Standard input-output norms for fully threaded rods require specified input proportions and proof imports are used in exports.

Standard input-output norms prescribe permitted input proportions for manufacture of galvanised fully threaded rods, specifying primary threaded rod input, additional bars and rods in a higher proportion, and zinc input only when galvanisation of threaded rods is involved; applicants must ensure imported materials correspond to listed inputs and are actually used in the exported product, with proportions determinable and verifiable under the schedule.
