A word of counsel

The most common error on this tariff line is filing the bill of entry without the Chapter 32 mandatory qualifiers, treating this synthetic organic dye intermediate as a routine chemical import. CBIC Circular 23/2023-Cus applies to all commodities under Chapters 28, 29, 32, 39 and CTH 3808; the absence of the prescribed qualifiers at the time of filing triggers examination and detention, not merely a post-filing amendment.

Frequently asked

Does HSN 3204 19 25 require BIS certification?

No, no BIS Quality Control Order covers azoic coupling components or synthetic organic dye intermediates under this tariff line. Import is governed by the CBIC mandatory-qualifier regime under CBIC Circular 23/2023-Cus dated 30-09-2023 for Chapter 32 commodities.

From which date are the Chapter 32 mandatory qualifiers compulsory, and what exactly must be declared?

The mandatory qualifiers became compulsory with effect from 15 October 2023; the specific chemical-identity and composition details required are prescribed in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus dated 30-09-2023.

Does the CBIC mandatory-qualifier requirement apply only to this specific HSN or to the broader Chapter?

It applies to all commodities under Chapters 28, 29, 32 and 39 and CTH 3808, so the obligation covers the full Chapter 32 product range, including all synthetic organic colouring matter subheadings, not only HSN 3204 19 25.
