United Airlines Carriage & Security Policy

49 CFR § 1540.111 — IATA & Aviation Standards

Carriage of nail polish is governed by TSA security directives under 49 CFR § 1540.111 regarding passenger screening and baggage security. Security rules distinguish sharply between accessible passenger cabin space (where items that could serve as weapons or hazards are prohibited) and cargo hold baggage (where items are safely stowed during flight).

Security Checkpoint Screening Procedure

At the airport screening lane, nail polish will pass through standard X-ray or CT scanning equipment. Keep nail polish neatly arranged in your luggage so officers can get a clear image. If an item appears opaque or clustered with wires or dense materials on the monitor, a secondary manual bag search will be conducted. Cooperate with TSA personnel and allow them to inspect the item without opening sealed packaging yourself.
