Input-output norms for transformers specify permitted input components and exclusions when oil or tank are not exported.

The policy prescribes Input-Output norms for copper-wound, three-phase oil-cooled transformers in a defined capacity band, listing permitted inputs (CRGO laminations, copper winding materials, transformer oil or oil base stock, press boards, phenolic resin bonded paper, tap changers, and moulded components) and specifying measurement on a net-to-net basis. It requires applicants to ensure imported goods match inputs used in the exported product and disallows entitlement to transformer oil or oil base stock when transformers are exported without the metal tank and transformer oil.
