Origin determination rules require tariff classification changes or qualifying value content thresholds to establish originating status. Product origin under the CEPA Annexure is determined by product specific rules adjacent to HS headings: goods must be wholly obtained, or satisfy a specified change in tariff classification from non-originating materials, and where indicated meet a qualifying value content. The Annexure follows the Harmonized System and, for textiles, Appendix A prescribes mandatory manufacturing processes (e.g., spinning, weaving, dyeing/printing, making up) with dyeing/printing sometimes requiring additional finishing operations to confer originating status.
