2-(N,N-Diethylamino)ethanethiol, organo-sulphur chemical precursor
HSN 2930 60 00 (2-(N,N-Diethylamino)ethanethiol) is subject to Chemical Weapons Convention (CWC) Category 1B controls under Appendix II of the ITC (HS) import policy, permitting import only from State Parties to the CWC with mandatory post-import notification to the National Authority, Cabinet Secretariat, and DGFT within 30 days. The Central Insecticides Board and Registration Committee (CIB&RC) registration and permit apply where the substance figures in the Schedule to the Insecticides Act, 1968, and Narcotic Drugs and Psychotropic Substances (NDPS) Rules conditions govern any NDPS-classified import under Chapter VII-A of the NDPS Rules, 1985.
- Registration and import permit from CIB&RC
- CWC post-import notification to DGFT
- Chapter 29 mandatory qualifiers from CBIC
Procedural directions for customs clearance are issued by: Directorate General of Foreign Trade, Central Board of Indirect Taxes and Customs.
- 1Verify the country of export is a State Party to the Chemical Weapons Convention before placing the purchase order; import of CWC Category 1B chemical N,N-dialkyl aminoethane-2-thiols is prohibited from non-State Parties. Within 30 days of each import, notify consignment details to the National Authority CWC (Cabinet Secretariat), Ministry of External Affairs (D&ISA), Department of Chemicals and Petrochemicals, and DGFT, and submit a copy of the bill of entry to DGFT.Appendix II of the ITC (HS) Import Policy · CWC Act and Rules · Policy Condition 3 of Chapter 29
- 2Where the substance figures in the Schedule to the Insecticides Act, 1968, obtain registration and an import permit from the Secretariat of the Central Insecticides Board and Registration Committee before filing the bill of entry. Import is restricted to ports notified under Rule 45 of the Insecticides Rules, 1971; consignments arriving at non-notified ports are liable to seizure.Insecticides Act, 1968 · Rule 45 of the Insecticides Rules, 1971
- 3Comply with CBIC Circular 23/2023-Cus dated 30-09-2023 by including mandatory additional qualifiers in the import declaration for Chapter 29 commodities, as stipulated in paragraphs 4.1 and 4.2, with effect from 15-10-2023. Where import quantities exceed the specified thresholds under S.O. 227(E) dated 24-03-1992, take out a Public Liability Insurance policy under the Public Liability Insurance Act, 1991.CBIC Circular 23/2023-Cus dated 30-09-2023 · S.O. 227(E) dated 24-03-1992
The CWC Category 1B notification obligation is routinely missed because importers treat it as administrative rather than mandatory: failure to notify the National Authority, Ministry of External Affairs, Department of Chemicals and Petrochemicals, and DGFT within 30 days of each consignment constitutes a standalone breach of Policy Condition 3, Chapter 29 — independent of whether customs clearance was otherwise regular. Additionally, the CIB&RC registration requirement is triggered not by the HS classification alone but by whether the substance appears in the Schedule to the Insecticides Act, 1968; confirm that scheduling status with CIB&RC before the first shipment, as overlooking it exposes the consignment to confiscation and the importer to prosecution under the Insecticides Act.
