Compliance steps

1
Obtain registration and an import permit from the secretariat of the Central Insecticides Board and Registration Committee before filing the bill of entry, where ammonium perfluorooctane sulphonate figures in the Schedule to the Insecticides Act, 1968. Import is restricted to places notified under Rule 45 of the Insecticides Rules, 1971; routing to any non-notified port or place renders the consignment liable to seizure.

2
Where the substance is being imported for medical or scientific purposes under the NDPS framework, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 as per Chapter VII-A of those Rules. Imports outside the medical and scientific category are governed by Appendix-I to the ITC (HS) Schedule.
Chapter VII-A and Rule 53 of the NDPS Rules, 1985 · ITC (HS) policy condition 2 of Chapter 29
3
Ensure the import declaration includes the mandatory additional qualifiers for Chapter 29 commodities as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus, effective 15 October 2023. Where the import quantity of this specified hazardous substance exceeds the prescribed threshold, the owner must also take out an insurance policy under the Public Liability Insurance Act, 1991.

A word of counsel

The most common error on this tariff line is assuming that a valid CIB&RC registration alone completes the import clearance, without addressing the concurrent NDPS-framework conditions and the notified-port restriction under Rule 45 of the Insecticides Rules, 1971. A consignment arriving at a non-notified port is detainable regardless of registration status, and failure to include the Chapter 29 mandatory qualifiers in the import declaration — effective 15 October 2023 — attracts detention at the bill-of-entry stage under CBIC Circular 23/2023-Cus.

Frequently asked

Does HSN 2904 32 00 require BIS certification?

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

Which ports or places are notified for the import of insecticides under this tariff line?

Import of insecticides is restricted to places notified under Rule 45 of the Insecticides Rules, 1971; the current list should be confirmed with the CIB&RC secretariat before shipment, as consignments routed to non-notified locations are subject to detention and confiscation.

When does the Public Liability Insurance Act, 1991 obligation arise for this HSN?

The obligation arises when the import quantity of the specified hazardous substance exceeds the threshold prescribed under S.O. 227(E) dated 24-03-1992, at which point the owner must hold an insurance policy under the Public Liability Insurance Act, 1991 before the consignment is granted out-of-charge.
