Compliance steps

1
Include the mandatory additional qualifiers specified in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus in the import declaration for every consignment of Disperse blue 1 filed on or after 15 October 2023. Declarations submitted without these qualifiers are liable to rejection at the bill-of-entry stage.

2
Verify that the qualifier data accurately reflects the consignment — chemical identity, purity, and preparation basis — as declarations for Chapter 32 synthetic organic colouring matter are subject to post-clearance audit. Inaccurate or incomplete qualifiers attract a customs penalty under the Customs Act, 1962.

A word of counsel

The most common error on this tariff line is filing the bill of entry using a legacy declaration template that pre-dates 15 October 2023, which omits the Chapter 32 mandatory qualifiers entirely. Because Disperse blue 1 is a named 8-digit CTI within the broader Chapters 28, 29, 32, 39 and CTH 3808 qualifier mandate, even a single missing qualifier field triggers a misdeclaration finding — not merely a rectifiable defect — and can result in consignment detention pending a corrected entry.

Frequently asked

Does HSN 3204 11 51 require BIS certification?

No; no BIS Quality Control Order covers disperse dyes or synthetic organic colouring matter under this tariff line. The operative requirement is the mandatory additional qualifier declaration administered by the Central Board of Indirect Taxes and Customs under CBIC Circular 23/2023-Cus dated 30-09-2023.

From which date are the Chapter 32 mandatory qualifiers operative for this HSN?

The qualifier requirement under paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus applies with effect from 15 October 2023 for all import declarations covering commodities under Chapters 28, 29, 32, 39 and CTH 3808, including HSN 3204 11 51.

Are all disperse dye preparations under heading 3204 11 subject to the same qualifier requirement?

Yes; the CBIC Circular 23/2023-Cus qualifier mandate applies at the chapter level — all CTIs under Chapter 32 are captured, meaning the entire disperse dyes subheading 3204 11 is within scope, not just the Disperse blue 1 tariff line.
