Input-output norms for cable manufacture require imported inputs to match actual use in the certified export product.

Standard Input-Output Norms prescribe the material composition and constituent input proportions for manufacture of PVC three-core flat cable, listing copper wire rods, PVC compound and its subcomponents. The norms require determination of allowable input proportions consistent with the manufacturing process, and mandate that applicants ensure imported goods are those used or required in the certified export product and conform to the prescribed bill of materials.
