Preferential duties are reduced or zero customs duty rates granted to eligible imported goods under a free trade agreement, trade preference programme, or special customs arrangement. To qualify, goods usually must meet rules of origin, documentation, and direct shipment requirements. Preferential duties can lower landed costs for importers, but they must be claimed correctly with supporting records such as certificates of origin, supplier declarations, or origin statements.
Preferential duties are reduced or zero tariff rates available to goods that qualify under a free trade agreement (FTA) or preferential trade program. They are lower than the standard most-favored-nation (MFN) duty rate normally applied to imports from non-FTA countries.
How to Access Preferential Duties
- Verify the product qualifies under the FTA rules of origin
- Obtain or prepare the required certificate of origin or self-certification
- Claim the FTA preference on the customs entry
- Maintain documentation for five years for potential CBP audits
