<h1>Input-output norms govern allowable imported components for manufacture and require proof of actual use in export products.</h1> Input-Output Norms prescribe specific input quantities and proportions for manufacture of MR-16 halogen lamps, listing components and their weights/counts per 1,000 lamps, and operate as the basis for admissible imports for export manufacture. The instrument was suspended by public notice and requires applicants to ensure imported goods are those actually used in the export product; authorities determine applicable input proportions for resultant products.
