Cumulation, de minimis, and minimal operations
What the exam tests
This domain tests three relief mechanisms and their limits. Cumulation treats qualifying materials or processing in a partner country as originating. De minimis disregards small amounts of non-originating material that fail the PSR. Minimal operations are insufficient to confer origin even if they change the goods physically.
Core rules
- Bilateral cumulation: materials from one party are treated as originating in the other when the agreement allows.
- Diagonal or regional cumulation: several countries pool origin, usually with proof and transportation conditions.
- De minimis: value or weight threshold, often 10% of FOB or product weight, applies only to non-originating materials that do not undergo the required shift; it does not cure a failed RVC unless the rule says so.
- Minimal operations: packaging, labeling, simple mixing, sorting, or repacking cannot be the sole basis for origin.
Worked example
A plastic article of HS 3926 uses a non-originating cap also classified in 3926 at 6% of FOB. The CTH rule fails for that cap. If the agreement has a 10% de minimis for non-originating materials that fail the PSR, the cap may be disregarded and the article qualifies. If the cap were 12% of FOB, de minimis would not save the claim.
Traps
Applying de minimis to the whole product value when the rule is weight-based; using cumulation without supplier proof; confusing cumulation with de minimis; treating simple repacking as substantial transformation.
