Input-output norms for aluminium household articles: prescribed input proportions and anodized purity requirements govern permissible imports for export manufacture. Prescribes Input-Output Norms for aluminium table, kitchen and household articles, listing allowable input categories (aluminium scrap, ingot, sheet/coils) with specified input proportions per unit of export product and a minimum purity requirement for anodized inputs. The rule obliges determination of input proportions in manufacture and mandates that applicants ensure imported goods are those actually used or required in the export product to maintain compliance and traceability.
