A word of counsel

The most common error on this tariff line is assuming that only one of the two primary-regulator tracks — CIB&RC or NDPS — applies and neglecting the other. Whether a consignment triggers CIB&RC registration depends on Schedule-listing verification, which must be completed before purchase-order placement; arriving at a non-notified port with a valid CIB&RC permit is itself a breach of Rule 45 of the Insecticides Rules, 1971 and exposes the consignment to detention and seizure independent of whether the permit is otherwise current.

Frequently asked

Does HSN 2904 33 00 require BIS certification?

No, no BIS Quality Control Order covers lithium perfluorooctane sulphonate. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968 and Insecticides Rules, 1971, with overlapping NDPS Rules, 1985 conditions and the DGFT ITC (HS) policy condition no. 2 of Chapter 29.

Are there port restrictions for importing this substance under the Insecticides Rules?

Yes. Rule 45 of the Insecticides Rules, 1971 restricts import of scheduled insecticides to specified ports; the consignment must be routed through those ports, and diversion to an unspecified port renders the import unauthorised regardless of permit validity.

When does the public liability insurance requirement apply to this import?

Where lithium perfluorooctane sulphonate is imported as a specified hazardous substance in quantities exceeding the thresholds notified under S.O. 227(E) dated 24-03-1992, the importer must obtain a public liability insurance policy under the Public Liability Insurance Act, 1991 before the consignment clears customs.
