Input-output norms set permissible aluminium inputs for export manufacture and require imported inputs to match declared use.

Standard Input Output norms permit aluminium scrap or aluminium/alloy ingot as inputs for manufacture of aluminium cast articles for export, with specified input to product proportions; amendments to the Table are effected by public notice. Applicants must determine and document the proportions of inputs used in manufacture and ensure imported goods match the goods actually used or required in the export product.
