Compliance steps

1
Obtain a Certificate of Registration or an import permit from the Central Insecticides Board and Registration Committee before shipment. Where the substance is imported for a non-insecticidal purpose, a separate import permit from the Registration Committee under the Department of Agriculture and Cooperation is required; the certificate must specify the permitted source of import, and no diversion from that source is permitted.

2
Route the consignment only through places notified under Rule 45 of the Insecticides Rules, 1971. File the bill of entry with the mandatory Chapter 28 additional qualifiers in the import declaration as stipulated in Para 4.1 and 4.2 of CBIC Circular 23/2023-Cus dated 30-09-2023, operative from 15 October 2023.

3
Where the imported quantity of a specified hazardous substance exceeds the threshold prescribed under the Public Liability Insurance Act, 1991, take out a public liability insurance policy before the consignment is cleared. Non-compliance with the insurance requirement is a distinct statutory contravention independent of the CIB&RC registration.

A word of counsel

The most common error on this tariff line is importing under a Certificate of Registration that specifies one source country and subsequently switching suppliers without obtaining a fresh certificate or amended permit — the registration is source-specific and any import from an unspecified source is treated as an unregistered import under the Insecticides Act, 1968, attracting seizure and prosecution. Verify that the source of supply on the registration certificate matches the bill of lading before placing the purchase order.

Frequently asked

Does HSN 2839 19 00 require BIS certification?

Is a separate permit needed if the silicate is imported for a non-insecticidal purpose?
