A word of counsel

The most common error on this tariff line is treating sodium hydrosulphite purely as an industrial inorganic chemical and overlooking the drug-documentation overlay triggered when the product is classified or used as a pharmaceutical-grade substance. If the consignment carries a drug-grade specification, all five e-Sanchit documents — including the import licence for drugs (9111dc) and the registration certificate (101dc1) — must be uploaded before out-of-charge; absence of even one triggers detention and demurrage while the proper officer awaits PGA resolution.
