Compliance steps
  1. 1
    At the time of filing the bill of entry, include all mandatory additional qualifiers for Chapter 32 commodities as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus. These qualifiers have been mandatory with effect from 15 October 2023 and their absence renders the import declaration non-compliant.

  2. 2
    Verify that the import declaration accurately describes the colouring matter as natural indigo (vegetable origin) and not a synthetic or chemically-defined substitute, as the qualifier regime under Chapter 32 is commodity-specific and an incorrect description may attract misdeclaration proceedings 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 Chapter 32 mandatory qualifiers introduced by CBIC Circular 23/2023-Cus, treating them as administrative formalities rather than compliance conditions. An import declaration lodged without the stipulated qualifiers is flagged for examination and can result in consignment detention and demurrage pending rectification; re-submission after goods arrival does not cure the initial non-compliance.

Frequently asked
Does HSN 3203 00 40 require BIS certification?
No, natural indigo is not within the BIS Quality Control Order regime. Import compliance for this tariff line is governed by the Central Board of Indirect Taxes and Customs under CBIC Circular 23/2023-Cus, which mandates additional qualifiers in import declarations for Chapter 32 commodities.
From which date are the Chapter 32 mandatory qualifiers operative, and which paragraphs of the Circular apply?
The mandatory additional qualifiers apply with effect from 15 October 2023 under paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus dated 30 September 2023; the same Circular also covers Chapters 28, 29, 39, and CTH 3808.
Does the Chapter 32 qualifier requirement apply only to natural indigo or to all colouring matter under HSN 3203?
The qualifier requirement applies at the Chapter 32 level and therefore covers all commodities under Chapter 32, including all sub-headings of HSN 3203; natural indigo under 3203 00 40 is not a carve-out and must comply in full.
