Compliance steps

1
Confirm whether the substance falls within the schedule to the Insecticides Act, 1968; if so, obtain registration and an import permit from the secretariat of the Central Insecticides Board and Registration Committee before shipment. Import locations are restricted — verify permitted ports of import under Rule 45 of the Insecticides Rules, 1971.

A word of counsel

The most common error on this tariff line is treating CIB&RC and NDPS as alternative regimes and obtaining only one clearance. Where isobutyl benzene falls within the schedule to the Insecticides Act, 1968 and is also classifiable as an NDPS-controlled substance for the relevant end use, both a CIB&RC import permit and an NDPS import certificate under Rule 53 are independently required — the absence of either triggers consignment detention and potential seizure at the restricted port of import under Rule 45 of the Insecticides Rules, 1971.

Frequently asked

Does HSN 2902 90 50 require BIS certification?

No, isobutyl benzene falls outside the BIS Quality Control Order regime; no BIS QCO covers cyclic hydrocarbons under this tariff line. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with an NDPS overlay under the NDPS Rules, 1985 and DGFT ITC (HS) policy condition 2 of Chapter 29.

Are there port restrictions for importing isobutyl benzene under the Insecticides Act, 1968?

Yes. Rule 45 of the Insecticides Rules, 1971 restricts the places at which insecticides scheduled under the Insecticides Act, 1968 may be imported; the importer must confirm that the chosen port of entry is a notified permitted location before filing the bill of entry.

When does the public liability insurance requirement apply to imports of this substance?

Where import of specified hazardous substances exceeds the prescribed quantities, the owner is required to take out a public liability insurance policy under the provisions of S.O. 227(E) dated 24-03-1992 issued by the Ministry of Environment and Forests.
