Input-output norms require importers to verify that imported inputs match the goods used in declared export production.

The Foreign Trade Policy's Standard Input-Output Norms specify quantitative inputs for chemical products and record suspensions by trade notice. Applicants must determine permissible input proportions for manufacture and must verify that imported goods are the same goods used or required in the declared export product, creating an obligation to match imports to export production requirements and adhere to any listed suspensions.
