<h1>Standard input-output norms removed; importers must ensure imported inputs match those required for the exported products.</h1> Deletion of the standard input-output norms for Chemical & Allied Products (SION A2793) eliminates the prescribed schedules yet the schedules governed determination of permissible proportions of inputs in manufacture, and applicants must ensure imported goods are those used or required in the export product, verifying that imported materials match the use-or-requirement for declared exported goods.
