Sulphinic acid
Sulphinic acid, organo-sulphur compound
HSN 2930 90 15 (Sulphinic acid) is subject to mandatory registration under Section 9 of the Insecticides Act, 1968 administered by the Central Insecticides Board and Registration Committee (CIB&RC), where the substance is imported for insecticidal or related pesticidal purposes, and an import permit from CIB&RC is required for non-insecticidal end-uses. Narcotic Drugs and Psychotropic Substances (NDPS) framework conditions under Chapter VII-A of the NDPS Rules, 1985, and Ministry of Environment, Forest and Climate Change (MEFCC) controls on hazardous substances and ozone-depleting substances apply as concurrent overlays, alongside CBIC mandatory Chapter 29 qualifier declarations effective 15 October 2023.

Procedural directions for customs clearance are issued by: Directorate General of Foreign Trade, Central Board of Indirect Taxes and Customs.
- 1Obtain a valid CIB&RC registration certificate (document code 101dc1) or import permit before filing the bill of entry. Where the substance is imported for a non-insecticidal purpose, obtain the import permit from the Registration Committee under the Department of Agriculture and Cooperation; the source of import must match exactly the source specified on the certificate or permit, and import at unspecified ports 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
- 2Upload all mandatory documents 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). Additionally, ensure the bill of entry includes the mandatory additional qualifiers for Chapter 29 commodities as stipulated in paras 4.1 and 4.2 of CBIC Circular 23/2023-Cus dated 30-09-2023, effective 15-10-2023.CBIC Circular 23/2023-Cus dated 30-09-2023 · e-Sanchit document codes 0010dc, 0030dc, 0110dc, 101dc1, 9111dc
- 3If the substance falls within the NDPS framework, import only for medical or scientific purposes under Chapter VII-A of the NDPS Rules, 1985 after obtaining an import certificate under Rule 53 of the NDPS Rules; imports outside that category are governed by Appendix-I to the ITC (HS) Schedule per ITC (HS) policy condition 2 to Chapter 29. If quantities of specified hazardous substances exceed notified thresholds, take out an insurance policy under the Public Liability Insurance Act, 1991 as required by S.O. 227(E) dated 24-03-1992.ITC (HS) policy condition 2 to Chapter 29 · Rule 53 of the NDPS Rules, 1985 · S.O. 227(E) dated 24-03-1992 · DGFT Notification 44/2025-26 dated 15-10-2025
The most common error on this tariff line is conflating the CIB&RC registration certificate — required where the substance is used as an insecticide, fungicide, herbicide, or rodenticide — with the import permit required for non-insecticidal end-uses; they are distinct instruments and an incorrect choice at the bill of entry triggers detention and potential confiscation under the Insecticides Act, 1968. Separately, the mandatory Chapter 29 additional qualifiers under CBIC Circular 23/2023-Cus are routinely omitted from import declarations for chemical intermediates, and missing qualifiers result in bills of entry being returned for amendment, accruing demurrage.
