Compliance steps
  1. 1
    Determine whether the substance figures in the Schedule to the Insecticides Act, 1968.

A word of counsel

The most common error on this tariff line is treating CIB&RC and NDPS as mutually exclusive regimes and screening only for one. This compound may simultaneously attract the Insecticides Act, 1968 Schedule (requiring CIB&RC registration and a port-restricted import permit) and the NDPS Rules, 1985 overlay (requiring a separate import certificate under Rule 53); failing to screen for both before vessel departure risks detention at the port of import and potential confiscation under the respective Acts.

Frequently asked
Does HSN 2931 48 00 require BIS certification?
No, no BIS Quality Control Order covers this organo-phosphorus compound. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968 where the substance is Scheduled, with a concurrent NDPS Rules, 1985 overlay and DGFT ITC (HS) Appendix-II policy controls.
Are all ports of entry available for import under this tariff line?
No. Where the substance falls under the Schedule to the Insecticides Act, 1968, import is restricted to specified places only, as notified under Rule 45 of the Insecticides Rules, 1971; routing through an unspecified port renders the consignment liable to seizure.
What triggers the Public Liability Insurance requirement for this HSN?
Import of specified hazardous substances exceeding the quantities prescribed under S.O. 227(E) dated 24-03-1992 requires the owner to take out a Public Liability Insurance policy under the Public Liability Insurance Act, 1991 before clearance.
