A word of counsel

The 30-day post-import notification window is a hard statutory obligation — not a customs clearance condition — and is frequently overlooked because the bill of entry issues normally without it. Failure to notify the National Authority CWC, the Department of Chemicals and Petrochemicals, and DGFT, or to submit the bill of entry copy to DGFT within 30 days of import, constitutes a standalone breach of the CWC Category 1B import conditions and attracts DGFT enforcement independent of customs out-of-charge status.

Frequently asked

Does HSN 2930 90 96 require BIS certification?

Is the post-import notification to DGFT and the National Authority CWC required for every consignment?

Yes, the notification obligation applies to each import consignment individually: details must be notified to the National Authority CWC (D&ISA), the Department of Chemicals and Petrochemicals, and DGFT, and a copy of the bill of entry submitted to DGFT, all within 30 days of import.
