Input-output norms require imported materials to match prescribed compositions for rubber polished brakes and verify use in exports.

Standard Input-Output Norms for Rubber Polished brakes (A1712) set out required input categories-natural or synthetic rubber, precipitated silica, rubber chemicals (including accelerators, antioxidants and titanium dioxide), zinc oxide and miscellaneous processing chemicals-and allocate proportions to each. The entry is suspended by public notice. Applicants importing under these norms must ensure imported goods match the prescribed inputs and are actually used or required in the manufacture of the exported product, with verification responsibility on the applicant.
