<h1>Input-Output norms for auto-transformer manufacturing specify permitted inputs and importer responsibility for matching imports to export use.</h1> Input-Output norms prescribe permissible inputs and quantitative consumption rates for manufacture of three-phase auto transformers above 63000 KVA up to 100000 KVA, listing CRGO steel laminations, copper winding materials, transformer oil or base stock, phenolic resin bonded paper, pre-compressed press board, press board moulding and motorised tapchangers with specified kgs-per-KVA/KW or net-to-net treatment. Applicants must ensure imported goods are those used or required in the export product and accept that the proportion of various inputs will be determined against the resultant product.
