A word of counsel

The most common error on this tariff line is importing magnesium thiosulphate without assessing whether the specific consignment qualifies as a drug under the Drugs and Cosmetics Act, 1940 — a determination that triggers a five-document e-Sanchit bundle entirely distinct from the Chapter 28 qualifier obligation. Importers who treat the CBIC Circular 23/2023-Cus qualifier as the sole compliance requirement, overlooking the drug-classification overlay, face consignment detention pending retroactive document upload and potential out-of-charge refusal.
