Compliance steps

1
Obtain a consignment-wise NOC from the Narcotics Commissioner for the controlled substance N-Phenethyl-4-piperidone (NPP) / 4-anilino-N-phenethylpiperidine (ANPP) before filing the bill of entry. Each consignment requires a fresh NOC; a single standing authorisation does not suffice.

2
Where the substance falls within the Schedule to the Insecticides Act, 1968, obtain registration and an import permit from the Central Insecticides Board and Registration Committee. Import is restricted to places notified under Rule 45 of the Insecticides Rules, 1971; verify the permitted port of import before shipment.

Ensure mandatory additional qualifiers are declared in the import declaration for commodities under Chapter 29 as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus, with effect from 15-10-2023. Where the quantity of specified hazardous substances exceeds the prescribed threshold, obtain insurance under the Public Liability Insurance Act, 1991 per S.O. 227(E) dated 24-03-1992.

A word of counsel

The most common error on this tariff line is conflating the NDPS controlled-substance NOC with the CIB&RC insecticide-import permit and treating satisfaction of one as covering both. The two regimes are independent: the NDPS NOC is consignment-specific and issued by the Narcotics Commissioner, while the CIB&RC registration and permit apply only where the substance appears in the Insecticide Act Schedule — and the port of import for the CIB&RC stream is separately restricted under Rule 45 of the Insecticides Rules, 1971. Filing a bill of entry without the consignment-wise NDPS NOC uploaded exposes the shipment to seizure and criminal liability under the NDPS Act.

Frequently asked

Does HSN 2933 37 00 require BIS certification?

No, no BIS Quality Control Order covers NPP or heterocyclic nitrogen compounds under this tariff line. Import is governed by the NDPS (Regulation of Controlled Substances) Order, 2013 requiring a consignment-wise NOC from the Narcotics Commissioner, with a concurrent CIB&RC permit where the substance is scheduled under the Insecticides Act, 1968.

Is the NDPS NOC required for every shipment, or is a single annual authorisation sufficient?

The NOC is consignment-wise, meaning a separate authorisation from the Narcotics Commissioner is required for each individual consignment of NPP or ANPP, per DGFT Notification 15/2015-20 dated 21-07-2015.

When does the Public Liability Insurance requirement under S.O. 227(E) apply to this import?

The insurance obligation under the Public Liability Insurance Act, 1991 is triggered when the import quantity of specified hazardous substances exceeds the threshold prescribed in S.O. 227(E) dated 24-03-1992; the owner must take out the policy before the consignment is cleared.
