Input-output norms for Cefuroxime Sterile Sodium define the permissible import input and required manufacturing linkage. Standard Input-Output Norms under the Foreign Trade Policy prescribe the import entitlement for the export product Cefuroxime Sterile Sodium. The norm allows export of 1 kg of Cefuroxime Sterile Sodium against import of 1.04 kg of Cefuroxime Acid as the corresponding input. SION determines the proportion of inputs that may be used or required in manufacture, and applicants must ensure that the goods sought for import and actually imported are those used or required in the export product.
