Where N,N-diethylaniline is covered by the Schedule to the Insecticides Act, 1968, obtain registration and an import permit from the Secretariat of the Central Insecticides Board and Registration Committee before shipment. Note that import is restricted to ports specified under Rule 45 of the Insecticides Rules, 1971; consignments routed through any other port are liable to seizure.

If the substance is imported for medical or scientific purposes under the NDPS framework, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 from the Central Bureau of Narcotics (cbn.nic.in) prior to filing the bill of entry. Imports outside this category are governed by Appendix I to the ITC (HS) Schedule.

A word of counsel

The most common error on this tariff line is failing to recognise that CIB&RC, NDPS, and CWC controls can apply simultaneously to a single consignment — each triggered by the specific end-use or composition of the substance, not by the HSN alone. An importer who secures only the NDPS import certificate but omits the CIB&RC permit where the substance is scheduled under the Insecticides Act, 1968, will face consignment detention at the restricted port of import. The Chapter 29 additional-qualifier requirement under CBIC Circular 23/2023-Cus is a separate customs-declaration obligation that must be met irrespective of which PGA clearance applies.

Frequently asked

Does HSN 2921 42 22 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, with concurrent NDPS and CWC-based ITC (HS) restricted-import controls administered by DGFT.

Are there port restrictions for importing N,N-diethylaniline?

Yes. Where the substance falls within the Schedule to the Insecticides Act, 1968, import is restricted to the ports specified under Rule 45 of the Insecticides Rules, 1971; routing through any unspecified port renders the consignment liable to detention and seizure.

When does the CWC restricted-import condition apply to this tariff line?

The CWC restriction applies where the specific chemical identity of the substance matches a Category 1A or Category 1B chemical listed in Appendix II to Schedule I of the ITC (HS) policy; import is then permitted only from State Parties to the Chemical Weapons Convention and subject to national authority permission.
