  3. 3
    Ensure the import declaration 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 applies with effect from 15 October 2023 and non-compliance triggers declaration rejection at the bill of entry stage.

A word of counsel

The most common error on this tariff line is treating clearance of the consignment as the end of the compliance obligation. The post-import notification to the National Authority, Cabinet Secretariat, Ministry of External Affairs (D & ISA), Department of Chemicals and Petrochemicals, and DGFT — together with submission of the bill of entry copy to DGFT — must be completed within 30 days of each import; a missed deadline on any one of these five recipients constitutes a separate CWC policy breach, with potential prosecution consequences under the Chemical Weapons Convention Act.
