Compliance steps

1
Determine whether the specific substance falls within the Schedule to the Insecticides Act, 1968. If so, obtain registration and an import permit from the secretariat of the Central Insecticides Board and Registration Committee, and route the consignment only through ports permitted under Rule 45 of the Insecticides Rules, 1971.

2
If the substance is an NDPS-scheduled compound, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 for medical or scientific purposes, or confirm compliance with Appendix I to the ITC (HS) Schedule per ITC (HS) policy condition 2 to Chapter 29. Nitrogen mustards and specified aminoethyl chlorides require CWC national-authority permission and are permitted only from State Parties to the CWC.
Chapter VII-A of the NDPS Rules, 1985 · Rule 53 of the NDPS Rules, 1985 · Appendix II to Schedule I (Cat 1A and Cat 1B) of ITC (HS) policy · ITC (HS) policy condition 2 to Chapter 29
3
File the bill of entry with mandatory additional qualifiers for Chapter 29 commodities as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus. Where import quantity of a specified hazardous substance exceeds the prescribed threshold, take out a public liability insurance policy under the Public Liability Insurance Act, 1991.

A word of counsel

The most common error on this tariff line is filing the bill of entry without first screening whether the declared substance triggers any of the three parallel regimes — CIB&RC schedule, NDPS schedule, and CWC Appendix — since a substance may fall under more than one simultaneously. CIB&RC port restrictions under Rule 45 of the Insecticides Rules, 1971 are frequently overlooked, and a consignment routed to an unpermitted port is detained regardless of whether the registration certificate is otherwise current.

Frequently asked

Does HSN 2921 41 90 require BIS certification?

No, no BIS Quality Control Order covers this organic-chemicals tariff line. Import is governed by Central Insecticides Board and Registration Committee registration and permit requirements under the Insecticides Act, 1968, with concurrent NDPS and CWC-based ITC (HS) policy overlays where the specific substance is scheduled.

Are all aniline derivatives under this CTI subject to CIB&RC permit requirements?

Only substances that figure in the Schedule to the Insecticides Act, 1968 require CIB&RC registration and an import permit; substances outside that Schedule are not subject to CIB&RC controls, though NDPS and CWC conditions may still apply independently.

What happens if the declared substance is both an NDPS-scheduled compound and a CWC-listed chemical?

Both regimes apply concurrently: an NDPS import certificate under Rule 53 of the NDPS Rules, 1985 and CWC national-authority permission are each independently required, and the import must additionally comply with the relevant Appendix conditions of the ITC (HS) policy for Chapter 29.
