Compliance steps
  1. 1
    Where the imported 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. Route the consignment only through ports specified under Rule 45 of the Insecticides Rules, 1971; diversion to a non-specified port renders the import unauthorised.
    Insecticides Act, 1968 · Rule 45 of the Insecticides Rules, 1971
  2. 2
    Where the substance is an NDPS-scheduled compound, import is permitted solely for medical and scientific purposes under Chapter VII-A of the NDPS Rules, 1985 after obtaining an import certificate under Rule 53 of the NDPS Rules, 1985. Imports outside this category are governed by Appendix I to the ITC (HS) Schedule, per ITC (HS) policy condition 2 to Chapter 29.
    Rule 53 of the NDPS Rules, 1985 · ITC (HS) policy condition 2 to Chapter 29
  3. 3
    Comply with CBIC Circular 23/2023-Cus dated 30-09-2023 by including mandatory additional qualifiers in the import declaration for all commodities under Chapter 29, effective 15-10-2023. Additionally, verify CWC status: nitrogen mustards (Category 1A) require national authority permission, and Category 1B substances may be imported only from State Parties to the CWC.

A word of counsel

The most common error on this tariff line is treating the CTI as a single-regime entry and filing without first screening the specific substance against the Insecticides Act Schedule, the NDPS Rules schedule, and the CWC Appendix II categories. A consignment of a CWC Category 1A substance declared without prior national authority permission is subject to confiscation and criminal liability; the Chapter 29 mandatory qualifiers under CBIC Circular 23/2023-Cus are a separate and concurrent filing obligation that applies regardless of which PGA regime triggers.

Frequently asked
Does HSN 2921 44 90 require BIS certification?
No, no BIS Quality Control Order covers diphenylamine derivatives or their salts. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968 where the substance is scheduled, with concurrent NDPS and CWC policy overlays administered by DGFT for scheduled or controlled substances.
Which ports are permitted for import of insecticide substances under this tariff line?
Import of substances falling within the Schedule to the Insecticides Act, 1968 is restricted to ports specified under Rule 45 of the Insecticides Rules, 1971; the current list of notified ports must be confirmed with the CIB&RC Secretariat before placement of the purchase order.
What liability arises if specified hazardous substances are imported in quantities exceeding the prescribed threshold?
The owner must take out an insurance policy under the Public Liability Insurance Act, 1991, as stipulated by S.O. 227(E) dated 24-03-1992 issued by the Ministry of Environment and Forests; failure to do so constitutes a separate statutory contravention independent of the CIB&RC or NDPS regime.
