<h1>Foreign trade policy sets precise input-output norms and required matching imports for manufacturing blank audio cassettes</h1> Input-output norms specify permissible inputs and quantities for manufacture of blank audio cassettes under the foreign trade policy, listing raw materials (magnetic tape, leader tape, polyester film), metal and plastic parts (pressings, liners, hubs, shells, screws), labels, inlay covers, cartons, tapes and packaging with precise unit counts and weights per production batch. The schedule requires determination of proportions of inputs for each resultant product and mandates that imported goods correspond to those actually used or required in the exported product; nonconforming imports may be subject to suspension or restriction under the policy.
