CIB&RC CLEARANCE · NDPS CLEARANCE

HSN 2930 90 99 (other organo-sulphur compounds) is subject to Central Insecticides Board and Registration Committee (CIB&RC) registration and import permit under the Insecticides Act, 1968 and Rule 45 of the Insecticides Rules, 1971, where the substance falls within the Schedule to that Act. Narcotic Drugs and Psychotropic Substances (NDPS) import-certificate requirements under NDPS Rules, 1985 apply where substances such as 4-MTA are classified under this tariff line, and Chemical Weapons Convention (CWC) restrictions under ITC (HS) policy condition 3 of Chapter 29 govern scheduled chemical precursors. Mandatory Chapter 29 additional qualifiers under CBIC Circular 23/2023-Cus and Public Liability Insurance obligations under S.O. 227(E) dated 24-03-1992 apply as further overlays.

Compliance steps

1
Where the organo-sulphur compound falls within 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 specified under Rule 45 of the Insecticides Rules, 1971; ensure the consignment is routed only through a permitted port.

2
Where the substance is classified as an NDPS (e.g., 4-MTA), obtain an import certificate for medical or scientific use under Chapter VII-A of the NDPS Rules, 1985. For other uses, comply with ITC (HS) policy condition 2 to Chapter 29. Upload mandatory e-Sanchit documents — certificate of analysis (0010dc), batch release certificate (0030dc), and label of consignment (0110dc) — before out-of-charge.

A word of counsel

The most acute risk on this tariff line is the CWC overlay: Category 1A sulfur mustards and VX-class phosphonothiolates classified under this CTI are Restricted outright, not merely subject to a permit — and the prohibition extends to all possible combinations of alkyl groups listed in parentheses in the CWC schedule unless explicitly exempted. Category 1B chemicals such as amiton are permissible only from State Parties to the CWC subject to ITC (HS) policy condition 3 of Chapter 29; an importer who misreads the chemical name and files without verifying CWC schedule status faces confiscation and potential criminal liability under the Chemical Weapons Convention Act and Customs Act, 1962.

Frequently asked

Does HSN 2930 90 99 require BIS certification?

No. No BIS Quality Control Order covers this residual organo-sulphur compounds tariff line. Import is governed by CIB&RC registration and permit under the Insecticides Act, 1968, NDPS import-certificate requirements under the NDPS Rules, 1985 where a scheduled narcotic substance is involved, and CWC restrictions under ITC (HS) policy condition 3 of Chapter 29.

Which e-Sanchit documents are mandatory at the bill of entry for this CTI?

The certificate of analysis (document code 0010dc), batch release certificate (0030dc), and label of consignment (0110dc) must be uploaded in e-Sanchit before customs out-of-charge, per CBIC instructions for PGA-facilitated bills under this CTI.

Are all organo-sulphur compounds under this CTI subject to CIB&RC registration, or only specific substances?

CIB&RC registration and import permit are required only where the specific substance falls within the Schedule to the Insecticides Act, 1968; organo-sulphur compounds that do not appear in that Schedule are not subject to CIB&RC controls, though CWC, NDPS, and CBIC Chapter 29 qualifier obligations may independently apply.
