Foreign Trade Zones: How to Reduce Tariff Exposure in a High-Duty Environment

What is a Foreign Trade Zone?

A Foreign Trade Zone (FTZ) is a designated location within the United States, typically near a port of entry, where foreign and domestic merchandise is considered to be in international commerce and outside U.S. Customs territory for duty purposes. Companies operating within an FTZ can defer, reduce, or eliminate customs duties on imported goods. The program was created by Congress in the Foreign-Trade Zones Act of 1934 and is administered by the Foreign-Trade Zones Board, chaired by the Secretary of Commerce.

How can an FTZ reduce import duties?

FTZs offer multiple duty-saving mechanisms: duty deferral (pay duties only when goods leave the zone for U.S. consumption), duty elimination on re-exports and scrapped goods, inverted tariff benefits (pay the lower finished-product rate instead of higher component rates), and reduced Merchandise Processing Fees through weekly entry consolidation. With U.S. tariffs at their highest since 1943, these savings can be substantial.

Foreign Trade Zones are one of the most underutilized tariff mitigation strategies available to U.S. importers. According to the FTZ Board's Annual Report to Congress, there are approximately 197 active FTZ programs across the United States, employing roughly 550,000 people at about 1,300 active operations and exporting $149 billion in merchandise. Yet many importers, particularly mid-market companies, are unaware that FTZ benefits exist or assume they are only for large manufacturers. In a tariff environment where Section 232, Section 301, and Section 122 duties can stack to rates exceeding 50%, FTZs deserve serious evaluation.

What Are the Core Benefits of Operating in an FTZ?

Duty deferral. Customs duties and federal excise taxes are deferred until goods leave the FTZ and enter U.S. commerce. This can meaningfully improve cash flow, especially for companies holding significant imported inventory. There is no time limit on storage in an FTZ, unlike bonded warehouses which impose a five-year limit. For companies importing capital equipment to build or expand U.S. manufacturing facilities, duty deferral allows them to allocate resources toward hiring, training, and facility development.

Duty elimination on re-exports. Goods that are imported into an FTZ and later exported without entering U.S. commerce are exempt from customs duties entirely. This eliminates the need for the complex and time-consuming duty drawback process, where importers first pay duties and then apply for refunds.

Duty elimination on waste and scrap. No duties are paid on goods destroyed under CBP supervision within the zone. Companies with manufacturing processes that generate significant scrap, or importers dealing with product damage, spoilage, or obsolescence, can avoid paying duties on goods that never reach the consumer.

Inverted tariff savings. When a manufacturer in an FTZ produces a finished product that has a lower HTS duty rate than its foreign-sourced components, the manufacturer can elect to pay the lower finished-product rate on the foreign inputs. Duty is not owed on the U.S. value added (labor, overhead, profit) attributable to zone production. This benefit requires FTZ Board approval for manufacturing activity.

Merchandise Processing Fee (MPF) reduction. Zone users can file a single customs entry for all goods shipped from the zone in a consecutive seven-day period, instead of one entry per shipment. MPF is charged at 0.3464% of total estimated value, with a minimum of $27.23 and a maximum of $528.33 per entry. Consolidating shipments into weekly entries can save substantially on both MPF and brokerage fees.

Benefit	How It Works	Best For
Duty deferral	Pay duties only when goods enter U.S. commerce	Companies holding inventory
Duty elimination (re-export)	No duties on goods exported from FTZ	Import/export operations
Inverted tariff	Pay lower finished-product rate on components	Manufacturers with high-duty inputs
Scrap/waste elimination	No duties on destroyed goods	Manufacturing with yield loss
Weekly entry	Consolidate entries, reduce MPF and broker fees	High-frequency importers

How Do FTZs Interact with Current Tariff Programs?

The relationship between FTZs and the current tariff environment involves important nuances.

Section 232, Section 301, and Section 122 tariffs. Goods subject to these additional tariff programs require "privileged foreign status" when admitted to an FTZ. This means the goods' tariff classification and applicable duty rates are locked in at the time of admission, rather than being deferred. The practical effect is that FTZs do not eliminate these special tariffs, but they still provide inventory positioning, cash flow benefits, and MPF savings.

Inverted tariff limitations. FTZ Board regulations and specific trade measures may restrict inverted tariff benefits for certain product categories, particularly those subject to Section 232 or Section 301 tariffs. Importers should verify eligibility for specific products before assuming inverted tariff savings apply.

Strategic flexibility. Even with limitations, FTZs provide strategic value during tariff volatility. If a new trade agreement reduces duty rates, importers can wait to withdraw goods from the zone until the lower rate takes effect, effectively timing their customs entry to capture the most favorable rates.

How Do You Set Up an FTZ Operation?

There are three primary types of FTZ designations:

General-purpose zones. Multi-user facilities, typically in industrial parks or warehouse complexes, where multiple companies can lease space. Lower upfront costs since the infrastructure is already activated. Best for small to mid-sized importers, distributors, and third-party logistics providers.

Subzones (usage-driven sites). Designated for a specific company at a specific location. Requires an application to the FTZ Board. Best for manufacturers with dedicated facilities and production-specific FTZ needs.

The setup process involves four key steps: submitting a written statement of need to the local FTZ grantee, applying to the FTZ Board through the grantee and CBP, submitting a production application (if manufacturing is involved), and requesting activation from local CBP. The timeline varies from one to six months depending on location, volume, product type, and complexity.

FAQ

How much does it cost to operate in a Foreign Trade Zone?

Costs include application fees, annual assessments, and operating fees. General-purpose zone space is often the most cost-effective entry point, with costs similar to standard warehouse leasing plus zone-specific fees. Companies should weigh setup costs against projected duty savings, which can be substantial for high-volume importers or manufacturers with inverted tariff opportunities.

Can any product be admitted into an FTZ?

Any merchandise that is not prohibited from entry into the United States may generally be admitted. Manufacturing and processing activities that change a product's tariff classification require separate FTZ Board approval. Retail trade within zones is prohibited. Import licenses or permits from other government agencies may still be required.

Is an FTZ the same as a bonded warehouse?

No. FTZs and bonded warehouses serve different purposes. FTZs allow manufacturing and processing, have no storage time limit, permit inverted tariff benefits, and allow weekly entry filing. Bonded warehouses limit storage to five years, do not permit manufacturing, and assess duty on the full value including damaged goods and scrap.

How does an FTZ help with IEEPA tariff refunds?

FTZs do not directly affect the IEEPA refund process. However, for companies reassessing their supply chain strategies in the post-IEEPA tariff environment, establishing an FTZ operation can provide structural duty savings going forward, complementing any refund recoveries from the CAPE process.

Can GingerControl help evaluate whether an FTZ strategy makes sense?
