- Chapter 32 qualifiers from CBIC
- Import declaration from CBIC
- 1Include all mandatory additional qualifiers for Chapter 32 commodities in the import declaration as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus. These qualifiers are compulsory at the bill-of-entry stage with effect from 15 October 2023; an incomplete declaration will cause the bill to be held at assessment.CBIC Circular 23/2023-Cus dated 30-09-2023, para 4.1 and 4.2
- 2Verify that the declared qualifiers accurately describe the specific dye identity — Acid Blue 51 (Colour Index name: Alizarine Sky Blue FFB) — to satisfy the chemical-identity specificity requirements expected under the Chapter 32 qualifier regime. Misdescription may trigger re-assessment or detention.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 the requirement as optional for chemically well-known dyes. CBIC Circular 23/2023-Cus applies uniformly across all commodities under Chapters 28, 29, 32, 39 and CTH 3808 regardless of the importer's prior familiarity with the product — an absent or incomplete qualifier declaration results in bill-of-entry detention and reassessment delay, with attendant demurrage and ground rent at the port.
