Compliance steps

1
Obtain a certificate of registration or import permit from the Central Insecticides Board and Registration Committee before shipment. Where sulphoxide is imported for a non-insecticidal purpose, a separate import permit from the Registration Committee under the Department of Agriculture and Cooperation is required; importation from any source not specified on the certificate or permit is prohibited under Rule 45 of the Insecticides Rules, 1971.
Section 9 of the Insecticides Act, 1968 · Rule 45 of the Insecticides Rules, 1971 · CBIC Circulars 35/2011 dated 09-08-2011 and 7/2014 dated 07-03-2014
2
Where the consignment is classified as a drug or medical device under G.S.R. 102(E) dated 11-02-2020, ensure CDSCO registration is in place and upload the mandatory documents in e-Sanchit before filing the bill of entry: Certificate of Analysis — Drug (0010dc), Batch Release Certificate (0030dc), Label of Consignment (0110dc), Registration Certificate — Drugs (101dc1), and Import Licence for Drugs (9111dc).

Include all Chapter 29 mandatory additional qualifiers in the import declaration as required by paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus, with effect from 15 October 2023. If the consignment constitutes a specified hazardous substance exceeding the threshold quantity, take out an insurance policy under the Public Liability Insurance Act, 1991 per S.O. 227(E) dated 24-03-1992 issued by the Ministry of Environment, Forest and Climate Change.

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 signifying unrestricted import — it refers solely to the customs-policy classification and does not displace the CIB&RC registration or CDSCO drug-regime obligations, which are PGA-level requirements enforced independently. An importer who ships without a CIB&RC certificate or permit citing the 'free' policy status will face consignment detention and potential seizure under the Insecticides Act, 1968, regardless of basic customs compliance.

Frequently asked

Does HSN 2930 90 16 require BIS certification?

No, sulphoxide under this tariff line is not within the BIS Quality Control Order regime. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with concurrent CDSCO, MOHFW, and NDPS overlays depending on the end-use of the substance.

Which e-Sanchit document codes are mandatory for drug-use consignments under this HSN?

Where the substance is regulated as a drug or medical device, the following must be uploaded in e-Sanchit before out-of-charge: Certificate of Analysis — Drug (0010dc), Batch Release Certificate (0030dc), Label of Consignment (0110dc), Registration Certificate — Drugs (101dc1), and Import Licence for Drugs (9111dc).

Does the NDPS policy condition apply to all sulphoxide imports under this CTI?

Policy conditions 2 and 3 of Chapter 29 apply only where the specific sulphoxide substance is covered under the narcotic drugs and psychotropic substances schedule; importers should verify scheduling status before filing the bill of entry to determine whether the NDPS overlay is triggered.
