Compliance steps

Where the imported substance is an insecticide or is intended for insecticidal use, obtain mandatory registration or an import permit from CIB&RC under Section 9 of the Insecticides Act. The certificate of registration specifies the permitted source of import; no consignment may arrive from a source other than that specified on the certificate or permit.

A word of counsel

The most common error on this tariff line is importing for a non-insecticidal purpose without obtaining a separate CIB&RC import permit on that basis — importers assume that because the end-use is not pesticidal, the Insecticides Act is irrelevant. It is not: where any doubt exists as to end-use classification, the registration committee requires a non-insecticidal import permit, and shipping without one exposes the consignment to detention and seizure under the Insecticides Act regardless of the general free-import status confirmed by DGFT Notification 44/2025-26.

Frequently asked

Does HSN 2933 31 90 require BIS certification?

No; no BIS Quality Control Order covers pyridine salts or this organic-chemical product family. Import is governed by CDSCO registration where the substance is a listed medical device, CIB&RC registration or permit under the Insecticides Act, and NDPS policy conditions 2 and 3 where applicable.

Are there mandatory document codes or qualifier requirements at the bill of entry for Chapter 29 goods?

Yes. CBIC Circular 23/2023-Cus dated 30-09-2023 requires mandatory additional qualifiers in import declarations for Chapter 29 commodities under paragraphs 4.1 and 4.2, effective 15 October 2023; non-compliance results in the bill of entry being returned for amendment.
