Compliance steps

1
If maleic anhydride 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, and route the consignment only through places notified under Rule 45 of the Insecticides Rules, 1971.

2
Where the consignment qualifies as an NDPS substance, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 for medical or scientific purposes, or confirm the import falls within Appendix-I to the ITC (HS) Schedule under policy condition 2 to Chapter 29 administered by DGFT.

3
Ensure the bill of entry includes the mandatory additional qualifiers for Chapter 29 commodities as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus, effective 15 October 2023. Additionally, where import quantities exceed specified thresholds for hazardous substances, take out an insurance policy under the Public Liability Insurance Act, 1991 per S.O. 227(E) dated 24-03-1992.

A word of counsel

The most common error on this tariff line is filing the bill of entry without the mandatory Chapter 29 qualifiers required under CBIC Circular 23/2023-Cus — an omission that triggers misdeclaration proceedings and consignment detention at customs, irrespective of whether CIB&RC or NDPS clearance is in order. Separately, importers frequently overlook the dual-track nature of the NDPS overlay: the medical/scientific-purpose route under Rule 53 of the NDPS Rules, 1985 is a distinct channel from the Appendix-I ITC (HS) commercial route, and conflating the two results in the import certificate being rejected at assessment.

Frequently asked

Does HSN 2917 14 00 require BIS certification?

No, maleic anhydride is not covered by any BIS Quality Control Order. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968 where the substance is Scheduled, with concurrent NDPS Rules, 1985 controls and DGFT ITC (HS) policy condition 2 to Chapter 29.

Are all imports of maleic anhydride subject to CIB&RC registration, or only specific uses?

CIB&RC registration and an import permit are required only where the substance figures in the Schedule to the Insecticides Act, 1968; the importer must verify the current Schedule listing before filing the bill of entry, as non-Scheduled formulations fall outside CIB&RC scope but remain subject to Chapter 29 CBIC qualifier requirements.

What happens if the consignment exceeds the specified quantity threshold for hazardous substances?

Where import quantities exceed the thresholds specified under S.O. 227(E) dated 24-03-1992, the owner is required to take out a public liability insurance policy under the Public Liability Insurance Act, 1991; failure to do so constitutes a violation of the Ministry of Environment and Forests notification and exposes the importer to detention and monetary penalty.
