Input-output norms require importers to restrict imports to inputs actually used in manufacture for export.

Standardised input-output norms prescribe permissible raw materials and their usage proportions for manufacture of cefadroxil, listing specific chemical precursors and reagent weight ratios per kilogram of finished product to guide import authorisations. A schedule requires determination of the proportion of inputs used in manufacture and obliges applicants to ensure that imported goods are those actually used in the export product, creating a compliance duty to align imports with production requirements.
