Substantial Transformation and Non-Preferential Origin
For most purposes the origin of an imported article is determined by the substantial transformation test: whether processing in a country produced a new and different article of commerce with a name, character or use distinct from that of the materials it came from. Codified tariff-shift rules in 19 CFR Part 102 govern marking for certain agreement partners and all textile goods, and preferential origin is governed by the rule of origin in the agreement itself.
