Input-output norms for chemical exports require specified input proportions and verification that imported inputs are used in production.

Standard Input-Output Norms for Potassium Cyanide (A1152) set specified input proportions including associated ammonia and potassium hydroxide quantities; the SION entry is suspended by Public Notice No. 03/2024-25. Applicants must determine and verify the proportion of inputs used in the manufacture of export products and ensure that imported goods are those required and actually used in the export product.
