Input-output norms require matching imported inputs to manufacturing composition to ensure export compliance and verification. Standardised input-output norms under the Foreign Trade Policy prescribe constituent inputs and proportions for manufacturing polyurethane resin H565 and note insertion by public notice. A schedule governs determination of permissible input proportions for resultant products, and applicants importing inputs must ensure imported goods correspond to those used or required in the export product, creating an export compliance and import-verification obligation.
