<h1>Input-output norms under foreign trade rules govern allowable import inputs and require matching use in export products.</h1> Standard Input-Output Norms under the Foreign Trade Policy set quantitative input weights for manufacture of ferro chrome/charge chrome and related engineering products, including specified feedstocks, carbon sources, electrodes, furnace oils and lubricants, with a captive power plant note. The schedules provide that the authority determines allowable input proportions, and applicants must ensure imported goods are those actually used or required in the export product for compliance with the prescribed norms.
