1
Ensure the import declaration for this consignment includes all mandatory additional qualifiers prescribed under Paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus. These qualifiers are compulsory for all commodities under Chapter 32, effective 15 October 2023, and an incomplete declaration will result in detention at the bill-of-entry stage.

2
Verify that the specific chemical identity of the dye — Acid Blue 2 (C.I. Acid Blue 2, alizarine brill blue PFN) — is accurately declared in the import documentation, consistent with the Chapter 32 qualifier requirements. Mis-description of the dye category or trade name is a separate customs mis-declaration exposure under the Customs Act, 1962.

A word of counsel

The most common error on this tariff line is filing the bill of entry without the mandatory Chapter 32 qualifiers required under CBIC Circular 23/2023-Cus, treating the declaration as a routine chemical import. Omission of the stipulated qualifiers in Paragraphs 4.1 and 4.2 renders the declaration deficient, exposing the consignment to detention and demurrage while the importer files a corrected entry; the circular applies equally to Chapter 28, 29, 39 and CTH 3808 goods, so multi-chapter shipments must be reviewed line by line.

Frequently asked

Does HSN 3204 12 41 require BIS certification?

No, acid dyes and mordant dye preparations under this tariff line are not covered by any BIS Quality Control Order. The operative requirement is the mandatory declaration of additional qualifiers under CBIC Circular 23/2023-Cus dated 30-09-2023, applicable to all Chapter 32 commodities with effect from 15 October 2023.

Which specific qualifiers must be declared at the bill of entry for this HSN?

The qualifiers are those stipulated in Paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus dated 30-09-2023; the importer should refer to the Circular Annexure covering Chapter 32 commodities to identify the exact fields required.

Does the CBIC Circular 23/2023-Cus qualifier requirement apply if the dye is imported as part of a preparation rather than in pure form?

Yes. The Circular applies to commodities classifiable under Chapter 32, which includes preparations based on acid dyes; the qualifier obligation attaches to the tariff classification, not to whether the product is pure or a preparation.
