Compliance steps

1
Obtain a valid Certificate of Registration or import permit from the Central Insecticides Board and Registration Committee before shipment. Pendimethalin is a listed insecticide under Section 3(e) Schedule of the Insecticides Act, 1968; import from any source not specified on the registration certificate or permit is prohibited under Section 9 of the Act.
Section 9 of the Insecticides Act, 1968 · Rule 45 of the Insecticides Rules, 1971 · CBIC Circular 35/2011 dated 09-08-2011 · CBIC Circular 7/2014 dated 07-03-2014
2
Ensure all mandatory additional qualifiers for Chapter 29 commodities are included in the import declaration at bill of entry, with effect from 15 October 2023. Non-inclusion of qualifiers as specified in Para 4.1 and 4.2 attracts detention at the customs station.

A word of counsel

The most frequent error on this tariff line is importing on the strength of a CIB&RC registration that names a specific foreign source, then switching suppliers without updating the certificate — a change that renders the consignment an unauthorised import under Section 9 of the Insecticides Act, 1968, irrespective of whether the product is chemically identical. Additionally, importers using these active ingredients for non-insecticidal purposes (e.g., research or re-formulation) must separately secure an import permit from the Registration Committee; the standard insecticide registration does not cover non-insecticidal end-uses.
