Standard input-output norms govern permissible inputs for export manufacture and require imported goods to match export use.

Standard input-output norms prescribe permissible raw inputs and their proportions for guaifenesin manufacture, listing guaiacol and either epichlorohydrin or alpha glyceryl monochlorohydrin with corresponding input measures. Applicants must ensure imported goods are those actually used or required in the declared export product, and proportions of inputs applicable to each resultant product must be determined to verify export-use consistency.
