Compliance steps

1
Determine whether the specific formulation or substance falls within the Schedule to the Insecticides Act, 1968. If it does, obtain registration and an import permit from the Secretariat of the Central Insecticides Board and Registration Committee before shipment, and route the consignment only through ports notified under Rule 45 of the Insecticides Rules, 1971.

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

Ensure mandatory additional qualifiers are included in the import declaration at the bill of entry in compliance with CBIC Circular 23/2023-Cus dated 30-09-2023, applicable to commodities under Chapter 29 with effect from 15 October 2023. Where the consignment exceeds specified quantities of hazardous substances, take out an insurance policy under the Public Liability Insurance Act, 1991 as per S.O. 227(E) dated 24-03-1992.

A word of counsel

The most common error on this tariff line is assuming the substance does not fall within the Schedule to the Insecticides Act, 1968 and proceeding without CIB&RC registration — only to have the consignment detained at a port that is not notified under Rule 45 of the Insecticides Rules, 1971. The port-of-import restriction is a separate operative condition from the registration requirement; clearing registration but routing to an unnotified port remains an Insecticides Rules contravention. Additionally, the Chapter 29 mandatory qualifiers under CBIC Circular 23/2023-Cus are a customs-declaration obligation independent of PGA clearance, and omission draws bill-of-entry rejection.
