Input-output norms for coated cold-rolled steel define allowable inputs, substitute ratios, and conditional import allowances. Prescribed input-output norms for Cold Rolled Un Galvanised Colour Coated Non Alloy Steel Sheets specify permitted primary inputs (cold rolled or hot rolled strips/wide coils), multiplicative substitute ratios for alternate steel inputs, quantified ancillary inputs (paints, rolls, oils, packing, guard film, applicator rolls) with some items conditional on importing the hot rolled variant, and require applicants to ensure imported goods are those used or required in the export product.
