2
Ensure the consignment is routed only through ports notified for insecticide imports under Rule 45 of the Insecticides Rules, 1971. Confirm compliance with ITC (HS) policy conditions 1, 2, 4 and 7 of Chapter 38 per DGFT Notification 45/2025-26 dated 15-10-2025; for formulation imports, refer to CBIC Circular 07/2014-Cus dated 07-03-2014.

3
Include all mandatory additional qualifiers in the import declaration for CTH 3808 commodities as required under paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus dated 30-09-2023, with effect from 15-10-2023.

A word of counsel

The most common error on this tariff line is overlooking the dual-track regime: Isoproturon may enter as a straightforward insecticide or herbicide formulation subject to Chapter 38 policy conditions, but where the product or its formulation appears in G.S.R. 102(E), it additionally requires CDSCO registration — and importers who ship without confirming this classification face consignment detention at the notified port until registration evidence is produced. The Chapter 38 mandatory qualifiers under CBIC Circular 23/2023-Cus are a separate, parallel requirement and non-inclusion causes bill-of-entry rejection independent of the CDSCO question.

Frequently asked

Does HSN 3808 91 33 require BIS certification?

No, no BIS Quality Control Order covers this product family. Import of Isoproturon is governed by CDSCO registration conditions under G.S.R. 102(E) dated 11-02-2020 where applicable, and by ITC (HS) policy conditions 1, 2, 4 and 7 of Chapter 38 administered by the Directorate General of Foreign Trade.

Which ports are permitted for import of Isoproturon insecticide formulations?

Import of insecticides is restricted to ports notified under Rule 45 of the Insecticides Rules, 1971; the active list of notified ports must be confirmed before vessel departure, as diversion to an unnotified port renders the consignment liable to detention and seizure.

Do the mandatory Chapter 38 qualifiers under CBIC Circular 23/2023-Cus apply to formulation imports of Isoproturon?

Yes. With effect from 15-10-2023, paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus require mandatory additional qualifiers in import declarations for all commodities under CTH 3808, including Isoproturon formulations; non-compliance results in bill-of-entry rejection at the assessment stage.
