Standard input-output norms require importers to match declared chemical inputs to the proportions needed for export production.

Standard input-output norms prescribe the proportions of chemical inputs required per unit of specified export products and list constituent inputs with their measurement units. The schedules establish a determination mechanism for the proportion of various inputs usable or required in manufacture and impose an obligation on applicants to ensure that imported goods correspond to the inputs actually used or required in the declared export product.
