TSA Has BANNED 7 Surprising Items in 2025 — Avoid This Airport Mistake Before Your Flight
Did you know that starting in 2025, airport security regulations in the United States could prevent you from bringing along items like protein shakes, high-tech smart suitcases, or even seemingly harmless “empty” water bottles in your carry-on?
The TSA’s newly proposed rules have come as a surprise to frequent flyers, not for targeting obvious threats like weapons or liquids, but for restricting everyday travel essentials that many travelers pack routinely and without a second thought.
7. Tech Cases with Hidden Compartments
Here’s the newest — and possibly strangest — addition to TSA’s 2025 banned list.Tech organizers, RFID wallets, and thick gadget sleevesare now being flagged at record rates.
The reason? Hidden compartments. Over the past year, TSA scanners detected a surge inconcealment cases— sleeves with double linings, secret zippers, and magnetic closures. Some were harmless travel accessories. But others were used tohide SD cards, tracking devices, and even narcotics.
The new scanners at airports likeDallas–Fort WorthandLAXare programmed to automatically flag any bag or tech case withmultiple layers or irregular density. Even if you’re just carrying charging cables or memory cards, your case might be pulled for hand inspection.
TSA now advises travelers to usetransparent or single-layer organizers. Keep things simple, visible, and easy to scan because even something as innocent as your phone case can now look “suspicious” under the machine.
And here’s the twist: many modern accessories — like smart wallets and RFID-protected sleeves — are being flagged just because theyblock X-rays. So, the very feature designed to protect your privacy might now cause a full-blown bag search.
6. DIY Snacks
Homemade snacks were once the traveler’s best hack. But in 2025, TSA officially changed the game. Anythingscoopable, squeezable, or pourable— fromovernight oats to peanut butter sandwiches— now counts as aliquid or gel.
That means your yogurt parfait, chia pudding, or hummus dip could beconfiscatedif it exceeds the3.4 oz rule.
The logic? Consistency again. TSA’s tests showed that soft foods canmask gel-like substances or chemicals.
This change has caused chaos at security lines — especially among parents and health-conscious travelers.
So, what’s safe now? Stick tosolid snacks— granola bars, crackers, dried fruits, or sealed baby food containers — and keep them under the limit. Because yes, even a spoon of peanut butter now needs to “pass the test.”
5. Portable Blenders & Massagers
In 2025,motorized gadgetsare getting flagged like never before. Frommini blenderstomassage guns, evenelectric toothbrushes— anything with abuilt-in motor or lithium batteryis now considered a potentialimprovised device.
This rule came after multiple cases where disguised motors were used to smuggle restricted components.
The most affected travelers? Fitness enthusiasts and wellness vloggers who travel with self-care gear. TSA reports a40% increasein gadget-related screenings this year.
If you’re carrying a portable blender, be ready: they may ask you topower it onto prove it’s safe. The same goes for massage guns or facial devices.
To avoid trouble, keep such itemscharged, visible, and accessible. Avoid traveling with niche or unfamiliar brands — they’re more likely to be pulled for extra screening.
4. Creams, Balms, and Solid Lotions
This one’s catching travelers completely off guard. TSA now classifies products byhow they behave, not how they look.
If itsmears, melts, or spreads, it’s treated as aliquid or gel, even if it looks solid. That means things likedeodorant sticks, lip balms, sunscreen sticks, and ointment barsall fall under the3.4 oz (100 ml)limit.
The logic comes from a new“consistency-based” classificationthat went live in January 2025. TSA officers atChicago O’HareandAtlanta Hartsfield-Jacksonare using it heavily.
It’s not about confusing passengers — it’s about closing loopholes. Some banned gels were being disguised as solid sticks, so TSA shut that door completely.
Now, even solid deodorants might get tossed if they’re oversized or unsealed.
The smart move? Treat everything semi-solid as liquid. Keep them in a clear quart-size bag, labeled, and under 3.4 ounces. It’s better than watching your $30 face balm end up in the bin.
3. Reusable Water Bottles
Yes, even that stylishstainless-steel bottlecan now get you stopped at the gate. TSA’s latest rule targetsopaque reusable bottles, even if they appear empty.
