A word of counsel

The most common error on this tariff line is reading the Free-import status under DGFT Notification 44/2025-26 as a complete clearance and overlooking the Chemical Weapons Convention Schedule 1 overlay. P-Alkyl phosphonamidic fluorides are a defining Schedule 1 class; import without prior permission from the National Authority CWC is a Restricted-policy breach attracting seizure and prosecution under the Chemical Weapons Convention Act, 2000, irrespective of the ITC (HS) free-status entry.
