Input composition control for PVC organotin stabilizers requires imported inputs to match declared manufacturing proportions for export.

Input-output norms for PVC organotin stabilizers set the operative input composition standard, listing constituent inputs and proportions (tetra butyl tin, EHIG, tin tetra chloride, DBTO) and require that imported goods correspond to the inputs and proportions needed for the export product; the entry is noted as suspended by public notice.
