<h1>Match imported materials to declared export product and required input proportions to satisfy proportional input determinations for export eligibility</h1> Where proportional input determinations apply, authorities will establish the share of various inputs permissible or required for producing different resultant products; applicants must ensure that the goods they seek to import and actually import correspond to inputs used or required in the declared export product. Compliance requires matching imported materials to the intended export manufacturing process and product composition to satisfy validation of input proportions for export eligibility.
