Compliance steps

1
If the specific 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 notified places of import under Rule 45 of the Insecticides Rules, 1971; verify the permitted port of entry before placing the purchase order.

2
Where the substance qualifies as an NDPS substance, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 for medical and scientific-purpose imports under Chapter VII-A of those Rules. Imports outside this category are governed by Appendix I to the ITC (HS) Schedule per ITC (HS) policy condition 2 to Chapter 29.

3
Include all mandatory additional qualifiers in the import declaration at the bill of entry as stipulated in Paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus dated 30-09-2023, effective 15 October 2023. Where the consignment involves specified nitrogen mustards or N,N-dialkyl aminoethyl-2-chlorides, confirm the exporting country is a State Party to the Chemical Weapons Convention and that national authority permission has been obtained per Appendix II to Schedule I of the ITC (HS) policy.

A word of counsel

The most common error on this tariff line is filing a bill of entry without first determining which of the overlapping regimes — CIB&RC insecticides schedule, NDPS controlled-substance category, or CWC Schedule 1 chemical restriction — actually attaches to the specific molecular form being imported. Because the 8-digit CTI is a residual 'Other', customs officers verify substance identity against all three schedules simultaneously; a declaration that omits the Chapter 29 mandatory qualifiers required by CBIC Circular 23/2023-Cus will be held for amendment before out-of-charge, attracting demurrage and potential detention independent of any PGA clearance gaps.

Frequently asked

Does HSN 2921 11 90 require BIS certification?

No, no BIS Quality Control Order covers this product family. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, the NDPS Rules, 1985 for narcotic or psychotropic substances, and DGFT ITC (HS) policy controls for CWC-scheduled chemicals.

Are all ports open for import of substances under this CTI?

No. Where the substance is an insecticide falling within the schedule to the Insecticides Act, 1968, import is restricted to places notified under Rule 45 of the Insecticides Rules, 1971; import through any non-notified port renders the consignment liable to seizure.

What happens if the imported substance is a CWC Category 1 chemical and the exporting country is not a State Party to the Convention?

Import is not permitted. Appendix II to Schedule I of the ITC (HS) policy restricts Category 1A nitrogen mustards to national-authority-permitted imports and Category 1B N,N-dialkyl aminoethyl-2-chlorides solely to trade with State Parties to the Chemical Weapons Convention; consignments from non-State-Party origins are subject to confiscation.
