Isocyanates and other nitrogen-function compounds (residual)
HSN 2929 10 90 (Other isocyanates) is subject to Central Insecticides Board and Registration Committee (CIB&RC) registration and import permit under the Insecticides Act, 1968 where the substance figures in the Schedule to that Act. Items that qualify as narcotic drugs or psychotropic substances are additionally governed by the Narcotic Drugs and Psychotropic Substances (NDPS) import-certificate regime under Chapter VII-A of the NDPS Rules, 1985, and the Directorate General of Foreign Trade (DGFT) ITC (HS) policy condition 2 of Chapter 29 applies as the overarching trade-policy overlay.
- Registration certificate from CIB&RC
- Import permit from CIB&RC
- Chapter 29 qualifiers from CBIC
Procedural directions for customs clearance are issued by: Directorate General of Foreign Trade, Central Board of Indirect Taxes and Customs.
- 1Determine whether the specific isocyanate compound falls within the Schedule to the Insecticides Act, 1968. If so, obtain both the registration certificate and an import permit from the Secretariat of the Central Insecticides Board and Registration Committee, 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
- 2Where the substance is also listed as an NDPS substance, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 before shipment. Imports for medical and scientific purposes proceed under the special provisions of Chapter VII-A of the NDPS Rules, 1985; all other imports are governed by Appendix-I to the ITC (HS) Schedule per DGFT ITC (HS) policy condition 2 of Chapter 29.Rule 53 of the NDPS Rules, 1985 · ITC (HS) policy condition 2, Chapter 29
- 3Comply with CBIC Circular 23/2023-Cus dated 30-09-2023, which mandates additional qualifiers in import declarations for Chapter 29 commodities with effect from 15-10-2023. Separately, where the import of specified hazardous substances exceeds the specified quantities, the owner must obtain a public liability insurance policy under the provisions of S.O. 227(E) dated 24-03-1992.CBIC Circular 23/2023-Cus dated 30-09-2023 · S.O. 227(E) dated 24-03-1992
The most common error on this tariff line is importing on the assumption that CIB&RC compliance alone exhausts the regulatory burden, without checking whether the specific compound also appears on the NDPS schedule. A substance can simultaneously fall within the Insecticides Act Schedule and qualify as an NDPS-controlled substance, triggering two independent permit regimes; arrival at port without the Rule 53 NDPS import certificate — even where the CIB&RC permit is current — results in detention and potential seizure under the NDPS Act, 1985.
