CIB&RC CLEARANCE · NDPS CLEARANCE

HSN 2921 49 90 covers residual aromatic monoamine-function compounds subject to overlapping regimes: the Central Insecticides Board and Registration Committee (CIB&RC) requires registration and an import permit under the Insecticides Act, 1968 and Rule 45 of the Insecticides Rules, 1971 for any substance listed in the Insecticides Schedule. Narcotic Drugs and Psychotropic Substances (NDPS) controls apply where the substance falls within NDPS-classified compounds such as 4-fluoroamphetamine or eticyclidine, and Chemical Weapons Convention (CWC) Schedule I restrictions and ITC (HS) policy conditions administered by the Directorate General of Foreign Trade (DGFT) apply to nitrogen mustards and related precursors.

Compliance steps

1
Identify the specific substance within this residual CTI before filing the bill of entry. If the substance appears in the Schedule to the Insecticides Act, 1968, obtain registration and an import permit from the Secretariat of CIB&RC, and route the consignment only through ports permitted under Rule 45 of the Insecticides Rules, 1971.

2
Where the substance is an NDPS-classified compound (e.g., 4-fluoroamphetamine, eticyclidine), obtain an import certificate for medical or scientific use under Chapter VII-A of the NDPS Rules, 1985, or confirm compliance with ITC (HS) Schedule Appendix I and policy condition 2 to Chapter 29 for other permissible uses.

3
Upload mandatory e-Sanchit documents — certificate of analysis (0010dc), batch release certificate (0030dc), label of consignment (0110dc), registration certificate for drugs (101dc1), and import licence for drugs (9111dc) — before out-of-charge. Confirm compliance with CBIC Circular 23/2023-Cus dated 30-09-2023 by including mandatory Chapter 29 additional qualifiers in the import declaration effective 15 October 2023.

A word of counsel

The most common error on this residual CTI is filing a generic Chapter 29 declaration without identifying the specific compound first — this tariff line catches CWC Schedule I substances (nitrogen mustards, certain chloroethylamines), NDPS-classified compounds, and Insecticides-Schedule substances simultaneously, each triggering a distinct regulatory track. A consignment of a CWC Category IA substance from a non-State Party to the CWC is an unconditional prohibition; filing as a generic aromatic amine does not convert a Category IA precursor into a freely importable chemical, and the customs officer is required to verify compound identity against ITC (HS) Appendix II before granting out-of-charge.

Frequently asked

Does HSN 2921 49 90 require BIS certification?

No, residual aromatic monoamine-function compounds under this tariff line are not within any BIS Quality Control Order regime. Import is governed primarily by CIB&RC under the Insecticides Act, 1968 where the substance is a scheduled insecticide, with NDPS and CWC-derived ITC (HS) restrictions applying to controlled substances.

Are all compounds under CTI 2921 49 90 subject to CIB&RC registration, or only certain ones?

Only substances listed in the Schedule to the Insecticides Act, 1968 require CIB&RC registration and an import permit; importers must verify the specific compound against that Schedule and against ITC (HS) Appendices I and II before filing.

What happens if a CWC-controlled substance under this CTI is imported from a country that is not a State Party to the CWC?

Import of CWC Category IB substances such as N,N-dialkyl aminoethyl-2-chlorides is conditionally permitted only from State Parties to the CWC per Appendix II to Schedule I of the ITC (HS) policy; import from a non-State Party is not permitted and the consignment is liable to seizure and confiscation.
