<h1>Input-output norms require imported inputs to match declared use in manufacture, ensuring compliance with FTP export controls.</h1> Standard input-output norms for fibreglass insulation products list permitted inputs and their specified quantities or bases and include a suspension reference. Applicants must ensure that the proportions of inputs declared and imported match those actually used or required in the manufacture of the export product; import clearances depend on such verification and compliance with the specified input proportions and export order requirements.
