A word of counsel

The most common error on this tariff line is filing the bill of entry with standard commodity descriptions and omitting the Chapter 28 additional qualifiers required since 15 October 2023. An incomplete qualifier declaration is treated as a deficient import document under the Customs Act, 1962, exposing the consignment to detention and demurrage while corrections are processed; the qualifier fields must be populated at the time of initial filing, not as a post-assessment amendment.

Frequently asked
Does HSN 2833 27 00 require BIS certification?
No, barium sulphate is not covered by any BIS Quality Control Order. The operative compliance requirement is the CBIC mandatory additional qualifier regime for Chapter 28 commodities under CBIC Circular 23/2023-Cus dated 30-09-2023.
Which specific qualifier fields must be completed under CBIC Circular 23/2023-Cus for Chapter 28 imports?
The qualifiers are specified in Paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus; importers should consult those paragraphs directly and ensure each mandatory field in the import declaration is populated before filing.
Does the mandatory qualifier requirement apply to all Chapter 28 commodities or only to selected tariff lines?
The requirement applies broadly to commodities under Chapters 28, 29, 32, 39 and CTH 3808 as specified in the Circular; barium sulphate under Chapter 28 falls squarely within this scope.
