Compliance steps

1
Obtain a valid registration and import permit from the secretariat of the Central Insecticides Board and Registration Committee for Trichlorfon as a scheduled insecticide under the Insecticides Act, 1968. Ensure the import is routed only through a place notified under Rule 45 of the Insecticides Rules, 1971.

2
Submit mandatory additional qualifiers in the import declaration for Chapter 29 commodities as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus, with effect from 15 October 2023. Non-submission of the required qualifiers renders the bill of entry non-compliant and liable to detention.

3
Verify whether the consignment falls under Appendix II of the ITC (HS) import policy and, if it attracts NDPS conditions, confirm that import is either covered by a medical or scientific-purpose import certificate under Rule 53 of the NDPS Rules, 1985 or is otherwise governed by Appendix I of the ITC (HS) Schedule per ITC (HS) policy condition 2 to Chapter 29.

A word of counsel

The most common error on this tariff line is filing the bill of entry against a CIB&RC registration alone without checking the NDPS overlay: Trichlorfon may independently figure in Appendix II of the ITC (HS) import policy, triggering a separate NDPS-conditions regime that demands an import certificate under Rule 53 of the NDPS Rules, 1985. An import that satisfies the CIB&RC regime but lacks the NDPS import certificate will be detained and may attract prosecution under the Narcotic Drugs and Psychotropic Substances Act, 1985. Additionally, importers of specified hazardous substances exceeding threshold quantities must maintain an insurance policy under the Public Liability Insurance Act, 1991 per S.O. 227(E) dated 24-03-1992.

Frequently asked

Does HSN 2931 54 00 require BIS certification?

No, Trichlorfon is not within the BIS Quality Control Order regime; no BIS QCO covers this organophosphate compound. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with an NDPS overlay and mandatory Chapter 29 qualifiers under CBIC Circular 23/2023-Cus.

Which ports or places are authorised for import of Trichlorfon?

Import of insecticides is restricted to places notified under Rule 45 of the Insecticides Rules, 1971; routing the consignment through a non-notified port or inland clearance depot exposes the importer to seizure and prosecution under the Insecticides Act, 1968.

When does the NDPS import certificate requirement apply to this HSN?

The NDPS import certificate under Rule 53 of the NDPS Rules, 1985 is required when the substance is identified as falling under Appendix II of the ITC (HS) import policy or is imported for medical or scientific purposes; importers should verify the current Appendix II schedule via the Central Bureau of Narcotics at cbn.nic.in before shipment.
