Compliance steps

1
Where heptene figures 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 filing the bill of entry. Import is permitted only at places specified under Rule 45 of the Insecticides Rules, 1971; consignments routed through unspecified ports are liable to detention.

2
If the substance is classified as an NDPS, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 for imports intended for medical or scientific purposes. All other NDPS imports are governed by Appendix-I to the ITC (HS) Schedule and require prior DGFT authorisation.

3
Comply with CBIC Circular 23/2023-Cus dated 30-09-2023 by furnishing mandatory additional qualifiers in the import declaration for Chapter 29 commodities, with effect from 15 October 2023. Additionally, where the quantity of heptene exceeds the specified threshold as a hazardous substance, the owner must obtain a public liability insurance policy under the provisions of S.O. 227(E) dated 24-03-1992.

A word of counsel

The critical error on this tariff line is assuming that because heptene is a general acyclic hydrocarbon, neither the Insecticides Act nor the NDPS regime is triggered. Both regimes are schedule-driven: the obligation to obtain CIB&RC registration and an import permit, or an NDPS import certificate, arises only if the substance appears in the relevant schedule — but customs will not grant out-of-charge until the importer affirmatively demonstrates non-applicability or provides the requisite permit. Importers who arrive at the port of entry without this determination made in advance face detention and demurrage while the classification is resolved.

Frequently asked

Does HSN 2901 29 20 require BIS certification?

No. No BIS Quality Control Order covers acyclic hydrocarbons such as heptene. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with concurrent NDPS Rules, 1985 conditions and DGFT ITC (HS) policy condition 2 of Chapter 29.

Are there port restrictions for importing heptene under the Insecticides Act regime?

Yes. Where the substance falls within the Schedule to the Insecticides Act, 1968, import is restricted to places specified under Rule 45 of the Insecticides Rules, 1971; the permitted ports should be verified with CIB&RC before placing the purchase order.

What happens if heptene is imported for medical or scientific purposes under the NDPS regime but without a Rule 53 import certificate?

Import without the Rule 53 import certificate constitutes an unauthorised import of an NDPS substance, attracting seizure and criminal liability under the Narcotic Drugs and Psychotropic Substances Act, 1985; the NDPS Rules admit no post-clearance regularisation for this category.
