<h1>Input-output norms require imported raw materials to match actual usage for silver-bearing copper export manufacturing compliance.</h1> Input-output norms for Silver Bearing Copper Strip/Sheets/Foil (SION C1188) set permissible inputs - including copper scrap, copper wire bar, and specified-purity silver bullion/ingots - with required input quantities per kilogram of exportable product. The SION was administratively suspended and previously substituted by public notice. Applicants must ensure imported inputs are those actually used or required in manufacture and that proportions of inputs conform to the specified norms for verification and entitlement purposes.
