CDSCO CLEARANCE · CIB&RC CLEARANCE · +3 OTHER PGAS

HSN 2934 10 90 (Other thiazole-ring heterocyclic compounds) is subject to Central Drugs Standard Control Organisation (CDSCO) registration under G.S.R. 102(E) dated 11-02-2020 where the compound qualifies as a listed medical device, and to Central Insecticides Board and Registration Committee (CIB&RC) registration or import permit under Section 9 of the Insecticides Act where the compound is intended for insecticidal, fungicidal, herbicidal, or rodenticidal use. Ozone-depleting-substance controls, hazardous-waste rules, and narcotic and psychotropic substance policy conditions apply as additional overlays administered by the Ministry of Environment, Forest and Climate Change (MEFCC), Ministry of Health and Family Welfare (MOHFW), and the Directorate General of Foreign Trade (DGFT).

Compliance steps

1
Determine the end-use category before filing the bill of entry. If the compound is a listed medical device, obtain CDSCO registration per G.S.R. 102(E) dated 11-02-2020 issued by MOHFW. If intended for insecticidal, fungicidal, herbicidal, or rodenticidal use, obtain CIB&RC registration or a non-insecticidal-purpose import permit; import is restricted to the source specified on the certificate of registration or permit under Section 9 of the Insecticides Act and Rule 45 of the Insecticides Rules, 1971.

2
Comply with CBIC Circular 23/2023-Cus dated 30-09-2023 and submit mandatory additional qualifiers in the import declaration for Chapter 29 commodities as stipulated in paragraphs 4.1 and 4.2, effective 15-10-2023. If the substance is a narcotic drug or psychotropic substance, ensure compliance with ITC (HS) policy conditions 2 and 3 of Chapter 29.

3
Where the substance is an ozone-depleting substance, satisfy policy conditions 1, 4, and 5 of Chapter 29 and comply with Para 8(a) of the General Notes of the ITC (HS) per the Ozone Depleting Substances (Regulation and Control) Rules, 2000. Where import involves hazardous waste, comply with Rules 12 and 13 of the Hazardous Waste (Management and Transboundary Movement) Rules, 2016 and Para 8(b) of the General Notes; quantities of specified hazardous substances exceeding notified thresholds require an insurance policy under the Public Liability Insurance Act, 1991 per S.O. 227(E) dated 24-03-1992.

A word of counsel

The most common error on this tariff line is treating the ITC (HS) 'Free' import status under DGFT Notification 44/2025-26 as a clearance to import without further formality. 'Free' denotes only that no separate DGFT licence is required; the multi-PGA overlay — CDSCO registration for medical-device-classified substances, CIB&RC registration or permit for agrochemical-use substances, NDPS policy conditions where the compound is a scheduled psychotropic substance, and the Chapter 29 mandatory qualifiers under CBIC Circular 23/2023-Cus — remains binding regardless of the import-policy classification. End-use misclassification at the bill-of-entry stage triggers detention and potential confiscation under the relevant Act.

Frequently asked

Does HSN 2934 10 90 require BIS certification?

No. No BIS Quality Control Order covers thiazole-ring heterocyclic compounds under this tariff line. Import is governed by CDSCO registration under G.S.R. 102(E) dated 11-02-2020 where the compound qualifies as a listed medical device, and by CIB&RC registration or permit under the Insecticides Act where intended for agrochemical use.

What happens if a thiazole compound classified here is used for non-insecticidal purposes but the importer lacks a CIB&RC non-insecticidal-purpose import permit?

Import without the required CIB&RC permit — even for a non-insecticidal end-use — constitutes a contravention of Section 9 of the Insecticides Act and Rule 45 of the Insecticides Rules, 1971, exposing the consignment to seizure and the importer to prosecution.

Are the Chapter 29 mandatory qualifiers under CBIC Circular 23/2023-Cus required for every import of this CTI?

Yes. CBIC Circular 23/2023-Cus dated 30-09-2023 requires mandatory additional qualifiers in import declarations for all commodities under Chapter 29 as specified in paragraphs 4.1 and 4.2, with effect from 15-10-2023; non-compliance results in bill-of-entry rejection at the gateway.
