Standard Input Output norms require imported aluminium tube inputs to match prescribed manufacturing proportions and applicant compliance.

Standard Input-Output norms prescribe input weight metrics for Aluminium Redrawn Alloy Tubes/Pipes and Aluminium Extruded Hollow Alloy Tubes/Pipes and the schedule determines permissible proportions of inputs in manufacture; applicants must ensure imported goods are those actually used or required in the export product and comply with the prescribed manufacturing proportions.
