Compliance steps
  1. 1
    Verify whether the specific substance falls within the Schedule to the Insecticides Act, 1968. If so, obtain registration and an import permit from the secretariat of CIB&RC before shipment, and confirm the consignment is routed through a place notified for insecticide imports under Rule 45 of the Insecticides Rules, 1971.

  2. 2
    If the substance constitutes an NDPS item, secure an import certificate under Rule 53 of the NDPS Rules, 1985 before filing the bill of entry. Imports for medical and scientific purposes are governed by Chapter VII-A of the NDPS Rules, 1985; all other imports are subject to Appendix I to the ITC (HS) Schedule per ITC (HS) policy condition 2 to Chapter 29.

    Comply with CBIC Circular 23/2023-Cus dated 30-09-2023 by including the mandatory additional qualifiers in the import declaration for Chapter 29 commodities, as stipulated in paragraphs 4.1 and 4.2, with effect from 15 October 2023. Also ensure that imports of any CWC-scheduled nitrogen mustard or related compounds are sourced exclusively from State Parties to the CWC and are accompanied by the national authority permission per Appendix II to Schedule I of the ITC (HS) policy.

A word of counsel

The most common error on this tariff line is importing under a single clearance framework while the substance simultaneously engages a second regime — specifically, treating CIB&RC permit compliance as exhaustive when the consignment also carries NDPS scheduling or CWC Appendix II status. Each regime is independent: a valid CIB&RC permit does not satisfy the NDPS import certificate requirement under Rule 53, and a CWC-scheduled substance imported from a non-State Party faces confiscation regardless of other clearances. Confirm the substance's status under all three schedules before vessel departure.

Frequently asked
Does HSN 2921 45 32 require BIS certification?
No, this tariff line falls outside the BIS Quality Control Order regime; no BIS QCO covers naphthylamine derivatives. Import is governed by CIB&RC registration and permit under the Insecticides Act, 1968, with concurrent NDPS Rules and ITC (HS) CWC-overlay conditions administered by DGFT.
Are all imports under HSN 2921 45 32 required to obtain a CIB&RC permit, or only some?
Only substances that figure in the Schedule to the Insecticides Act, 1968 require CIB&RC registration and a permit; importers must verify the Schedule classification of the specific compound before filing the bill of entry, as the obligation is substance-specific rather than CTI-wide.
What additional insurance obligation applies to hazardous substances under this tariff line?
Where imports of specified hazardous substances exceed the quantities prescribed under the Public Liability Insurance Act, 1991, the owner must take out an insurance policy as per S.O. 227(E) dated 24-03-1992 issued by the Ministry of Environment and Forests.
