A word of counsel

The most common error on this tariff line is filing the bill of entry without the Chapter 32 additional qualifiers mandated under paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus — particularly where the importer treats azoic dye intermediates as generic chemicals and overlooks the chapter-specific declaration requirement. A declaration deficient in the prescribed qualifiers is liable to detention pending amendment, with demurrage and ground rent accruing until the corrected entry is re-assessed and out-of-charge granted.
