Standard Input-Output norms require imported inputs to match those used in the export product, with SION suspended.

Standard Input-Output norms for Vat Yellow GCN U/D (Vat Yellow 2) list constituent inputs and their weights per unit of product, and record the SION entry A1017 as suspended by Public Notice No. 03/2024-25. Regulatory determination fixes allowable input proportions for manufacture, and applicants must ensure imported goods are those used or required in the export product.
