A word of counsel

The most common error on this tariff line is filing the bill of entry under the parent Chapter 32 format without populating the specific qualifiers mandated by CBIC Circular 23/2023-Cus — a deficiency that is not self-correcting and requires a fresh presentation or amendment, generating demurrage and ground rent during the rectification window. The qualifier regime applies equally to synthetic organic colouring matter imported as a pure substance and as a mixture under sub-heading 3204 19, so blended azoic intermediate imports do not escape the obligation.
