Standard input-output norms require imported feedstocks to match declared use and be used in specified export products.

Standard Input-Output Norms prescribe allowable proportions and conversion of chemical inputs for export manufacture, exemplified by Light Liquid Paraffin/Light white oil/Light Mineral Oil entries showing 1 kg yielding 1.06 kg base oil and 0.05 kg isopropyl alcohol, and require applicants to ensure that imported goods are those used or required in the declared export product.
