Input composition requirements mandate declared input proportions and that imported materials match intended valve export use.

Input composition requirements prescribe permissible input materials for inlet/exhaust valves and set weight based input norms per unit or per kilogram of export product to determine allowable usage. Applicants must ensure imported goods correspond to the inputs used or required in the export product, and the schedule requires determination of proportions of various inputs applied to different resultant products for compliance verification.
