De minimis thresholds determine when non-originating inputs still allow preferential origin, affecting valuation for local value added requirements. A De Minimis provision allows goods failing the tariff classification change in final production to be treated as originating where limited non-originating inputs are used and all other origin criteria are satisfied. For non-textile goods the measure is by value relative to the FOB value; for textile goods (HS chapters 50-63) the measure is by weight of basic textile materials. The value of such non-originating materials must be included in the calculation of any applicable local value added content requirement for the good.
