Standard Input-Output norms govern permitted inputs for aluminium foil exports, with conditional allowances for printed or reinforced products. Standard Input-Output Norms specify component inputs and their weights for commercial-grade aluminium foil for export, listing aluminium foil stock, polymer granules, solvent-soluble dyestuff, synthetic resin, and adhesives or reels. Solvent-soluble dyestuff is permitted only when the export product is printed; polymer granules, synthetic resin, and dyestuff are permitted only when the export product includes reinforcing material. Applicants must ensure imported inputs are those used or required in the export product and proportions may be determined and verified against the schedule.
