Compliance steps

1
Obtain CIB&RC registration under Section 9 of the Insecticides Act, 1968 before import where the substance is intended for insecticidal, fungicidal, herbicidal, or rodenticidal use; where imported for a non-insecticidal purpose, obtain a separate import permit from the Registration Committee. Confirm that the source of import matches the source specified on the registration certificate or permit — import from any other source is prohibited.
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 only through the places notified for insecticide import under Rule 45 of the Insecticides Rules, 1971. Arrival at an unauthorised port of import renders the consignment liable to detention and regulatory action under the Insecticides Act, 1968.
Rule 45 of the Insecticides Rules, 1971 · Court Order 2002 (146) ELT 19 (SC)
3
File the bill of entry with the mandatory additional qualifiers for Chapter 28 commodities as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-CUS. Where the quantity of hazardous substance exceeds the specified threshold, the owner must hold a valid Public Liability Insurance policy per S.O. 227(E) dated 24-03-1992 issued by the Ministry of Environment and Forests.

A word of counsel

The most common error on this residual sulphate line is treating an absence of declared insecticidal end-use as an exemption from all CIB&RC requirements. The Insecticides Act, 1968 requires an import permit from the Registration Committee even where the substance is imported for non-insecticidal purposes — the permit obligation is not limited to registered insecticides. Consignments arriving without either a registration certificate or a non-insecticidal-purpose permit are detained at the notified port, and source-specificity on the existing certificate must be verified before each shipment.

Frequently asked

Does HSN 2833 19 90 require BIS certification?

No, this residual sulphates tariff line falls outside the BIS Quality Control Order regime. Import is governed by the Central Insecticides Board and Registration Committee under Section 9 of the Insecticides Act, 1968, with CBIC Chapter 28 declaration qualifiers applicable from 15 October 2023.

Does the CIB&RC permit requirement apply even when the sulphate is not used as an insecticide?

Yes. Where the substance is imported for a non-insecticidal purpose, a separate import permit from the Registration Committee under the Insecticides Act, 1968 is required, distinct from the registration certificate issued for insecticidal-use imports.

What triggers the Public Liability Insurance requirement for this HSN?

Import of specified hazardous substances exceeding the quantities prescribed under S.O. 227(E) dated 24-03-1992 by the Ministry of Environment and Forests requires the owner to maintain a Public Liability Insurance policy under the Public Liability Insurance Act, 1991.
