Input-output norms for chemical imports govern allowed input composition and require verification of use in export products.

Standard input-output norms prescribe the permitted composition and weight proportions of inputs for manufacture of Activated Polydimethyl Siloxane (Simethicone USP); the norm has been suspended by public notice. Applicants must ensure imported inputs match declared goods and are actually used or required in the export product, while authorities determine acceptable input proportions for resultant products.
