<h1>Standard Input Output Norms govern allowable inputs for hot metal/pig iron and require verification of imported inputs' use in exports.</h1> Prescribed Standard Input Output Norms specify the allowable inputs and their relative proportions for manufacturing Hot Metal/Pig Iron, listing iron ore, metallurgical coke (with variants for PCI use), coking coal (with PCI variants), PCI coal for injection systems, coke breeze, limestone, dunite, and certain miscellaneous items. These norms serve as the eligibility criteria for import entitlement and require applicants to ensure that imported goods are those actually used or required in the exported product; the schedules are the reference for determining permissible input proportions for compliance assessment.
