Input-output norms for heat-resistant rubber require imported inputs to match prescribed component proportions and intended export use.

Standard input-output norms prescribe precise weight proportions of constituent inputs per kilogram of finished heat resistant rubber tension tape and cut rubber thread, listing natural and synthetic rubbers, activators, antioxidants, accelerators, peptisizers, retarders, vulcanising agents, fillers, co-activators and pigments. Applicants must ensure imported goods match those used or required in the export product and compliance is assessed by reference to these prescribed proportions.
