Crank shaft input-output norms require imported steel inputs to match those actually used in the exported crank shaft product. The norm specifies a finished crank shaft weight of 1.0 kg and input of non-alloy/alloy steel rods at 1.60 kg per kg of export product, and requires determination of proportions of inputs used in manufacture while obliging applicants to ensure imported goods are those actually used or required in the export product.
