<h1>Input-output norms set permitted textile inputs for children snow suits and require import-use conformity for exports.</h1> Standard input-output norms under SION J351 specify permitted inputs and proportions for children's snow suits (resultant product one unit), listing required fabric quantities for outer fabric and lining. The schedule mandates determination of input proportions for manufacture and requires applicants to ensure imported goods are those used or required in the export product, making import-use verification a compliance requirement under the Foreign Trade Policy.
