Compliance steps

1
Include all mandatory additional qualifiers in the import declaration for this Chapter 28 commodity as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus. Non-compliant declarations filed on or after 15 October 2023 are liable to customs detention at the bill-of-entry stage.

Verify that the customs broker has correctly mapped the Chapter 28 qualifier fields in the ICEGATE bill-of-entry format before submission. Omission or incorrect population of qualifier fields triggers a query from the assessing officer and delays out-of-charge.

A word of counsel

The most common error on this tariff line is filing the bill of entry with a generic Chapter 28 description and no additional qualifiers, treating the CBIC circular as a downstream formality rather than a pre-filing obligation. Qualifier fields for Chapters 28, 29, 32, 39 and CTH 3808 are verified at the time of assessment; a missing qualifier does not attract a rectifiable-labelling remedy — it requires a fresh amendment to the bill of entry, causing demurrage and ground rent on perishable or time-sensitive chemical consignments.

Frequently asked

Does HSN 2841 80 90 require BIS certification?

Paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus specify the qualifier fields to be populated in import declarations for Chapter 28 commodities; the exact field list is set out in the Circular's annexure and must be confirmed against the current ICEGATE bill-of-entry format.

Does the qualifier obligation under CBIC Circular 23/2023-Cus apply to all importers or only to specific categories?

The obligation applies to all importers filing bills of entry for commodities under Chapters 28, 29, 32, 39 and CTH 3808 without exception; no carve-out for EOU, SEZ, or advance authorisation holders is provided in the Circular.
