According to the latest 2026 TSA and international security guidelines, solid lip balm (like a Chapstick tube) does not have to be placed in your clear, quart-sized liquids bag. Solid sticks are considered "solids" and are not subject to the 100ml (3.4 oz) volume restriction. However, if your lip balm is a liquid gloss, a gel, or a cream/paste that comes in a squeeze tube or a pot, it technically falls under the "Liquids, Aerosols, and Gels" rule. To avoid any potential delays at the X-ray machine, many travelers find it easier to simply toss all "smearable" items into their clear plastic bag. While a single small tube of gloss rarely causes an issue if left in a pocket, strict inspectors in hubs like London Heathrow or Frankfurt may insist that anything "non-solid" be bagged. To be perfectly safe, stick to a traditional waxy "solid" balm if you want to keep it in your pocket or a separate vanity kit during the screening process.
