Standard Input-Output Norms suspended; importers must match and verify inputs used in exported chemical products.

Standard Input-Output Norms for Tetra methyl thiouram disulphide (M.P. above 142 C) have been suspended by public notice while listing prescribed inputs and quantities. The framework requires determination of permissible proportions of inputs used in manufacture and obliges applicants to ensure imported goods correspond to those used or required in the export product, with verification that imports conform to declared input-output usage.
