Compliance steps

1
Obtain a valid registration certificate or import permit from the Central Insecticides Board and Registration Committee before shipment. Where Isoprothiolane is imported for a non-insecticidal purpose, a separate import permit from the Registration Committee under the Department of Agriculture and Cooperation is required; no import may originate from a source not specified on the certificate or permit.
Section 9 of the Insecticides Act · Rule 45 of the Insecticides Rules, 1971 · CBIC Circular 35/2011 dated 09-08-2011 · CBIC Circular 7/2014 dated 07-03-2014
2
Submit mandatory additional qualifiers in the import declaration at the bill of entry stage, as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus, applicable to all commodities under Chapters 28, 29, 32, 39 and CTH 3808 with effect from 15-10-2023.

Where the substance is classified as a notified medical device under G.S.R. 102(E) dated 11-02-2020 issued by the Ministry of Health and Family Welfare, ensure full CDSCO registration compliance before filing the bill of entry. Additionally, where the consignment involves a specified hazardous substance exceeding the notified quantity, take out 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 CIB&RC registration as interchangeable with the non-insecticidal import permit. The two instruments are legally distinct: registration under Section 9 covers use as an insecticide, fungicide, or rodenticide, while import for any other declared purpose requires a separate permit — and the source-of-supply restriction on the certificate is independently enforced. Shipping from an unregistered or unlisted source, even with a current certificate in hand, renders the consignment liable to detention and seizure under the Insecticides Act regardless of any DGFT policy-condition compliance.

Frequently asked

Does HSN 2917 19 80 require BIS certification?

No, Isoprothiolane is not covered by any BIS Quality Control Order. Import is governed primarily by the Central Insecticides Board and Registration Committee under Section 9 of the Insecticides Act and Rule 45 of the Insecticides Rules, 1971, with a CDSCO overlay where the substance meets the notified medical-device criteria under G.S.R. 102(E) dated 11-02-2020.

Are there port restrictions on the import of Isoprothiolane under this tariff line?

Yes. Rule 45 of the Insecticides Rules, 1971 restricts the places at which insecticides may be imported; the permissible ports of import are specified on the CIB&RC registration certificate or import permit and cannot be varied without a fresh authorisation.

Do the NDPS policy conditions under Chapter 29 apply to Isoprothiolane?

Policy conditions 2 and 3 of Chapter 29 apply to all narcotic drugs and psychotropic substances covered under that chapter; whether Isoprothiolane falls within the scheduled substances should be confirmed against the NDPS schedules before filing the bill of entry, as misclassification attracts seizure and criminal liability under the NDPS framework.
