Input-output norms require specified input ratios for Di-Octyl Phthalate and mandate verification that imported inputs serve export production. Standard input-output norms under SION A1303 set permissible consumption ratios for Di Octyl Phthalate (DOP) and its inputs, noting substitutions to input quantities by public notice. The regime requires authorities to determine allowed input proportions for manufacture of the resultant product and places a compliance obligation on applicants to ensure imported goods are those used or required in the export product.
