<h1>Input-output norms govern permissible chemical inputs and require import-use parity for export product compliance.</h1> Standard input-output norms under the Foreign Trade Policy govern import and use of chemical inputs for the Salbutamol sulphate intermediate. A table specifies the intermediate and constituent inputs with prescribed quantities. The schedule requires determination of permissible input proportions for manufacture and mandates that applicants ensure imported goods are those used or required in the declared export product to satisfy FTP compliance.
