can pay duty on the finished product instead of the components. This is called an inverted tariff benefit and can produce substantial savings.
You import high volumes of shipments and want to reduce MPF costs. FTZs allow weekly consolidated entries instead of individual entries per shipment. This can reduce Merchandise Processing Fees significantly for high-volume importers.
You need indefinite storage. FTZs have no time limit on storage. Bonded warehouses cap storage at five years, after which CBP may sell the goods at auction.
You want property tax exemption on inventory. Goods stored in an FTZ are exempt from state and local property taxes in most jurisdictions. This benefit does not apply to bonded warehouses.
When Should You Use a Bonded Warehouse Instead of an FTZ?
Bonded warehouses are the better choice when you need simple, accessible duty deferral without the complexity of FTZ compliance. Specific scenarios where bonded warehouses win include:
You want to time your withdrawal to take advantage of tariff changes. This is the killer advantage in 2026. Bonded warehouse withdrawal-rate timing lets you avoid the Section 122 surcharge entirely by deferring entry until after July 24. FTZ privileged foreign status locks in the surcharge at admission.
You store finished goods for eventual distribution or re-export. If your goods do not require manufacturing or assembly, the bonded warehouse provides the duty deferral benefit without the compliance overhead of an FTZ.
You need a location quickly. With more than 1,700 bonded warehouses nationwide compared to approximately 200 FTZs, finding available bonded warehouse space is significantly easier. FTZ activation requires FTZ Board approval, which can take months.
You manage fluctuating demand. Bonded warehouses let you hold inventory without committing to U.S. entry until a buyer is confirmed. If demand drops, you can re-export without ever paying duty.
Can You Use Both at the Same Time?
Yes. Many importers use FTZs for manufacturing and value-added processing while using bonded warehouses for finished goods storage and distribution flexibility. Goods can be transferred from a bonded warehouse to an FTZ without triggering duty, as long as they remain under customs control.
This hybrid strategy is increasingly popular among importers managing complex, multi-tier supply chains where some goods need processing and others need simple deferral. For a detailed look at how duty drawback interacts with both FTZ and bonded warehouse strategies, see our duty drawback guide.
How Much Does Each Option Cost to Set Up?
| Cost Factor | FTZ | Bonded Warehouse |
|---|---|---|
| Application and approval | FTZ Board application (months-long process), legal and consulting fees of $10,000 to $50,000+ | CBP application plus surety bond, typically $2,000 to $10,000 |
| Facility requirements | 24/7 security, surveillance, fencing, full documentation compliance | Secure facility meeting CBP standards |
| Ongoing compliance | Weekly entry filing, inventory tracking, FTZ Board reporting | Standard bonded warehouse recordkeeping |
| Storage fees | Varies by location, typically comparable to bonded warehouse rates | $0.50 to $2.00 per square foot per month in major markets |
| Operational overhead | High (requires dedicated compliance staff or experienced broker) | Moderate (standard customs procedures) |
For most small and midsize importers, a bonded warehouse is the faster, cheaper, and simpler path to duty deferral. FTZs make sense when the manufacturing, inverted tariff, or MPF consolidation benefits justify the higher setup and compliance costs.
Frequently Asked Questions
What is the difference between an FTZ and a bonded warehouse?
An FTZ is a designated area legally considered outside U.S. customs territory where goods can be stored, manufactured, and re-exported without paying duty. A bonded warehouse is a CBP-authorized facility where imported goods can be stored for up to five years with duty deferred until withdrawal for consumption. The main differences are that FTZs allow manufacturing, have no storage time limit, and offer inverted tariff benefits, while bonded warehouses are simpler to set up and allow withdrawal-rate timing.
Can I avoid the Section 122 surcharge using a bonded warehouse?
Yes. Duty in a bonded warehouse is assessed at the rate in effect at the time of withdrawal, not importation. If you import goods during the surcharge period and withdraw them after the Section 122 surcharge expires on July 24, 2026, the surcharge does not apply.
Can I avoid the Section 122 surcharge using an FTZ?
Not as effectively. The Section 122 proclamation requires goods admitted to an FTZ after February 24, 2026, to be entered in privileged foreign status, which locks in the duty rate (including the surcharge) at the time of admission.
How long can goods stay in a bonded warehouse?
Up to five years from the date of importation. After five years, CBP may sell the goods at auction to recover duties owed.
How long can goods stay in an FTZ?
Indefinitely. FTZs have no statutory time limit on storage.
Can I manufacture goods in a bonded warehouse?
No. Bonded warehouses permit only manipulation activities such as sorting, repacking, relabeling, and cleaning. Full manufacturing and assembly are only permitted in FTZs (or in Class 6 bonded manufacturing warehouses, which are limited to production for export).
What is an inverted tariff, and how does an FTZ help?
An inverted tariff occurs when the duty rate on imported components is higher than the duty rate on the finished product. In an FTZ, you can elect to pay duty on the finished product rather than the components, resulting in a lower total duty. Bonded warehouses do not offer this benefit.
Do I need a customs broker to use an FTZ or bonded warehouse?
You are not legally required to use a broker, but the compliance complexity of FTZ operations and the entry procedures for bonded warehouse withdrawals make professional guidance strongly advisable. An experienced broker can also help you evaluate which strategy produces the best financial outcome for your specific product mix and import volumes.
Can goods be transferred between a bonded warehouse and an FTZ?
Yes. Goods can move between bonded warehouses and FTZs without triggering duty, as long as they remain under CBP customs control throughout the transfer.
What happens to my goods if the Section 122 surcharge is extended by Congress?
Goods in a bonded warehouse can remain there for up to five years. Even if Congress extends the surcharge, you have years of additional storage time available to wait for the rate to change. However, you should model the carrying cost of extended storage against the duty savings to determine whether continued deferral makes financial sense.
How many FTZs and bonded warehouses are there in the United States?
There are approximately 200 FTZ warehouse locations and more than 1,700 bonded warehouses nationwide. Bonded warehouse capacity is far more accessible for most importers.
Which option is better for my business?
If you manufacture or assemble imported goods, import high volumes of components with varying duty rates, or need indefinite storage flexibility, an FTZ is likely the better fit. If you need simple duty deferral, want to time withdrawals around tariff changes, or need a solution you can activate quickly, a bonded warehouse is the stronger choice. Many importers use both for different parts of their supply chain. For help determining which approach fits your import profile, consult with a licensed customs broker experienced in both programs.
This guide reflects U.S. customs regulations, FTZ rules, and bonded warehouse procedures as of April 3, 2026. The Section 122 surcharge is scheduled to expire on July 24, 2026. FTZ privileged foreign status requirements and bonded warehouse withdrawal rules are subject to change through CBP guidance and regulatory updates. Importers should consult with a licensed customs broker for guidance specific to their operations. For related strategies, see our guides on duty drawback and tariff stacking.
