Preferential Origin is the country of origin of a good determined under the rules of origin of a specific free trade agreement or unilateral preference program. Goods that satisfy preferential origin rules qualify for reduced or zero duty rates under that program — but the determination is separate from non-preferential origin used for marking, Section 301, and AD/CVD.
Preferential origin is governed by the product-specific rules of origin (PSROs) of each agreement. Most agreements use one or more of the following:
- Wholly obtained or produced test (raw materials, agricultural products)
- Tariff shift rule (change in HTS classification)
- Regional value content threshold
- Specific processing requirements (e.g., yarn-forward for textiles)
- Combinations of the above
Each FTA has its own PSROs, certification requirements, and documentation rules:
| Agreement | Certification | Verification |
|---|---|---|
| USMCA | Certification of Origin | CBP origin verifications |
| KORUS | Certification of Origin (importer/exporter/producer) | Self-certification |
| CAFTA-DR | Certification of Origin | Self-certification |
| GSP | GSP Form A (where required) | 35% value-added rule |
| AGOA | Combined Form A / textile visa | Yarn-forward for apparel |
Accumulation rules allow inputs originating in one FTA party to be treated as originating when used in another party. De minimis rules forgive small percentages of non-originating materials that fail tariff shift.
To claim preferential treatment, the importer must possess a valid certification at the time of claim, be prepared to support the claim with the producer's bill of materials and cost data, and respond to CBP verification within the prescribed timeframe. False preference claims trigger duty recovery plus penalties under 19 U.S.C. § 1592.
