A word of counsel

The most frequent error on this tariff line is assuming that CIB&RC applicability is universal rather than Schedule-dependent — if the specific substance is not listed in the Schedule to the Insecticides Act, 1968, the CIB&RC regime does not trigger, but the NDPS and CWC overlays remain independently operative and must be assessed separately. Additionally, the Chapter 29 mandatory qualifiers under CBIC Circular 23/2023-CUS are required at the bill-of-entry stage regardless of which PGA regime applies; omission results in consignment detention pending a revised declaration.

Frequently asked

Does HSN 2921 42 32 require BIS certification?

No, no BIS Quality Control Order covers aniline derivatives under this tariff line. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968 where the substance is Schedule-listed, with concurrent NDPS and CWC policy overlays administered by DGFT.

Are there port restrictions for importing insecticides under this HSN?

Yes. Ports at which insecticides may be imported are restricted; importers must refer to Rule 45 of the Insecticides Rules, 1971 for the notified list of permitted ports before placing a purchase order.

When does the CWC restricted-import condition apply to substances under this CTI?

The CWC condition applies where the specific chemical falls within Category 1A (nitrogen mustards, Appendix II to Schedule I) or Category 1B substances under the ITC (HS) policy; Category 1B imports are permitted only from State Parties to the Chemical Weapons Convention and are subject to those conditions.
