Compliance steps

1
If the consignment falls within 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. Import of scheduled insecticides is restricted to notified places of import under Rule 45 of the Insecticides Rules, 1971; diversion to an unnotified port renders the consignment liable to seizure.

2
Where the substance is classified as an NDPS substance, import for medical and scientific purposes must be accompanied by an import certificate obtained under Rule 53 of the NDPS Rules, 1985. Imports outside that category are governed by Appendix-I to the ITC (HS) Schedule and require prior DGFT authorisation.
Chapter VII-A of the NDPS Rules, 1985 · Rule 53 of the NDPS Rules, 1985 · ITC (HS) policy condition 2 of Chapter 29
3
Ensure the bill of entry includes all mandatory additional qualifiers required for Chapter 29 commodities under CBIC Circular 23/2023-Cus dated 30-09-2023, paragraphs 4.1 and 4.2, with effect from 15 October 2023. Where the import of specified hazardous substances exceeds notified threshold quantities, take out a public liability insurance policy under the provisions of 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 CIB&RC registration alone clears the consignment without verifying whether the substance also triggers the NDPS overlay or the hazardous-substance insurance obligation. These are three separate and independently enforceable regimes: a consignment that clears CIB&RC scrutiny may still be detained at the bill of entry if the NDPS import certificate under Rule 53 is absent, or if the Chapter 29 mandatory qualifiers required by CBIC Circular 23/2023-Cus are not uploaded in e-Sanchit before out-of-charge.

Frequently asked

Does HSN 2914 39 40 require BIS certification?

No. No BIS Quality Control Order covers dibenzanthrone or this organic-chemical product family. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968 and the NDPS regime under the NDPS Rules, 1985, with DGFT ITC (HS) policy condition 2 of Chapter 29 as the policy overlay.

Which ports are permitted for import of substances scheduled under the Insecticides Act, 1968?

Import of scheduled insecticides is restricted to notified places of import under Rule 45 of the Insecticides Rules, 1971; importers must confirm the notified-port list with the CIB&RC Secretariat before placing the purchase order.

What happens if the consignment qualifies as an NDPS substance but is not being imported for medical or scientific purposes?

Imports outside the medical and scientific use pathway under Chapter VII-A of the NDPS Rules, 1985 are governed by Appendix-I to the ITC (HS) Schedule; non-compliance with the applicable ITC (HS) condition renders the consignment liable to confiscation and prosecution under the NDPS Act.
