Compliance steps
  1. 1
    Verify 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 before shipment, and note that import of insecticides is restricted to ports specified under Rule 45 of the Insecticides Rules, 1971.

  2. 2
    Where the substance qualifies as an NDPS item, import for medical or scientific purposes requires an import certificate under Rule 53 of the NDPS Rules, 1985 (Chapter VII-A). Imports outside that category are governed by Appendix-I to the ITC (HS) Schedule.

    Comply with CBIC Circular 23/2023-Cus dated 30-09-2023 by furnishing 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 of specified hazardous substances exceeds the quantities prescribed under S.O. 227(E) dated 24-03-1992, the owner must obtain an insurance policy under the Public Liability Insurance Act, 1991.

A word of counsel

The most common error on this tariff line is failing to verify, before shipment, whether the specific grade or formulation figures in the Schedule to the Insecticides Act, 1968 — importers assume the CIB&RC regime does not apply because the product is labelled as an industrial chemical rather than a pesticide. A scheduled substance imported without CIB&RC registration and permit, or routed through a non-notified port contrary to Rule 45 of the Insecticides Rules, 1971, is liable to seizure and prosecution regardless of whether an NDPS clearance or Chapter 29 CBIC qualifiers are otherwise in order.

Frequently asked
Does HSN 2901 24 00 require BIS certification?
No, acyclic hydrocarbons including buta-1,3-diene and isoprene are not subject to any BIS Quality Control Order. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with an NDPS Rules overlay for any substance qualifying under that regime and DGFT ITC (HS) policy condition 2 of Chapter 29.
Are imports of buta-1,3-diene and isoprene restricted to specified ports?
Yes, where the substance is scheduled under the Insecticides Act, 1968, import is restricted to ports notified under Rule 45 of the Insecticides Rules, 1971; routing through any other port renders the consignment liable to detention and seizure.
When does the Public Liability Insurance requirement apply to this tariff line?
It applies when the imported quantity of a specified hazardous substance exceeds the threshold prescribed under S.O. 227(E) dated 24-03-1992 issued by the Ministry of Environment and Forests, triggering mandatory insurance cover under the Public Liability Insurance Act, 1991.
