CIB&RC CLEARANCE · NDPS CLEARANCE

HSN 2933 39 29 (other nitrogen heterocyclic compounds) is subject to dual primary regulation: the Central Insecticides Board and Registration Committee (CIB&RC) governs items falling under the Schedule to the Insecticides Act, 1968, requiring registration and an import permit, while the Narcotic Drugs and Psychotropic Substances (NDPS) framework mandates a consignment-wise NOC from the Narcotics Commissioner for controlled substances ANPP and NPP. The Directorate General of Foreign Trade (DGFT) and Central Board of Indirect Taxes and Customs (CBIC) apply policy and declaration overlays, including mandatory Chapter 29 additional qualifiers effective 15 October 2023.

Compliance steps

1
If the consignment contains a substance listed in the Schedule to the Insecticides Act, 1968, obtain a registration certificate and import permit from the Secretariat of CIB&RC before shipment. Import is restricted to ports specified under Rule 45 of the Insecticides Rules, 1971; diversion to an unnotified port constitutes a violation of the Act.

2
For consignments containing 4-anilino-N-phenethylpiperidine (ANPP) or N-phenethyl-4-piperidone (NPP), obtain a consignment-wise NOC from the Narcotics Commissioner under the NDPS (Regulation of Controlled Substances) Order, 2013. Upload mandatory documents — certificate of analysis (0010dc), batch release certificate (0030dc), label of consignment (0110dc), registration certificate for drugs (101dc1), and import licence for drugs (9111dc) — in e-Sanchit before out-of-charge.

Ensure the bill of entry includes the mandatory additional qualifiers for Chapter 29 commodities as stipulated in Para 4.1 and 4.2 of CBIC Circular 23/2023-Cus dated 30-09-2023, effective 15 October 2023. Consignments under Chapters 28, 29, 32, 39 and CTH 3808 that omit these qualifiers are liable to detention pending amendment of the import declaration.

A word of counsel

The most common error on this tariff line is importing without confirming whether the specific compound falls within both the CIB&RC schedule and the NDPS controlled-substances list — importers often address one regime and overlook the other. ANPP and NPP require a fresh consignment-wise NOC for every shipment; a previously valid NOC does not carry over to a new consignment. Additionally, the PLI Act, 1991 insurance obligation under S.O. 227(E) dated 24-03-1992 applies where import quantities of specified hazardous substances exceed the thresholds set by the Ministry of Environment and Forests.

Frequently asked

Does HSN 2933 39 29 require BIS certification?

No, no BIS Quality Control Order covers this product family. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968 for scheduled pesticide substances, and by the NDPS (Regulation of Controlled Substances) Order, 2013 for controlled precursor chemicals ANPP and NPP.

Are all compounds under HSN 2933 39 29 subject to CIB&RC registration and the NDPS NOC requirement?

No. CIB&RC registration and the port restriction under Rule 45 of the Insecticides Rules, 1971 apply only to substances listed in the Schedule to the Insecticides Act, 1968; the NDPS NOC applies specifically to ANPP and N-phenethyl-4-piperidone (NPP) per DGFT Notification 15/2015-20.

What happens if the mandatory Chapter 29 qualifiers are omitted from the import declaration?

The consignment is liable to detention pending amendment of the bill of entry; CBIC Circular 23/2023-Cus dated 30-09-2023 made these additional qualifiers mandatory for all Chapter 29 import declarations with effect from 15 October 2023.
