A word of counsel

The most common error on this tariff line is filing the bill of entry with generic colouring-matter particulars and omitting the chemical-identity qualifiers now mandatory under CBIC Circular 23/2023-Cus. Because Chapters 28, 29, 32, 39 and CTH 3808 are listed together in the circular, importers who have updated their declarations for bulk chemicals under Chapter 29 sometimes assume the same qualifier set covers Chapter 32 dyes — the specific qualifier fields for Chapter 32 are distinct and must be populated separately for each consignment.

Frequently asked

Does HSN 3204 12 22 require BIS certification?

No, synthetic acid dyes under this tariff line are not covered by any BIS Quality Control Order. The operative requirement is the mandatory declaration qualifier obligation under CBIC Circular 23/2023-Cus dated 30-09-2023, which applies to all Chapter 32 import declarations with effect from 15 October 2023.

From which date are the Chapter 32 declaration qualifiers mandatory, and which circular governs them?

The mandatory additional qualifiers for Chapter 32 commodities are effective from 15 October 2023 under CBIC Circular 23/2023-Cus dated 30-09-2023, paragraphs 4.1 and 4.2.

Does the qualifier requirement apply only to Chapter 32, or are other chapters also covered?

The same circular covers Chapters 28, 29, 32 and 39 as well as CTH 3808; however, the specific qualifier fields differ by chapter, and Chapter 32 dye declarations must populate the qualifier set designated for that chapter.
