A word of counsel

The most common error on this tariff line is filing an import declaration with a generic dye or colourant description and omitting the Chapter 32 additional qualifiers mandated from 15 October 2023. A declaration missing the paragraph 4.1 and 4.2 qualifiers will be flagged at the bill-of-entry stage, resulting in detention and ground rent accumulation until the declaration is corrected or a fresh bill of entry is filed.
