Import and origin requirements
CBP administers customs requirements including origin marking for imported articles. Marking origin, preferential tariff eligibility and domestic-origin advertising claims require distinct analyses.
Customs and Border Protection is represented in this collection through the specific publications listed below. Begin with the product, activity and responsible party identified by the source. A reference to an agency does not establish that every product in an industry follows the same pathway. Scope, definitions, exceptions and the status of an adopted technical document can change the conclusion.
Use the original publication to establish the requirement, then connect it to the actual model, configuration, process or transaction. Keep source dates separate from effective and compliance dates. Where several agencies are relevant, preserve a distinct conclusion for each framework. A test report, registration, approval, certification and voluntary program claim should be assessed for the precise object and conditions they cover.

Federal regulationCBP
19 CFR Part 134
Part 134 implements country of origin marking requirements for imported articles. The analysis concerns the origin of the article, the ultimate purchaser and the form in which the article reaches that purchaser. Marking, tariff treatment and advertising claims are related but distinct questions; a customs marking conclusion should not be reused automatically as a broader domestic-origin marketing claim.
Federal regulationEPA / CBP
TSCA section 13; 19 CFR 12.118–12.127; EPA import policy at 40 CFR 707.20
TSCA import certification connects a shipment entering the United States to the chemical requirements that apply to it. The importer or authorized agent provides a positive or negative certification as appropriate. The declaration rests on the substance, use and applicable restrictions; it does not replace a new chemical review, an exemption determination or a product-specific regulatory obligation.
