Standard input-output norms for phosphor bronze exports require specified input proportions and verification of import use.

Standard Input-Output Norms set permissible inputs for phosphor bronze strips and specify kilogram-per-kilogram input-to-export product ratios for phosphor bronze scrap, copper sources and tin ingots. The schedules determine allowable proportions of inputs for manufacture and impose a verification obligation that imported goods are those actually used or required in the export product.
