Input-output norms require matching imported chemical inputs to those actually used in the exported dye under FTP suspension notice.

Standard input-output norms for Reactive Yellow M4G C.I. Reactive Yellow-22 prescribe constituent inputs (cyanuric chloride; meta phenylene diamine sulphonic acid; 1,4 sulphophenyl-3-carboxy-5-pyrazolone) and note the entry's suspension. Determination of permissible input proportions is required for manufacture of resultant products, and applicants must ensure imported goods correspond to the inputs actually used or required in the export product.
