Compliance steps
  1. 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 is permitted only at ports notified under Rule 45 of the Insecticides Rules, 1971.

    Where the substance is an NDPS-scheduled material, obtain an import certificate under Rule 53 of the NDPS Rules, 1985, through the Central Bureau of Narcotics (cbn.nic.in). Where CWC-listed precursors (nitrogen mustards, Category 1A/1B) are involved, import is restricted to state parties to the CWC and requires permission from the national authority per Appendix II to Schedule I of the ITC (HS) policy.

A word of counsel

The most common error on this tariff line is treating CIB&RC registration as the only gate and overlooking the port-of-import restriction under Rule 45 of the Insecticides Rules, 1971. Consignments arriving at an unnotified port are liable to seizure irrespective of whether CIB&RC registration is current. Additionally, importers exceeding the specified quantities of hazardous substances must maintain a public liability insurance policy under the Public Liability Insurance Act, 1991, as notified by S.O. 227(E) dated 24-03-1992 — a requirement routinely missed at the bill-of-entry stage.

Frequently asked
Does HSN 2921 59 30 require BIS certification?
No, no BIS Quality Control Order covers this amine-function compound. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with NDPS Rules, 1985 and CWC national-authority controls as overlays.
Which ports are permitted for import of substances falling under the Insecticides Act, 1968?
Import of scheduled insecticides is restricted to notified places of import under Rule 45 of the Insecticides Rules, 1971; the current notified list should be confirmed with CIB&RC before booking the consignment.
Does the public liability insurance requirement apply to all imports under this tariff line?
No — the insurance obligation under the Public Liability Insurance Act, 1991 (S.O. 227(E) dated 24-03-1992) is triggered only when imports of specified hazardous substances exceed the specified quantities prescribed by the Ministry of Environment and Forests.
