Compliance steps

1
Obtain registration and an import permit from the Central Insecticides Board and Registration Committee before shipping. Route the consignment only through a place notified under Rule 45 of the Insecticides Rules, 1971; import through any non-notified port or land customs station renders the consignment liable to seizure under the Insecticides Act, 1968.
Rule 45 of the Insecticides Rules, 1971 · DGFT Notification 45/2025-26 dated 15-10-2025 · ITC (HS) policy condition 7 of Chapter 29
2
Ensure all mandatory additional qualifiers required by CBIC Circular 23/2023-Cus are included in the import declaration at the bill of entry stage, as stipulated in paragraphs 4.1 and 4.2 of that circular with effect from 15 October 2023. Non-compliance at declaration stage attracts customs examination and potential detention.

3
Where the substance also attracts NDPS-regime controls, import is permissible for medical and scientific purposes only under Chapter VII-A of the NDPS Rules, 1985 after obtaining an import certificate under Rule 53 of the NDPS Rules; imports outside that category are governed by Appendix I to the ITC (HS) Schedule per ITC (HS) policy condition 2 of Chapter 29. Confirm whether the consignment triggers the Public Liability Insurance Act, 1991 threshold for hazardous substances; if so, an insurance policy under S.O. 227(E) dated 24-03-1992 is required.

A word of counsel

The most common error on this tariff line is treating the CIB&RC registration as sufficient and failing to verify that the port of import is among those specifically notified under Rule 45 of the Insecticides Rules, 1971. A consignment of Imazethapyr arriving at a non-notified customs station — even with a current CIB&RC permit — is liable to detention and seizure, and no post-arrival port change is available without fresh CIB&RC consent. Separately, the Chapter 29 chemical qualifiers mandated by CBIC Circular 23/2023-Cus must be populated in the bill of entry from the outset; a deficient declaration cannot be rectified after the examination order is issued.

Frequently asked

Does HSN 2933 39 22 require BIS certification?

No, no BIS Quality Control Order covers Imazethapyr or imidazolinone herbicides. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with NDPS-regime and DGFT ITC (HS) policy condition 7 of Chapter 29 as additional overlays.

Which ports or places are permitted for the import of Imazethapyr?

Import is restricted to places specifically notified under Rule 45 of the Insecticides Rules, 1971; the current notified list should be confirmed with CIB&RC before placing the purchase order, as shipment to any other customs station is not permissible regardless of the validity of the import permit.

When does the Public Liability Insurance requirement apply to this consignment?

Where the quantity of the imported hazardous substance exceeds the threshold specified under the Public Liability Insurance Act, 1991, the owner is required to take out an insurance policy as detailed in S.O. 227(E) dated 24-03-1992 issued by the Ministry of Environment and Forests.
