Input-output norms require imported chemical inputs to match declared use in export manufacture, with the SION entry suspended. The SION for Reactive Blue 221 requires specified input quantities per kilogram of finished product-Cyanuric Chloride (0.187 kg) and N Ethyl Meta Base Ester (0.310 kg)-and obliges applicants to ensure imported inputs are those used in the export product; the entry is noted as suspended by Public Notice.
