CIB&RC CLEARANCE

HSN 2839 90 90 (other silicates and commercial alkali metal silicates) is subject to Central Insecticides Board and Registration Committee (CIB&RC) registration or import permit under Section 9 of the Insecticides Act, 1968, where the substance is intended for use as an insecticide, rodenticide, fungicide, or herbicide. For non-insecticidal end-uses, a separate import permit from the Registration Committee under the Department of Agriculture and Cooperation is required. Central Board of Indirect Taxes and Customs (CBIC) mandatory Chapter 28 qualifiers under Circular 23/2023-CUS apply as an additional customs overlay.

Compliance steps

1
Obtain registration from the Central Insecticides Board and Registration Committee under Section 9 of the Insecticides Act, 1968 if the substance is imported for insecticidal use, or an import permit from the Registration Committee if imported for a non-insecticidal purpose. The certificate or permit will specify the approved source of import; no import from an unapproved source is lawful.

2
File mandatory additional qualifiers in the import declaration for Chapter 28 commodities as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-CUS, effective 15 October 2023. Missing or incorrect qualifiers attract examination and potential detention at the bill-of-entry stage.

A word of counsel

The most common error on this tariff line is assuming that a CIB&RC certificate of registration for one declared end-use — say, fungicidal application — covers a consignment also intended for a non-insecticidal industrial use, or vice versa. The Act treats insecticidal and non-insecticidal uses as distinct licensing tracks, and a source-of-import deviation from the approved source named on the certificate or permit is independently actionable, regardless of whether the product itself is compliant. Confiscation, monetary penalty, and prosecution under the Insecticides Act, 1968 may all attach simultaneously.

Frequently asked

Does HSN 2839 90 90 require BIS certification?

No. No BIS Quality Control Order covers this residual silicates tariff line. Import is governed by the Central Insecticides Board and Registration Committee under Section 9 of the Insecticides Act, 1968 — registration for insecticidal use or an import permit for non-insecticidal use — along with CBIC Chapter 28 mandatory qualifier requirements.

Is the import of substances under this HSN restricted to specific ports of entry?

Yes. The places at which insecticides may be imported are restricted under Rule 45 of the Insecticides Rules, 1971, as confirmed by court order 2002(146)ELT 19 (SC) and CBIC Circulars 35/2011 and 7/2014; importers must route consignments only through the notified entry points.

What happens if the substance is imported from a source not named on the CIB&RC certificate or permit?

Import from an unapproved source is unlawful regardless of the substance's composition; the consignment is liable to seizure and the importer faces prosecution under the Insecticides Act, 1968, because the approved source is a condition of the registration or permit itself.
