Input-output compliance: imported dye inputs must match prescribed component proportions and be used in the export product.

Standard input-output norms specify constituent inputs and per-unit weights for Acid Red 18 (Food Red 7), Ponceau 4R (dye content eighty percent), listing Sodium Naphthionate, Sodium Nitrite, Beta Naphthol, Caustic Soda and Soda Ash. The schedule requires determination of permissible input proportions for manufacture and imposes on applicants the obligation that imported goods are those used or required in the export product and conform to prescribed proportions.
