A word of counsel

The most common error on this tariff line is filing the bill of entry with generic Chapter 32 colouring-matter descriptors and omitting the chemical-identity qualifiers now mandatory under CBIC Circular 23/2023-Cus. The qualifier requirement applies across Chapters 28, 29, 32, 39 and CTH 3808; importers who treat the qualifier fields as optional risk examination, detention, and demurrage while the entry is returned for amendment.
