Compliance steps

1
Determine the end-use classification before filing the bill of entry: substances used as insecticides, herbicides, fungicides, or rodenticides require mandatory CIB&RC registration under Section 9 of the Insecticides Act, 1968; those imported for non-insecticidal purposes require a separate import permit from the Registration Committee. Import is restricted to sources specified on the certificate of registration or the permit, and import points are restricted under Rule 45 of the Insecticides Rules, 1971.
Section 9, Insecticides Act, 1968 · Rule 45, Insecticides Rules, 1971 · CBIC Circulars 35/2011 dated 09-08-2011 and 7/2014 dated 07-03-2014
2
If the substance is a listed medical device under G.S.R. 102(E) dated 11-02-2020, comply with all CDSCO registration conditions specified therein before the bill of entry is filed. Concurrently, ensure mandatory additional qualifiers are included in the import declaration for Chapter 29 commodities per paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus dated 30-09-2023, effective 15 October 2023.

Where the substance falls under DGFT policy condition 7 of Chapter 29 (applicable per DGFT Notification 44/2025-26 dated 15-10-2025 and the Finance Bill 2025 effective 01-05-2025), confirm compliance with that condition at the bill-of-entry stage. If the substance is a narcotic drug or psychotropic substance, policy conditions 2 and 3 of Chapter 29 also apply, and the import is subject to NDPS controls.

A word of counsel

The most common error on this tariff line is treating a single end-use classification as determinative when the same benzothiazole compound may trigger concurrent CIB&RC, CDSCO, and NDPS controls depending on its formulation and intended application. Methabenzthiazuron, for instance, is a listed insecticide under the Insecticides Act, 1968 and requires CIB&RC registration irrespective of the buyer's stated non-agricultural purpose; importing from an unregistered or unlisted source — even with a valid CDSCO credential — constitutes a separate Insecticides Act contravention attracting seizure and prosecution.

Frequently asked

Does HSN 2934 20 90 require BIS certification?

No, benzothiazole ring-system heterocyclic compounds are not covered by any BIS Quality Control Order. Import is governed by CDSCO registration where the substance qualifies as a listed medical device under G.S.R. 102(E) dated 11-02-2020, and by CIB&RC mandatory registration under the Insecticides Act, 1968 where the substance is used as an insecticide or herbicide.

Is the import-source restriction under the Insecticides Act relevant even for research or non-agricultural imports?

Yes. The Registration Committee's certificate of registration or import permit specifies the permitted source of supply, and no import from an unlisted source is lawful regardless of end-use. For non-insecticidal purposes, a separate import permit from the Registration Committee is required in place of full registration.

What additional obligations apply if the imported compound is a hazardous substance or waste?

If the substance is a specified hazardous substance imported in quantities exceeding prescribed thresholds, an insurance policy under the Public Liability Insurance Act, 1991 is required per S.O. 227(E) dated 24-03-1992; imports of waste are subject to Rules 12 and 13 of the Hazardous Waste (Management and Transboundary Movement) Rules, 2016 and General Note 8(b) of the ITC (HS) import policy.
