Compliance steps

1
Where diphenylamine or its derivatives fall within 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. Route the consignment only through places at which insecticides may be imported under Rule 45 of the Insecticides Rules, 1971.
Insecticides Act, 1968 · Rule 45 of the Insecticides Rules, 1971 · ITC (HS) policy, Chapter 29
2
Where the substance is an NDPS-scheduled compound, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 for medical and scientific purposes, or comply with Appendix I to the ITC (HS) Schedule for all other imports. Verify the CWC-restricted schedule status for any nitrogen mustard or N,N-dialkyl aminoethyl-2-chloride derivatives before placing the purchase order.

A word of counsel

The most common error on this tariff line is assuming that because diphenylamine is an industrial chemical, none of the CIB&RC or NDPS overlays are triggered. The Schedule to the Insecticides Act, 1968 is product-specific and fact-dependent: an importer must verify whether the particular derivative or formulation appearing in the shipment is listed before the bill of entry is filed. Arriving without a CIB&RC permit at a non-notified port is treated as an Insecticides Rules contravention independent of any DGFT policy clearance already obtained.

Frequently asked

Does HSN 2921 44 10 require BIS certification?

No, diphenylamine and its derivatives are not subject to any BIS Quality Control Order. Import is governed primarily by Central Insecticides Board and Registration Committee registration and permit requirements under the Insecticides Act, 1968, with NDPS, CWC, and DGFT ITC (HS) policy overlays applying depending on the specific compound.

Are all diphenylamine imports subject to CIB&RC registration, or only certain formulations?

Only those items that figure in the Schedule to the Insecticides Act, 1968 require CIB&RC registration and a permit; the Schedule must be checked against the specific derivative or formulation being imported, and Rule 45 of the Insecticides Rules, 1971 further restricts the ports through which such insecticides may be imported.

What happens if the consignment contains a CWC-scheduled precursor derivative?

Nitrogen mustards classified under Appendix II to Schedule I (Category IA) are Restricted and require permission from the national authority; derivatives under Category IB may only be imported from State Parties to the Chemical Weapons Convention subject to the conditions set out in the ITC (HS) policy, and non-compliant consignments are liable to seizure and confiscation.
