Vat blue 1 (synthetic indigo)
Vat blue 1 synthetic indigo dye, vat dye preparations
HSN 3204 15 51 (Vat blue 1, synthetic indigo) is governed by Central Board of Indirect Taxes and Customs (CBIC) Circular 23/2023-Cus dated 30-09-2023, which mandates additional chemical qualifiers in the import declaration for all commodities under Chapter 32 with effect from 15 October 2023. No sectoral PGA licence or permit applies; the operative obligation is accurate declaration of the qualifying parameters at the bill-of-entry stage.
- Chapter 32 qualifiers declaration from CBIC
- Technical data sheet from exporter
- 1Ensure the import declaration for this consignment includes all mandatory additional qualifiers for Chapter 32 commodities as prescribed in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus. This obligation applies with effect from 15 October 2023 and non-compliance exposes the bill of entry to misdeclaration proceedings.CBIC Circular 23/2023-Cus dated 30-09-2023, para 4.1 and 4.2
- 2Obtain a technical data sheet or Certificate of Analysis from the foreign supplier confirming the chemical identity and purity of Vat blue 1 (synthetic indigo), as this supports accurate completion of the Chapter 32 qualifiers and provides documentary evidence against any customs query on composition.CBIC Circular 23/2023-Cus dated 30-09-2023, para 4.1 and 4.2
The most common error on this tariff line is filing the bill of entry without the Chapter 32 mandatory qualifiers, treating synthetic indigo as a commodity for which a bare product description suffices. CBIC Circular 23/2023-Cus extends the qualifier requirement across all eight-digit CTIs within Chapters 28, 29, 32, 39 and CTH 3808; an incomplete declaration triggers detention and a misdeclaration notice even where the goods themselves are correctly classified.
