Standard input-output norms require imported inputs to match declared usage in export product manufacturing and documentation.

Standard input-output norms specify component proportions for Bonding Gum (90% solid content), listing natural and synthetic rubber, carbon black, zinc oxide, rubber chemicals (with antioxidant limited to 50% of rubber chemicals) and miscellaneous chemicals; applicants must ensure imported goods correspond to inputs used or required in the export product and determine allowable input proportions for each resultant product.
