<h1>Public notice suspends standard input-output norms for gun metal valves; mandates conversion ratio and verification for exports</h1> Standard input-output norms for a gun metal valves item under engineering products have been suspended by a public notice. The schedule records a conversion showing 1 kg of gun metal valves corresponding to 1.075 kg of gun metal scrap. The regime requires determination of allowable input proportions for manufacture of resultant products, and directs applicants to ensure that imported goods match those used or required in the exported product. Compliance with the prescribed input-output relationship and verification of actual use in export production is mandated.
