CIB&RC CLEARANCE · NDPS CLEARANCE

HSN 2921 19 90 (Other acyclic monoamines) carries a multi-regime import framework: the Central Insecticides Board and Registration Committee (CIB&RC) requires registration and an import permit for any substance falling in the Schedule to the Insecticides Act, 1968, while Chemical Weapons Convention (CWC) Category 1A nitrogen mustards are restricted under Section 15 of the CWC Act, 2000 and require prior permission from the National Authority. Narcotic Drugs and Psychotropic Substances (NDPS) controls 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 apply as additional overlays, alongside mandatory Chapter 29 qualifiers under CBIC Circular 23/2023-Cus.

Compliance steps

1
If the substance falls in the Schedule to the Insecticides Act, 1968, obtain registration and an import permit from the Secretariat of the Central Insecticides Board and Registration Committee before filing the bill of entry. Import is permitted only at ports specified under Rule 45 of the Insecticides Rules, 1971; routing through any other port renders the consignment liable to seizure.

2
If the substance is a CWC Schedule 1A nitrogen mustard (HN1, HN2, or HN3, including all possible di-alkylated combinations listed in the parenthetical groups), obtain prior permission from the National Authority under Section 15 of the Chemical Weapons Convention Act, 2000 before any import. Any NDPS-scheduled substance must be imported under an import certificate obtained under Rule 53 of the NDPS Rules, 1985, for medical or scientific purposes.
Section 15 of the CWC Act, 2000 · Rule 53 of the NDPS Rules, 1985 · ITC (HS) policy condition 2 to Chapter 29
3
Ensure all import declarations for goods under Chapter 29 include the mandatory additional qualifiers stipulated in Paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus with effect from 15 October 2023. Where the imported hazardous substance exceeds specified quantities, the owner must obtain an insurance policy under the Public Liability Insurance Act, 1991 per S.O. 227(E) dated 24-03-1992.

A word of counsel

The most consequential error on this tariff line is importing a CWC Schedule 1A nitrogen mustard — or a di-alkylated combination thereof — without National Authority permission on the assumption that the chemical name does not appear verbatim in the CWC schedule. The CWC Act, 2000 deems all combinations of alkyl groups from the parenthetical list to be prohibited unless explicitly exempted; a product whose IUPAC name differs superficially from HN1, HN2, or HN3 may still be captured, and import without permission constitutes a criminal offence under the CWC Act, 2000.

Frequently asked

Does HSN 2921 19 90 require BIS certification?

No, acyclic monoamines under this residual tariff line are not within the BIS Quality Control Order regime. Import is governed primarily by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with CWC, NDPS, and DGFT ITC (HS) policy overlays applying depending on the specific substance.

Which ports are permitted for importing insecticides classified under this HSN?

Import of substances falling in the Schedule to the Insecticides Act, 1968 is restricted to ports notified under Rule 45 of the Insecticides Rules, 1971; the current list of permitted import points should be confirmed with the CIB&RC Secretariat before dispatch.

Can NDPS-scheduled substances under this HSN be imported for research purposes?

Yes, but only under the special provisions for medical and scientific purposes in Chapter VII-A of the NDPS Rules, 1985, after obtaining an import certificate under Rule 53 of those Rules; imports outside that category are governed by Appendix I to the ITC (HS) Schedule per ITC (HS) policy condition 2 to Chapter 29.
