CIB&RC CLEARANCE · NDPS CLEARANCE

HSN 2921 42 90 (Other aniline derivatives and their salts) is subject to Central Insecticides Board and Registration Committee (CIB&RC) registration and import permit under the Insecticides Act, 1968, where the specific substance falls within the Schedule to that Act. Narcotic Drugs and Psychotropic Substances (NDPS) import-certificate conditions under Chapter VII-A of the NDPS Rules, 1985 apply where a substance meets the NDPS schedule criteria, and Chemical Weapons Convention (CWC) Category 1A and 1B precursor restrictions under Appendix II to Schedule I of the ITC (HS) policy govern nitrogen mustards and specified chloroalkylamine compounds.

Compliance steps

1
Where the imported substance is listed 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 shipment. Import is permissible only through ports notified under Rule 45 of the Insecticides Rules, 1971.

2
Where the substance qualifies as an NDPS scheduled item, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 for medical or scientific purposes; all other NDPS imports are governed by Appendix I to the ITC (HS) Schedule. Where the substance is a CWC Category 1A nitrogen mustard, import requires prior permission from the national authority; Category 1B chloroalkylamine compounds are permitted only from State Parties to the CWC subject to applicable conditions.

A word of counsel

The most common error on this tariff line is treating the CIB&RC registration as the sole gatekeeping obligation and overlooking the layered CWC and NDPS overlays that may independently restrict or prohibit the import of the same molecule. A substance can simultaneously fall outside the Insecticides Schedule, within a CWC Category 1B precursor list, and within the NDPS schedule — each trigger is assessed independently at the bill of entry, and a missing NDPS import certificate or an absent CWC national-authority permission results in detention and potential confiscation regardless of CIB&RC status.

Frequently asked

Does HSN 2921 42 90 require BIS certification?

No, no BIS Quality Control Order covers aniline derivatives and their salts under this tariff line. Import is governed primarily by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with concurrent NDPS and CWC precursor-control overlays under the ITC (HS) policy.

Are all aniline derivatives under this CTI subject to CIB&RC registration, or only specific substances?

CIB&RC registration and an import permit are required only where the specific substance figures in the Schedule to the Insecticides Act, 1968; substances not listed in that Schedule are not subject to CIB&RC controls, though CWC and NDPS overlays must still be assessed independently.

What happens if a consignment of a CWC Category 1A nitrogen mustard arrives without national authority permission?

Import of nitrogen mustards without prior permission from the national authority is a restricted-import violation under Appendix II to Schedule I (Category 1A) of the ITC (HS) policy, rendering the consignment liable to detention, seizure, and re-export or confiscation under the Customs Act, 1962.
