Standard input output norms require imported chemical inputs to match those used in the export product, with SION suspended. Standard input-output norms for entry A1409 (Monocyclohexyl amine) specify input proportions - including Cyclohexanol and Nickel Catalyst - to determine permissible use in producing export products. The SION for this entry is suspended, and applicants must ensure imported goods are those used or required in the export product.
