Ensure the import declaration for HSN 2850 00 41 includes all mandatory additional qualifiers for Chapter 28 commodities as stipulated in Paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus. This requirement has been operative with effect from 15 October 2023 and applies at every bill-of-entry filing.

2
Verify that the qualifier fields are correctly populated in the e-filing system before submitting the bill of entry; incomplete or absent qualifiers will cause the declaration to be flagged by the system, resulting in detention and demurrage pending correction.

A word of counsel

The most common error on this tariff line is filing the bill of entry without the Chapter 28 mandatory qualifiers, treating this residual 8-digit line as a generic inorganic chemical that escapes the Circular 23/2023-Cus overlay. The qualifier obligation applies to all commodities under Chapter 28 without exception, and a declaration submitted without the Paragraph 4.1 and 4.2 fields populated is treated as a deficient declaration — attracting detention, demurrage, and potential penalty under the Customs Act, 1962.
