Input-output norms for chemical exports require imported inputs to match actual manufacturing use for export products.

Standard Input-Output Norms for Ammonium Bifluoride note the SION suspension and specify constituent inputs including Acid Grade Fluorspar and Hydrofluoric Acid 70%. Authorities determine proportions of inputs usable or required for resultant products, and applicants must ensure imported goods are those used or required in the export product, creating a compliance obligation to match imports to actual manufacturing use.
