The core difference
| Foreign-trade zone | Duty drawback | |
|---|---|---|
| When duty is handled | Not paid until goods enter U.S. commerce | Paid at import, refunded later |
| Goods that are exported | No U.S. duty owed | Up to 99% of duty refunded |
| Goods sold in the U.S. | Duty paid at entry, possibly at a lower finished-good rate | No refund |
| Cash flow | Duty deferred while goods sit in the zone | Cash tied up until the claim is paid |
| Setup | Zone or subzone activation, and CBP-compliant inventory control | Claim filing, with privileges for accelerated payment |
| Main rules | 19 CFR Part 146 and 15 CFR Part 400 | 19 U.S.C. 1313 and 19 CFR Part 190 |
When a zone saves more
- Mixed destinations. Goods that will be split between export and domestic sale can wait in the zone until the destination is known. Exports never pay duty.
- Inverted tariffs. With production authority from the Foreign-Trade Zones Board, a manufacturer can pay duty at the finished product's rate when it is lower than the rate on imported components, using nonprivileged foreign status.
- Frequent shipments. Weekly entry consolidates a week of withdrawals into one entry, which lowers merchandise processing fees. See FTZ weekly entry.
- Deferral. Duty on inventory is not paid until it leaves, which frees working capital.
When drawback saves more
- Duty is already paid. Drawback recovers duty on imports that entered customs territory normally and were later exported or destroyed, including historical imports within the claim window.
- No zone footprint. Drawback needs records and claims, not a designated site.
- Substitution. Drawback can pay on exports of commercially interchangeable goods, not only the exact imported units, under the substitution provisions of 19 U.S.C. 1313.
Using both
The programs are not mutually exclusive.
- Duty-paid merchandise transferred into a zone for exportation, storage, or destruction can be treated as exported for drawback purposes, under 19 CFR Part 190, Subpart R.
- Merchandise entered for consumption from a zone, with duty paid, is regularly entered and can support a drawback claim if it is later exported, subject to the usual drawback requirements.
- Many companies run a zone at one site and drawback for exports from facilities outside it.
The right mix depends on where inventory sits, how much of it is exported, and which tariffs apply. Additional duties such as Section 232 and Section 301 affect both programs and can require specific zone status on admission. Our Chapter 99 tariff stack guide covers that interaction.
