<h1>Input-output norms require specified conversion factors for metal ingots and scraps when determining import requirements for export products.</h1> FTP prescribes input-output norms for alloy constituents, setting conversion factors for metal inputs used in export products-distinguishing ingot and scrap forms and allowing higher input for scrap to reflect material differences. Applicants must ensure imported goods correspond to those used in manufacture; permissible input proportions are determined by the Schedule and compliance depends on demonstrating that imported goods are those actually used in the export product.
