Foreign Trade Zone (FTZ) FAQ
Answers to common questions about Foreign Trade Zones, duty savings, the application process, and compliance requirements.
FTZ Basics
What is a Foreign Trade Zone?
A Foreign Trade Zone (FTZ) is a designated, restricted-access site within or near a U.S. port of entry where foreign and domestic merchandise can be admitted without formal customs entry or payment of duties. FTZs are licensed by the Foreign Trade Zones Board (composed of the Secretary of Commerce and Secretary of the Treasury) and supervised by U.S. Customs and Border Protection under 19 U.S.C. 81a-81u and 19 CFR Part 146. Companies operating in an FTZ can store, assemble, manufacture, and process goods before deciding whether to enter them into U.S. commerce or re-export them.
What are the main benefits of using an FTZ?
The primary benefits of operating in a Foreign Trade Zone include duty deferral (no duties are owed until goods enter U.S. customs territory), inverted tariff savings (paying the lower finished-product duty rate instead of higher component rates), Merchandise Processing Fee (MPF) reduction on exports, quota avoidance (goods in zones are not subject to quota restrictions), and exemption from state and local ad valorem taxes on goods destined for export. These benefits can significantly reduce the total landed cost of imported goods, particularly for manufacturers with high-duty raw materials.
What is the difference between a general-purpose zone and a subzone?
A general-purpose zone is a multi-use site that serves multiple companies and industries, typically offering warehouse space, open land, and public services within a defined area near a port of entry. A subzone is a special-purpose site designated for a specific company whose operations cannot be accommodated within an existing general-purpose zone. Subzones can be located within the same port area or outside the service area and are subject to the same FTZ regulations. Under the Alternative Site Framework (ASF), companies can also use usage-driven sites, which are designated through a streamlined minor boundary modification (MBM) process with no application fee and a 30-day approval timeline.
Duty Savings
How does duty deferral work in an FTZ?
Duty deferral means that customs duties and federal excise taxes are not assessed on foreign merchandise while it remains within the FTZ. Duties are only owed when goods are formally entered into U.S. customs territory for domestic consumption. This allows companies to store inventory indefinitely without tying up cash in duty payments. If goods are re-exported from the zone, no U.S. duties are ever owed. Companies also have the choice of paying duties based on either the original imported materials or the finished product, whichever results in a lower duty rate.
What are inverted tariff savings?
Inverted tariff savings occur when the duty rate on a finished product is lower than the duty rates on its imported raw materials or components. In an FTZ with production authority, a company can import high-duty components, manufacture them into a finished product within the zone, and then elect to pay the lower finished-product duty rate when entering the goods into U.S. commerce. For example, if imported LED panels carry a 6% duty but the finished lighting fixture carries a 3.5% duty, the company saves 2.5% on the value of those components by manufacturing in the zone and choosing the finished-product rate.
How does an FTZ reduce Merchandise Processing Fees (MPF)?
When foreign merchandise is admitted to an FTZ and subsequently exported, the Merchandise Processing Fee (normally 0.3464% of the entered value, with a minimum of $31.67 and a maximum of $614.35 per entry) does not apply. Additionally, when goods are entered from an FTZ into U.S. customs territory, entries can be consolidated on a weekly basis rather than per-shipment, which means the MPF maximum cap applies once per weekly entry rather than once per individual shipment. This consolidation alone can save thousands of dollars annually for high-volume importers.
Can FTZs provide relief from quota restrictions?
Yes. Goods stored in a Foreign Trade Zone are not considered to have entered U.S. customs territory, so they are not subject to quota limits while in the zone. This allows importers to bring merchandise into the zone and hold it until a quota opens, or to process it within the zone for re-export without quota constraints. However, when goods are eventually entered into U.S. commerce, applicable quotas will apply at that point. This flexibility is particularly valuable for industries like textiles and apparel where quotas can restrict import timing.
Getting Started
What is the Alternative Site Framework (ASF) and how does it simplify FTZ designation?
The Alternative Site Framework (ASF) is a modernized approach to FTZ designation that replaced the traditional site-by-site approval process for many zones. Under ASF, a zone's service area is pre-approved, and individual companies can be designated as usage-driven sites through a minor boundary modification (MBM) process. The MBM process requires no application fee, no public comment period, and decisions are typically made within 30 days. Companies need to provide basic information including the site address, a company and activity summary, right to use the site, a map, and CBP concurrence. Usage-driven sites are subject to a three-year sunset provision, meaning the company must demonstrate actual FTZ activity to maintain designation.
