Compliance steps

1
If the substance falls within 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 shipment. Import of insecticides is restricted to ports notified under Rule 45 of the Insecticides Rules, 1971; routing through an unnotified port renders the consignment liable to detention and seizure.

2
For any substance that is a scheduled NDPS, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 before importation. Imports outside the medical and scientific purpose category are governed by Appendix I to the ITC (HS) Schedule per ITC (HS) policy condition 2 to Chapter 29.

A word of counsel

The critical trap on HSN 2921 59 90 is assuming the residual 'Other' description means no PGA scrutiny applies. Any substance within this heading that matches the Schedule to the Insecticides Act, 1968 triggers mandatory CIB&RC registration and port restriction independently of whether the NDPS or CWC overlay also applies — and all three regimes can apply simultaneously to a single shipment. Additionally, importers of specified hazardous substances exceeding threshold quantities must take out an insurance policy under the Public Liability Insurance Act, 1991 per S.O. 227(E) dated 24-03-1992, a requirement frequently overlooked at the bill-of-entry stage.

Frequently asked

Does HSN 2921 59 90 require BIS certification?

No, amine-function compounds under this residual tariff line are not subject to any BIS Quality Control Order. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with concurrent NDPS Rules and CWC-based ITC (HS) policy controls administered by DGFT where the specific substance is scheduled.

Are all imports under CTI 2921 59 90 subject to CIB&RC registration, or only certain substances?

CIB&RC registration and import permit are required only for substances that appear in the Schedule to the Insecticides Act, 1968; the import permit also determines the notified ports through which such substances may be imported under Rule 45 of the Insecticides Rules, 1971.

What happens if a CWC-controlled substance under Category 1B is imported from a non-State Party?

Import of N,N-dialkyl aminoethyl-2-chlorides and corresponding protonated salts is permitted only from State Parties to the Chemical Weapons Convention; a consignment originating from a non-State Party is subject to refusal of out-of-charge and may be liable to re-export or confiscation under the ITC (HS) Restricted policy administered by DGFT.
