Compliance steps

1
Obtain registration and an import permit from the Secretariat of the Central Insecticides Board and Registration Committee before shipment if the substance falls within the schedule to the Insecticides Act, 1968.

A word of counsel

The most common error on this tariff line is treating CIB&RC clearance as the only gate and overlooking the CWC post-import notification requirement, which is a continuing obligation that arises after customs out-of-charge, not at the bill of entry. Failure to notify the National Authority and DGFT within 30 days of each import consignment constitutes a separate breach of the CWC Act and Rules and ITC (HS) Policy Condition 3, independent of whether the insecticide registration was in order at the port. Where an NDPS schedule overlap exists, the NDPS import certificate under Rule 53 must be secured before arrival, not concurrently with CIB&RC processing.

Frequently asked

Does HSN 2930 10 00 require BIS certification?

No, organo-sulphur compounds in this tariff line fall outside the BIS Quality Control Order regime; no BIS QCO covers this product family. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with CWC Category 1B chemical restrictions and NDPS controls as concurrent overlays.

Which ports are notified for import of insecticides under Rule 45 of the Insecticides Rules, 1971?

The places at which insecticides may be imported are restricted to those notified under Rule 45 of the Insecticides Rules, 1971; the current list should be confirmed with the CIB&RC Secretariat before placing the purchase order, as diversion to a non-notified port renders the consignment liable to seizure.

Does the Public Liability Insurance Act, 1991 apply to imports of this substance?

Yes, where the import quantity of this specified hazardous substance exceeds the threshold quantities prescribed under S.O. 227(E) dated 24-03-1992 issued by the Ministry of Environment and Forests, the owner is required to take out an insurance policy under the Public Liability Insurance Act, 1991.
