2
File the bill of entry with the correct 8-digit CTH 3204 12 23 and attach the compliant declaration in e-Sanchit before seeking out-of-charge. Non-compliance with the qualifier requirement at the bill-of-entry stage may result in detention of the consignment pending rectification.

A word of counsel

The most common error on this tariff line is filing the bill of entry without the Chapter 32 mandatory qualifiers prescribed under paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus — a deficiency that is not rectifiable after out-of-charge is granted and can result in consignment detention and demurrage. Because this is a declaration-completeness obligation rather than a licence or permit, importers sometimes treat it as administrative boilerplate; customs officers treat a missing qualifier as a substantive non-compliance.

Frequently asked

Does HSN 3204 12 23 require BIS certification?

No, acid dyes including Acid green 28 are not covered by any BIS Quality Control Order. Import is governed by the Central Board of Indirect Taxes and Customs mandatory-qualifier requirement under CBIC Circular 23/2023-Cus, with the ITC (HS) import policy otherwise treating this tariff line as free.

What qualifiers must be included in the import declaration under CBIC Circular 23/2023-Cus?

Paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus specify the mandatory additional qualifiers for Chapters 28, 29, 32, 39 and CTH 3808; the circular should be consulted for the exact field-by-field specification, as the requirement has been operative since 15 October 2023.

Does the Chapter 32 qualifier obligation apply if the consignment is imported under an advance authorisation or by an EOU?

Yes. CBIC Circular 23/2023-Cus applies at the bill-of-entry stage regardless of the import scheme; the qualifier obligation is a declaration-accuracy requirement and is not waived by advance authorisation or EOU status.