The reason? Smugglers have used them tohide alcohol, CBD oil, and powdered drugs. Some modern bottles even come withhidden compartments— and X-ray machines can’t always see through the double-walled metal.
As of 2025, major airports likeMiami InternationalandSeattle-Tacomahave added extraswab testingfor all metal and insulated bottles.
Even if your bottle’s bone dry, officers may ask you to open it, prove it’s empty, or send it for further inspection. The new rule feels extreme — but TSA argues it’s about visibility and safety.
So, to save time, keep your bottleopen and clearly emptywhen passing through screening. And if it’s one of those double-insulated types? You might want to leave it at home.
2. Smart Suitcases
Remember whensmart luggagebecame the next big travel trend? Well, TSA’s 2025 crackdown just hit them again — harder than ever.
Any bag with anon-removable lithium batteryis nowbannedfrom both check-in and cabin baggage. Airlines likeDelta, United, and Americanhave updated their terms to match the TSA’s rule.
Why? Lithium-ion batteries canignite or explodeunder pressure. After several 2024 incidents where smart bags caused smoke alarms during loading, TSA decided enough was enough.
Now, even if you’ve never used your bag’s charging port or GPS tracker, the simple fact that thebattery isn’t detachablemakes it unsafe.
If you own a smart suitcase, double-check the design. If the battery can’t be easily removed, your bag might get confiscated on the spot. The safest bet? Remove the battery before heading to the airport — and carry it separately in your hand luggage.
1. Powders Over 12 Ounces
Here’s where the confusion starts. Powders — things like protein mix, baby formula, fiber-rich supplements, or powdered fruit drinks — are now understrict inspection. TSA’s 2025 policy states that anything over12ounces (350 ml)must undergochemical swabbing, even if sealed and labeled.
Why? Because powders can disguiseexplosives or narcotics, and smugglers have been caught using this trick at major U.S. airports likeJFK and LAX. TSA officers now treat large powder containers aspotential hazards, not casual gym gear.
Even fitness enthusiasts and parents have been caught off guard — baby formula tins and collagen tubs are among the top flagged items this year.
If you’re traveling soon, make sure your powder containers areunder 12 ozand clearly labeled, or just pack them in checked luggage, because one innocent scoop could now mean a full bag search.
Why 2025 Airport Security Feels Different?
These new restrictions might sound excessive, but they’re the result ofreal incidents and evolving threats.
In 2024 alone, TSA confiscatedover 6,000 prohibited itemsthat weren’t weapons — but everyday things cleverly disguised. Powdered supplements turned out to be narcotics. Smart suitcases triggered smoke alarms. “Solid” deodorants were actually gels in disguise.
So, in 2025, TSA changed its focus fromwhat something istowhat it could be used for.That’s why categories like“powder restriction,” “consistency-based classification,”and“hidden compartment detection”now dominate their reports.
These new rules are part of TSA’s “Smart Safety 2.0” initiative — a system built on AI-assisted scanning and predictive flagging. The machines no longer just detect shapes; they detectbehavioral patternsin materials.
But here’s the issue: in trying to stop clever smugglers,regular travelersare paying the price. People are missing flights over protein powders, getting their USD200 smart bags confiscated, and watching their skincare tossed out for being too “spreadable.”
So, the 2025 TSA experience isn’t just about what you pack — it’s abouthow it looks under an algorithm’s eye.
What You Can Do
Before flying, alwayscheck the latest TSA updates— they now post monthly rule changes on their site and in theMyTSA app.
Here’s what seasoned travelers are doing differently this year:
- Packing onlyclear-labeled powders under 12 oz
- Removingsmart bag batteriesbefore arriving at check-in
- Keepingreusable bottles open and visibly empty
- Treatingall creams and balms as liquids
- Avoidingmotorized or rechargeable gadgetsunless essential
- Packingsolid snacks only
- Usingsimple, see-through organizersfor tech gear
Simplify your packing — it’s the only real shortcut through modern airport chaos.
So yeah — who would’ve thought your protein mix or sunscreen stick could land you in a full security check? TSA’s new rules in 2025 might feel extreme, but they’re not going anywhere soon.
The smart move? Travel lighter, label smarter, and never assume something “harmless” won’t raise eyebrows.There’s a lot more coming that airlineswon’twarn you about.
