A word of counsel

The most common error on this tariff line is treating the Narcotics Commissioner NOC and the CIB&RC permit as alternatives rather than potentially concurrent requirements. Where trimeperidine figures in the Schedule to the Insecticides Act, 1968, both clearances are required before out-of-charge, and arrival at a port that is not a restricted place notified under Rule 45 of the Insecticides Rules, 1971, will ground the consignment regardless of the validity of either clearance.

Frequently asked

Does HSN 2933 33 35 require BIS certification?

No. No BIS Quality Control Order covers trimeperidine or its salts under Chapter 29. Import is governed by the Narcotics Commissioner NOC requirement and, where the substance is scheduled under the Insecticides Act, 1968, by CIB&RC registration and permit, with ITC (HS) Chapter 29 policy condition 3 administered by DGFT.

At which ports may trimeperidine be imported, and is the CIB&RC permit port-specific?

Import of insecticide-scheduled substances is restricted to places notified under Rule 45 of the Insecticides Rules, 1971; routing a consignment to an unnotified port renders it liable to detention regardless of permit validity.

Does the 30-day post-import CWC notification obligation apply even when importing from a non-State Party?

Yes. Chapter 29 policy condition 3, as notified by DGFT Notification 54/2015-20 dated 09-02-2022, requires notification to the National Authority, Chemical Weapons Convention, and submission of the bill of entry to DGFT within 30 days for every consignment, irrespective of the exporting country's CWC status.