How long does it take to get FTZ designation?
Timeline varies depending on the type of designation. Under the Alternative Site Framework (ASF), a usage-driven site designation through the minor boundary modification process typically takes about 30 days. For a Traditional Site Framework (TSF) subzone application, the process takes significantly longer due to the required public comment period and FTZ Board review, typically 6 to 12 months. Production authority requests via the notification process follow a standard 120-day review timeline from submission, including a 40-day public comment period.
What does a production authority notification involve?
Production authority is required for any manufacturing or processing activity within an FTZ that results in a change in the Harmonized Tariff Schedule (HTS) classification at the six-digit level. To request production authority, a company submits a Production Notification to the FTZ Board that includes a list of foreign-status components and finished products with their HTS codes and written descriptions. The notification undergoes a 40-day public comment period, followed by FTZ Board review with a standard 120-day decision timeline. Companies that need to begin operations sooner can request interim production authority, which requires CBP concurrence and an explanation of the time-sensitive need.
What are the costs of FTZ designation?
Costs vary by designation type. Under the ASF minor boundary modification process, there is no application fee to the FTZ Board. Traditional Site Framework subzone applications carry fees of $4,000 to $6,500 depending on the number of products involved. Beyond application fees, companies should budget for ongoing costs including CBP activation fees, inventory control and recordkeeping system implementation, compliance staffing, security infrastructure, and annual reporting requirements. The grantee (the entity that manages the zone) may also charge annual fees or per-transaction charges. A thorough cost-benefit analysis should weigh these costs against projected duty savings.
Cost-Benefit Analysis
How do I determine if an FTZ makes sense for my operation?
An FTZ cost-benefit analysis (CBA) compares projected duty savings against the costs of zone designation and operation. Key factors include your annual import volume and duty spend, the duty rates on your imported components versus finished products (to identify inverted tariff opportunities), the percentage of goods re-exported (which benefit from full duty elimination and MPF savings), and the volume of weekly entries (which determines MPF consolidation savings). Generally, companies with annual duty payments exceeding $100,000, significant re-export activity, or clear inverted tariff situations are strong FTZ candidates. Impor's FTZ Evaluation skill can analyze your entry data automatically to quantify these savings.
What data do I need for an FTZ cost-benefit analysis?
A comprehensive FTZ cost-benefit analysis requires entry summary data (CBP Form 7501) including HTS codes, duty rates, entered values, and quantities for each line item; a bill of materials (BOM) showing foreign versus domestic content in manufactured products; information about your re-export volume and destinations; current MPF payments; and your supply chain timeline showing how long goods are held before entering U.S. commerce. Historical data covering at least 12 months is recommended to account for seasonal variations. Impor can process this data directly from uploaded entry packages, spreadsheets, or PDF documents, eliminating the need for manual data compilation.
Compliance
What inventory control requirements apply in an FTZ?
FTZ operators must maintain a comprehensive inventory control and recordkeeping system as required by 19 CFR 146.22. This system must track all merchandise movements into, within, and out of the zone using Zone Lot Numbers (ZLN) and Unique Identifier Numbers (UIN) such as part numbers or SKUs. Acceptable inventory methods include FIFO (First In, First Out) and specific identification. Operators must maintain an English-language procedures manual, conduct physical inventories, submit annual reconciliation reports within 90 days of year-end, and provide CBP examination access at all times. The FTZ Board also conducts periodic monitoring visits (typically half-day to full-day site reviews) to verify compliance and scope of authority.
What is the difference between privileged and nonprivileged foreign status?
Privileged foreign status (PFS) locks in the duty rate and classification of merchandise at the time it is admitted to the FTZ. This protects the importer from future tariff increases; the rate at admission applies regardless of when the goods eventually enter U.S. commerce. Nonprivileged foreign status (NPFS) means duty rates and classification are determined at the time of entry into customs territory, based on whatever rates are in effect at that time. NPFS is the default status for foreign merchandise admitted to a zone. PFS must be specifically requested and is advantageous when tariff rates are expected to rise. Once privileged status is established, it cannot be changed. Both statuses allow goods to be exported from the zone duty-free, except for shipments to NAFTA/USMCA partner countries which may trigger special duty provisions.
