Thiuram mono-, di or tetrasulphides (organo-sulphur compounds)

CIB&RC CLEARANCE · NDPS CLEARANCE

HSN 2930 30 00 (Thiuram mono-, di or tetrasulphides) is subject to Central Insecticides Board and Registration Committee (CIB&RC) registration and import permit under the Insecticides Act, 1968, where the substance falls within its Schedule. Narcotic Drugs and Psychotropic Substances (NDPS) import-certificate conditions and Chemical Weapons Convention (CWC) National Authority permissions apply as concurrent overlays for scheduled substances within this tariff line, and the ITC (HS) policy administered by the Directorate General of Foreign Trade (DGFT) classifies certain sub-categories as Restricted.

Compliance steps

1
Confirm whether the specific thiuram compound falls within the Schedule to the Insecticides Act, 1968. If it does, obtain registration and an import permit from the Secretariat of CIB&RC before shipment, and note that import is restricted to specified places under Rule 45 of the Insecticides Rules, 1971.

2
If the substance is scheduled under the NDPS Rules, 1985, obtain an import certificate under Rule 53 of the NDPS Rules before filing the bill of entry. For CWC-scheduled substances (Category 1A sulfur mustards or Category 1B thiodiglycol analogues), secure permission from the National Authority and confirm the exporting country is a CWC State Party.
Rule 53 of NDPS Rules, 1985 · Appendix II to Schedule I (Cat 1A and Cat 1B) of ITC (HS) policy · ITC (HS) policy condition no. 2 to Chapter 29
3
Ensure the import declaration includes the mandatory additional qualifiers for Chapter 29 commodities as stipulated in Para 4.1 and 4.2 of CBIC Circular 23/2023-Cus dated 30-09-2023, operative from 15 October 2023. If the consignment exceeds specified hazardous-substance quantities, an insurance policy under the Public Liability Insurance Act, 1991 is required per S.O. 227(E) dated 24-03-1992.

A word of counsel

The most common error on this tariff line is assuming a single clearance pathway covers the entire CTI. Thiuram tetrasulphide used as a pesticide requires CIB&RC registration and a port-of-import restriction under Rule 45 of the Insecticides Rules, 1971, while a thiuram compound that also qualifies as a CWC-scheduled substance requires a separate National Authority permission — and both obligations operate independently. Shipping to an unspecified port, or filing without the Chapter 29 mandatory qualifiers, attracts detention and CBIC monetary penalty regardless of whether PGA clearance is in order.

Frequently asked

Does HSN 2930 30 00 require BIS certification?

No, organo-sulphur compounds under this tariff line are not covered by any BIS Quality Control Order. Import is governed primarily by CIB&RC under the Insecticides Act, 1968, with concurrent NDPS and CWC National Authority overlays for scheduled substances and DGFT ITC (HS) Restricted-import conditions.

Which ports are approved for import of insecticide-scheduled substances under this HSN?

Import of insecticides listed in the Schedule to the Insecticides Act, 1968 is restricted to specified places as notified under Rule 45 of the Insecticides Rules, 1971; the current approved-port list should be confirmed with the CIB&RC Secretariat before placing the purchase order.

Does the NDPS import-certificate requirement apply to all thiuram compounds or only specific substances?

Only substances that fall within the schedules governed by the NDPS Rules, 1985 require an import certificate under Rule 53; the NDPS and CWC overlays are substance-specific and do not apply to thiuram compounds outside those schedules, as confirmed by ITC (HS) policy condition no. 2 to Chapter 29.
