A word of counsel

The most common oversight on this residual CTI is failing to identify whether the specific compound falls within the CWC Schedule 1 (Category 1B) phosphorus-group definition. Importers who treat the Free-import status of HSN 2931 59 90 as an unconditional clearance and skip the 30-day post-import notification to the National Authority CWC and DGFT expose themselves to separate enforcement action under the Chemical Weapons Convention Act independent of customs clearance. The CBIC Chapter 29 qualifiers obligation under Circular 23/2023-Cus applies to every consignment under this CTI regardless of the CWC status of the substance.

Frequently asked

Does HSN 2931 59 90 require BIS certification?

No, no BIS Quality Control Order covers this residual organo-inorganic compounds tariff line. Import is governed by the Directorate General of Foreign Trade under the ITC (HS) policy, with a Free-import status per DGFT Notification 44/2025-26 and CBIC mandatory Chapter 29 declaration qualifiers under Circular 23/2023-Cus.

What is the 30-day notification obligation for CWC Schedule 1 Category 1B compounds?

Within 30 days of import, the importer must notify consignment details to the National Authority CWC (Cabinet Secretariat, Ministry of External Affairs, D&ISA), the Department of Chemicals and Petrochemicals, and DGFT, and submit a copy of the bill of entry to DGFT — applicable only to compounds falling within the CWC Schedule 1 phosphorus-group definition.

Does the Free-import status under DGFT Notification 44/2025-26 eliminate all conditions on this CTI?

No. Free-import status removes the licence requirement but CWC Schedule 1 Category 1B sourcing and notification conditions, the Public Liability Insurance obligation for specified hazardous quantities, and CBIC Chapter 29 mandatory qualifiers under Circular 23/2023-Cus all remain operative independently.
