Standard input-output norms for steel tubes require verified input proportions and import of only authorized inputs for export production.

Standard Input-Output norms set permissible input-to-output ratios for manufacture of exported Single/Double Walled Steel Tubes (copper coated), specifying required quantities of CRCA strips and electrolytic-grade copper anodes per unit of export product, and requiring applicants to import only goods used or required in the export product with verification that actual consumption conforms to declared proportions.
