CIB&RC CLEARANCE · NDPS CLEARANCE

HSN 2912 29 90 (other cyclic aldehydes) is subject to dual primary regulation: items falling within the Schedule to the Insecticides Act, 1968 require registration and an import permit from the Central Insecticides Board and Registration Committee (CIB&RC) under Rule 45 of the Insecticides Rules, 1971, while substances meeting the Narcotic Drugs and Psychotropic Substances (NDPS) definition are governed by Chapter VII-A of the NDPS Rules, 1985. Directorate General of Foreign Trade (DGFT) and Central Board of Indirect Taxes and Customs (CBIC) policy overlays — including mandatory Chapter 29 additional qualifiers under CBIC Circular 23/2023-Cus — apply at the bill of entry.

Compliance steps
  1. 1
    Verify whether the specific aldehyde compound falls within the Schedule to the Insecticides Act, 1968. If so, obtain registration and an import permit from the secretariat of the Central Insecticides Board and Registration Committee before shipment, and route the consignment only through ports notified under Rule 45 of the Insecticides Rules, 1971.
    Insecticides Act, 1968 · Rule 45 of the Insecticides Rules, 1971 · ITC (HS) policy condition 2 of Chapter 29
  2. 2
    If the compound falls within the NDPS framework, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 before filing the bill of entry. Imports for medical and scientific purposes proceed under Chapter VII-A of the NDPS Rules, 1985; all other NDPS imports are governed by Appendix-I to the ITC (HS) Schedule.

  3. 3
    Comply with CBIC Circular 23/2023-Cus dated 30-09-2023 by including mandatory additional qualifiers in the import declaration for Chapter 29 commodities as stipulated in Paragraphs 4.1 and 4.2, with effect from 15 October 2023. Where the imported quantity of specified hazardous substances exceeds notified thresholds, take out an insurance policy under the Public Liability Insurance Act, 1991 per S.O. 227(E) dated 24-03-1992.

A word of counsel

The critical error on this tariff line is assuming the compound is out of scope for both CIB&RC and NDPS without conducting a Schedule or Appendix-I check against the specific chemical identity. A compound that appears in neither the pesticide Schedule nor the NDPS Appendix clears under the standard DGFT and CBIC Chapter 29 qualifier regime — but one that is scheduled triggers a port-restricted, permit-gated entry path, and importing through an unnotified port or without the CIB&RC permit constitutes a violation of the Insecticides Act, 1968 regardless of CBIC clearance.

Frequently asked
Does HSN 2912 29 90 require BIS certification?
No; no BIS Quality Control Order covers cyclic aldehyde compounds under this residual tariff line. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968 where the substance is scheduled, and by the NDPS Rules, 1985 where the substance meets the narcotic or psychotropic definition.
Are all ports open for import of insecticides under this tariff line?
No. Places at which insecticides may be imported are restricted under Rule 45 of the Insecticides Rules, 1971; importers must confirm the notified port list with the CIB&RC secretariat before placing the purchase order.
What happens if the imported aldehyde compound is a hazardous substance imported in quantities above the notified threshold?
The owner must take out a Public Liability Insurance policy as per the Public Liability Insurance Act, 1991, as detailed in S.O. 227(E) dated 24-03-1992 issued by the Ministry of Environment and Forests; failure to do so constitutes a separate statutory non-compliance independent of customs clearance.
