Compliance steps

1
Verify whether the consignment falls within the Schedule to the Insecticides Act, 1968; if so, obtain registration and an import permit from the Secretariat of the Central Insecticides Board and Registration Committee before shipment. Import is also restricted to ports notified under Rule 45 of the Insecticides Rules, 1971. Upload the registration certificate (document code 101dc1) and import licence for drugs (document code 9111dc) in e-Sanchit before the bill of entry is filed.

2
If the substance qualifies as an NDPS import for medical or scientific purposes, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 via the Central Bureau of Narcotics (cbn.nic.in). Imports outside the medical/scientific category are governed by Appendix-I to the ITC (HS) Schedule.

Ensure compliance with CBIC Circular 23/2023-Cus dated 30-09-2023: mandatory additional qualifiers in the import declaration for Chapter 29 commodities (per Paragraphs 4.1 and 4.2) are required with effect from 15-10-2023. Additionally, where the import quantity exceeds specified thresholds for hazardous substances, 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 failing to check the Schedule to the Insecticides Act, 1968 before relying solely on the NDPS import certificate. The two regimes are independent: a valid NDPS certificate does not satisfy CIB&RC registration requirements, and the port-restriction under Rule 45 of the Insecticides Rules, 1971 applies regardless of which PGA clearance is in hand. Consignments arriving at a non-notified port without CIB&RC permit are liable to detention and seizure even where NDPS documentation is complete.

Frequently asked

Does HSN 2935 30 00 require BIS certification?

No; no BIS Quality Control Order covers this sulphonamide. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968 and, where the substance is scheduled under NDPS, by the NDPS Rules, 1985 administered through the Central Bureau of Narcotics.

Which document codes must be uploaded in e-Sanchit for this tariff line?

The registration certificate (document code 101dc1) and import licence for drugs (document code 9111dc) must be uploaded in e-Sanchit before customs out-of-charge is granted, per the PGA-facilitated-bill verification requirement.

Does the mandatory Chapter 29 qualifier requirement apply to this HSN?

Yes. CBIC Circular 23/2023-Cus dated 30-09-2023 requires mandatory additional qualifiers in import declarations for all Chapter 29 commodities with effect from 15 October 2023; non-compliance renders the import declaration deficient at the bill-of-entry stage.
