Compliance steps

1
Obtain CIB&RC registration under Section 9 of the Insecticides Act, 1968 if the sulphate compound is intended for insecticidal use, or an import permit from the Registration Committee under the Department of Agriculture and Cooperation if imported for a non-insecticidal purpose. The certificate or permit specifies the approved source of supply; import from any other source is not permitted.
Section 9, Insecticides Act, 1968 · Insecticides Rules, 1971 · CBIC Circulars 35/2011 dated 09-08-2011 and 7/2014 dated 07-03-2014
2
Route the consignment through a notified place of import as prescribed under Rule 45 of the Insecticides Rules, 1971. File the bill of entry with mandatory additional qualifiers for Chapter 28 commodities in the import declaration, in compliance with CBIC Circular 23/2023-Cus dated 30-09-2023, paragraphs 4.1 and 4.2, effective 15 October 2023.

A word of counsel

The most common error on this tariff line is importing under a CIB&RC registration or permit that names a specific foreign source and then switching to an alternative supplier without amending the certificate. Customs proper officers, guided by court order 2002(146)ELT 19 (SC), treat a source mismatch as a registration violation independent of whether the chemical composition is identical — the consignment is liable to detention and seizure. The Chapter 28 additional-qualifier obligation under CBIC Circular 23/2023-Cus is a separate bill-of-entry requirement and is not cured by a valid CIB&RC registration.

Frequently asked

Does HSN 2833 29 90 require BIS certification?

No, no BIS Quality Control Order covers this residual sulphates category. Import is governed by the Central Insecticides Board and Registration Committee under Section 9 of the Insecticides Act, 1968, where the substance has an insecticidal application, with CBIC mandatory-qualifier and public-liability-insurance overlays applying as additional requirements.

Is a CIB&RC import permit required even when the sulphate is not used as a pesticide?

Yes. Where an insecticidal-category chemical is imported for a non-insecticidal purpose, an import permit from the Registration Committee is still mandatory under the Insecticides Act, 1968; the permit documents the non-insecticidal end-use and the approved import source.

What happens if the consignment arrives at a port that is not a notified place of import under Rule 45 of the Insecticides Rules, 1971?

The consignment is liable to detention and cannot receive out-of-charge; diversion to a non-notified port constitutes a breach of the Insecticides Rules, 1971 and may attract seizure and monetary penalty under the Insecticides Act, 1968.
