Compliance steps
  1. 1
    Verify 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 must be routed through a port notified under Rule 45 of the Insecticides Rules, 1971.

  2. 2
    Where the substance is a scheduled NDPS substance, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 for imports covered by Chapter VII-A (medical and scientific purposes). Imports outside that category are governed by Appendix I to the ITC (HS) Schedule, administered by DGFT.

    Ensure the bill of entry includes the mandatory additional qualifiers for Chapter 29 commodities as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus, with effect from 15 October 2023. Where imports of specified hazardous substances exceed the prescribed quantities, obtain an insurance policy under the Public Liability Insurance Act, 1991 as per S.O. 227(E) dated 24-03-1992.

A word of counsel

The most common error on this tariff line is assuming that only one regulatory track applies: CIB&RC registration is triggered by the substance falling within the Insecticides Act schedule, while the NDPS overlay is triggered independently by scheduling under the NDPS Rules — both can apply simultaneously to the same consignment. An importer who secures only the CIB&RC permit without checking NDPS scheduling, or vice versa, risks detention and seizure at the port of import, because customs out-of-charge requires all applicable PGA clearances to be reflected in e-Sanchit before the bill of entry is assessed.

Frequently asked
Does HSN 2921 45 33 require BIS certification?
No, phenyl peri acid is not within the BIS Quality Control Order regime; no BIS QCO covers naphthylamine derivatives under Chapter 29. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with an NDPS overlay and DGFT ITC (HS) policy conditions applying concurrently.
Are there port restrictions on importing this substance under the Insecticides Rules?
Yes. Rule 45 of the Insecticides Rules, 1971 restricts import of insecticide-scheduled substances to specific notified ports; routing a consignment through an unnotified port exposes the importer to seizure and CIB&RC permit revocation.
What happens if the consignment also triggers the hazardous-substance insurance requirement?
Where the imported quantity of a specified hazardous substance exceeds the prescribed threshold, the owner must obtain an insurance policy under the Public Liability Insurance Act, 1991 as required by S.O. 227(E) dated 24-03-1992; failure to do so is a separate statutory contravention independent of CIB&RC or NDPS compliance.
