CIB&RC CLEARANCE

HSN 2837 19 90 (Other cyanides and complex cyanides) is subject to mandatory registration or import permit requirements administered by the Central Insecticides Board and Registration Committee (CIB&RC) 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 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 in import declarations apply as an additional customs overlay.

Compliance steps

1
Obtain CIB&RC registration under Section 9 of the Insecticides Act, 1968 if the cyanide is imported for insecticidal, rodenticidal, fungicidal, or herbicidal use; obtain a CIB&RC import permit if the substance is imported for a non-insecticidal purpose. Import is permitted only from the source specified on the certificate of registration or the permit — no substitution of source is allowed.
Section 9 of the 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 place of import permitted under Rule 45 of the Insecticides Rules, 1971. Entry through any non-notified port of import renders the consignment liable to detention and enforcement action under the Insecticides Act, 1968.
Rule 45 of the Insecticides Rules, 1971 · Court Order 2002 (146) ELT 19 (SC)
3
Ensure the import declaration includes the mandatory additional qualifiers for Chapter 28 commodities as stipulated in Para 4.1 and 4.2 of CBIC Circular 23/2023-Cus dated 30-09-2023, effective from 15 October 2023. Additionally, if the hazardous substance quantity exceeds the specified threshold, the importer must obtain a public liability insurance policy under the provisions of the PLI Act, 1991.

A word of counsel

The most common error on this tariff line is presenting a CIB&RC registration certificate issued for an insecticidal end-use when the actual import is for a non-insecticidal industrial purpose — or vice versa. The two tracks carry different documentary requirements: an insecticidal import requires registration under Section 9, while a non-insecticidal import requires a separate import permit from the Registration Committee. Mismatching the declared end-use against the authorisation held triggers consignment detention and may attract prosecution under the Insecticides Act, 1968.

Frequently asked

Does HSN 2837 19 90 require BIS certification?

No. No BIS Quality Control Order covers this cyanide product family. Import is governed by the Central Insecticides Board and Registration Committee under Section 9 of the Insecticides Act, 1968, with CBIC mandatory Chapter 28 declaration qualifiers applying at the bill-of-entry stage.

Can the importer substitute the source of supply after CIB&RC registration is granted?

No. The certificate of registration or import permit issued by the Registration Committee specifies the permitted source of import, and no cyanide may be imported from any other source — a source change requires a fresh or amended authorisation from CIB&RC.

What is the consequence of exceeding the specified quantity threshold for hazardous substances under this HSN?

Where the imported quantity of the specified hazardous substance exceeds the prescribed threshold, the owner is required to take out a public liability insurance policy under the PLI Act, 1991, as notified by S.O. 227(E) dated 24-03-1992.
