Standard input-output norms require import verification to ensure chemical inputs match declared export product use.

Standard input-output norms specify permitted inputs and per-unit quantities for manufacture of Allura Red (Food Red 17). The list identifies constituent chemicals and quantities per 1 kg finished dye. A schedule requires determination of permissible input proportions for resultant products and obliges applicants to ensure imported goods are those used or required in the declared export product, enabling authorities to verify conformity with prescribed norms.
