Compliance steps

1
Determine whether the specific acetal or hemiacetal substance is listed in the Schedule to the Insecticides Act, 1968. If listed, obtain registration and an import permit from the Secretariat of the Central Insecticides Board and Registration Committee, and route the consignment only through places notified under Rule 45 of the Insecticides Rules, 1971.

2
If the substance is an NDPS-scheduled item imported for medical or scientific purposes, obtain an import certificate under Rule 53 of the NDPS Rules, 1985. Imports outside that category are governed by Appendix-I to the ITC (HS) Schedule; consult the Central Bureau of Narcotics (cbn.nic.in) for the applicable sub-regime.

3
Comply with CBIC Circular 23/2023-Cus dated 30-09-2023 by including mandatory additional qualifiers in the import declaration for Chapter 29 commodities as stipulated in paragraphs 4.1 and 4.2, with effect from 15 October 2023. Where import quantities of specified hazardous substances exceed the threshold, 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 assuming that because a substance is not obviously a pesticide, neither the Insecticides Act nor CIB&RC registration applies. Several acetals and hemiacetals appear in the Schedule to the Insecticides Act, 1968 as inert ingredients or co-formulants; importers must check the Schedule before filing the bill of entry, because arrival at a non-notified port or without a CIB&RC permit constitutes a violation under the Act regardless of whether the substance was intended for pesticide use.

Frequently asked

Does HSN 2911 00 10 require BIS certification?

No, acetals and hemiacetals are 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 Schedule-listed, and by the NDPS Rules, 1985 where the substance is a narcotic or psychotropic substance.

Are all acetals under this CTI restricted to notified import ports?

The port restriction under Rule 45 of the Insecticides Rules, 1971 applies only to substances that figure in the Schedule to the Insecticides Act, 1968; substances not on the Schedule are not subject to that port restriction, though the DGFT ITC (HS) policy condition 2 of Chapter 29 and CBIC Chapter 29 qualifiers apply to all imports under this CTI.

What triggers the mandatory insurance requirement for hazardous substances under this tariff line?

Where the imported quantity of a specified hazardous substance exceeds the threshold prescribed under S.O. 227(E) dated 24-03-1992, the owner must take out an insurance policy under the Public Liability Insurance Act, 1991; failure to do so is a separate regulatory contravention independent of the CIB&RC or NDPS clearance.
