A word of counsel

The most common error on this tariff line is filing a standard bill of entry without appending the Chapter 28 mandatory qualifiers, treating nickel sulphate as a routine industrial chemical entry. CBIC Circular 23/2023-Cus applies to all commodities under Chapter 28, and the qualifier fields in the import declaration must be populated before the bill of entry is assessed; a deficient declaration is not curable after the out-of-charge gate, and the consignment faces detention and demurrage pending rectification.

From which date are the Chapter 28 mandatory qualifiers operative for this HSN?
The qualifier requirements for Chapter 28 commodities, including nickel sulphate, became mandatory with effect from 15 October 2023 per CBIC Circular 23/2023-Cus dated 30-09-2023.
Do the CBIC qualifier requirements under Circular 23/2023-Cus apply only to Chapter 28, or to other chapters as well?
Circular 23/2023-Cus extends mandatory additional qualifiers to commodities under Chapters 28, 29, 32, 39 and CTH 3808; nickel sulphate under Chapter 28 falls squarely within this scope.
