Compliance steps

1
If the substance imported under this CTI 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. Route the consignment only through ports specified under Rule 45 of the Insecticides Rules, 1971; import through any other port is not permitted.
Insecticides Act, 1968 · Rule 45 of the Insecticides Rules, 1971
2
For substances qualifying as NDPS, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 for medical and scientific purposes before filing the bill of entry. Imports outside the medical and scientific category are governed by Appendix I to the ITC (HS) Schedule per ITC (HS) policy condition 2 to Chapter 29.
Chapter VII-A of the NDPS Rules, 1985 · Rule 53 of the NDPS Rules, 1985 · ITC (HS) policy condition 2 to Chapter 29
3
Comply with CBIC Circular 23/2023-Cus dated 30-09-2023 by submitting 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. Nitrogen mustards and CWC Schedule I(Cat IA) substances require national authority permission; Category IB substances may be imported only from State Parties to the CWC subject to applicable ITC (HS) conditions.

A word of counsel

The single most common error on this tariff line is filing the bill of entry without the mandatory Chapter 29 qualifiers required under CBIC Circular 23/2023-Cus, which triggers examination and detention independently of whether CIB&RC or NDPS clearances are in order. Additionally, importers frequently overlook the Public Liability Insurance obligation: where a specified hazardous substance is imported in quantities exceeding the prescribed threshold, an insurance policy must be taken out under the Public Liability Insurance Act, 1991 per S.O. 227(E) dated 24-03-1992, and its absence constitutes a separate breach at the bill-of-entry stage.

Frequently asked

Does HSN 2921 30 90 require BIS certification?

No, no BIS Quality Control Order covers this product family of cyclanic and cyclenic polyamines. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with NDPS, CWC Schedule I, and DGFT ITC (HS) policy overlays where the specific substance triggers those regimes.

Which ports are permitted for import of insecticide-scheduled substances under this CTI?

Import of insecticides is restricted to notified ports under Rule 45 of the Insecticides Rules, 1971; the current list of designated ports should be confirmed with the CIB&RC Secretariat before shipment, as diversion to an unlisted port exposes the consignment to detention and seizure.

Does the CWC restriction on nitrogen mustards apply to all substances under this residual CTI?

No. The CWC Schedule I (Cat IA) restriction on nitrogen mustards and the Cat IB restriction on specified chlorinated ethylamine compounds apply only to those specific chemicals; other cyclanic or cycloterpenic amines under this residual CTI are not subject to the CWC overlay but remain subject to CIB&RC and NDPS checks where applicable.
