A word of counsel

The most common error on this tariff line is filing the import declaration without the Chapter 28 additional qualifiers mandated from 15 October 2023, treating potassium nitrate as a straightforward industrial chemical. Where the consignment bears a drug classification, the full set of five e-Sanchit document codes is independently required; omitting even one — most often the batch release certificate (0030dc) — triggers detention at the port of import pending rectification.
