Standard Input-Output Norms require prescribed input proportions and that imported inputs be used in the exported product manufacturing.

Standard Input-Output Norms set prescribed input-to-output proportions for engineering products (including Pen Caps C750 and specified brass scrap and steel tube content allowances) and require determination and verification that imported goods are the inputs actually used or required in the manufacture of the exported product; applicants must ensure imports match declared manufacturing inputs.
