Where General Note 25(o), HTSUS, sets forth a rule that specifies a regional value content test for a good, the regional value content of such good must be calculated, at the choice of the person claiming the preferential tariff treatment for such good, on the basis of the build-down method or the build-up method described in paragraphs (b) and (c) of this section, unless otherwise specified in General Note 25(o), HTSUS.\n(b) Build-down method.
