Standard input-output norms define permissible inputs for fire-resistant synthetic rubber sheet exports, requiring imported materials to match declared usage.

Standard Input-Output Norms set specific constituent materials and permitted quantities per kilogram for manufacture of Synthetic Rubber Sheet (Fire Resistant), including poly chloroprene rubber, precipitated silica and hard clay, zinc oxide, carbon black, rubber chemicals, miscellaneous chemicals, HDPE and polypropylene. Applicants must ensure imported goods are those used or required in the export product, and authorities will determine and verify proportions of inputs used against the prescribed norms.
