Standard input-output norms govern permissible inputs for hydroxylamine sulphate manufacture and require import-export use verification.

Standard input-output norms prescribe permitted inputs and proportions for manufacture of Hydroxylamine Sulphate via the caustic soda route, listing feedstocks and input weights; the Hydroxylamine Sulphate entry is suspended. Applicants must ensure imported goods are those used or required in the export product, and proportions of inputs must be determined and verified for conformity with the norms.
