Input-output norms for exports require specified material proportions and matching imports to goods used in production.

Standard input-output norms prescribe material-consumption ratios for Polypropylene Insulated Ware/Casserole (H227), identifying PP granules and glass wool insulation as principal inputs. Applicants must determine and apply required input proportions for manufacture and ensure imported goods correspond to those used in the export product, so declared imports match inputs physically consumed to meet FTP compliance.
