Compliance steps

1
Determine whether the specific substance being imported figures in the Schedule to the Insecticides Act, 1968. If it does, 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 also restricted to places notified under Rule 45 of the Insecticides Rules, 1971.

2
If the substance is a scheduled narcotic or psychotropic, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 before shipment. Imports other than those for medical and scientific purposes under Chapter VII-A of the NDPS Rules are governed by Appendix-I of the ITC (HS) Schedule per ITC (HS) policy condition no. 2 to Chapter 29.

A word of counsel

The most common error on this tariff line is failing to verify whether the specific heterocyclic compound being imported is scheduled under the Insecticides Act, 1968 before concluding that only DGFT policy conditions apply. CIB&RC registration and the port-restriction under Rule 45 of the Insecticides Rules, 1971 attach at the substance level — not the CTI level — meaning a consignment that is otherwise DGFT-policy-compliant will be detained if the substance is scheduled and no CIB&RC permit has been obtained. The CBIC Chapter 29 qualifier requirement under Circular 23/2023-Cus is a separate and concurrent obligation that applies regardless of PGA clearance status.

Frequently asked

Does HSN 2934 99 10 require BIS certification?

No. No BIS Quality Control Order covers this heterocyclic organic chemical. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968 where the substance is scheduled, with an NDPS overlay under the NDPS Rules, 1985 and DGFT ITC (HS) policy condition no. 2 to Chapter 29 for all imports.

Are all substances under CTI 2934 99 10 subject to CIB&RC registration?

No; CIB&RC registration and import permit are required only where the specific substance figures in the Schedule to the Insecticides Act, 1968. However, named substances including difenoconazole, dimethomorph, propiconazole and others listed in the CCR specifically require CIB&RC registration or import permit regardless of general scheduling status.

Does the NDPS import certificate requirement apply to all imports under this CTI?

No. The NDPS import certificate under Rule 53 of the NDPS Rules, 1985 applies only where the specific substance is a scheduled narcotic or psychotropic; imports for purposes other than medical and scientific use are governed by Appendix-I of the ITC (HS) Schedule per policy condition no. 2 to Chapter 29.
