Input-output norms define permissible input proportions for cotton core spun yarn and require import-use verification.

Standard Input Output Norms under the Foreign Trade Policy set material-content proportions for Combed Cotton Core Spun Yarn/sewing thread: raw cotton at 1.22 kg per kg of export product and relevant core yarn at 1.01 kg per kg. The Schedules require determination of input proportions for manufacture, and applicants must ensure that imported goods are those actually used or required in the export product.
