Stay ahead of airport security by knowing the unexpected items the TSA bans—including powders, snacks, gadgets, and more.
Surprising Things You Can’t Bring Through TSA in 2025
Every year, the Transportation Security Administration updates its list of prohibited items to address new security concerns, technological advances, and evolving travel trends. In 2025, the TSA’s rules remain as strict as ever, but many of the items banned this year go far beyond the obvious weapons and massive liquid bottles. The updated restrictions surprise even seasoned travelers, as innocuous items like protein powder, countertop gadgets, snacks, and more end up on the forbidden list. Knowing these rules can save you time, money, and frustration at airport security checkpoints.

Powders & Granular Substances: Restrictions and Red Flags
One of the most surprising carry-on restrictions in 2025 covers powder-like substances. These include everything from protein powder and pancake mix to powdered baby formula and makeup. TSA agents are vigilant because certain powders can mask dangerous chemicals or explosives. Here’s what you need to know:
- If you carry more than 12 ounces (about 350 mL) of any powdery substance in your carry-on, you’ll face extra screening and possible confiscation.
- Protein powder, drink mixes, spice packets, and even bath salts are all frequently flagged.
- To avoid delays, place powders in your checked luggage unless absolutely necessary for your in-flight needs.
- Powders are not banned outright, but quantities above the 12-ounce limit (size of a regular soda can) are highly restricted and subject to inspection.
Pro Tip: Always remove powders from your carry-on and declare them at security checkpoints for the fastest processing.
Lithium Batteries and Electronics: New 2025 Rules
Modern travel relies on portable power—chargers, power banks, laptops, e-cigarettes, and electric razors. However, the TSA’s new battery regulations for 2025 catch many travelers off guard:
- Spare lithium-ion batteries (for gadgets, cameras, and power banks) are forbidden in checked bags. Carry them on the plane, never in your checked luggage.
- Passengers may carry up to two larger spare batteries (101–160 Watt hours) with airline approval in carry-ons only.
- Devices powered by non-standard batteries or without clearly labeled battery details may be confiscated during screening.
- All electronic devices, including e-cigarettes, must travel in your carry-on. Only devices with installed batteries (e.g., phones, laptops) may sometimes be allowed in checked baggage; always verify guidelines first.
Reminder: Place all power banks, charger cases, and spare batteries in your carry-on—never in checked baggage—to avoid confiscation.
Toy Weapons and Lookalikes: Not Child’s Play
Kid-friendly items have drawn increased scrutiny, especially if they resemble weapons. TSA’s updated rules prohibit toys and props that might cause alarm or could be mistaken for real weapons:
- Toy guns, swords, plastic daggers, lightsabers, and foam nunchucks cannot be carried on—even if they’re brightly colored or clearly fake.
- Superhero figurines with miniature weapons or toy projectiles are often confiscated.
- TSA’s priority is to minimize any confusion or potential threats in the cabin, so even novelty items are banned if they could be mistaken for a weapon.
Tip: Leave all toy weapons at home, or pack them in your checked baggage—if airline regulations permit. Avoid last-minute trips to the bin at security!
Camping Gear, Tools, and Outdoor Equipment
Nature lovers and outdoor adventurers should be wary: much camping equipment is tightly restricted by the TSA:
- Tent stakes and metal poles: Considered potential weapons and flagged for removal from carry-ons.
- Camping stoves and fuel canisters: All fuel or flammable liquids are completely banned in both checked and carry-on luggage.
- Certain stove parts or adapters—even if they look harmless—may be seized.
- Sharp-edged utensils (axes, knives, multi-tools) are not permitted in carry-ons. Plastic or folding utensils may be accepted, depending on design.
If you intend to camp or hike upon arrival, ship your gear to your destination or rent locally. Air travel is not the best way to transport your invaluable outdoor equipment.
Personal Care Items and Grooming Gadgets
Surprisingly, even routine grooming devices can be confiscated—especially if powered by unconventional batteries or containing sharp attachments:
- Electric razors, toothbrushes, and hair clippers may be pulled for extra screening if their battery specs are unclear or they use non-standard lithium cells.
- Devices lacking battery watt-hour (Wh) labels might be banned.
- Always carry a backup disposable razor or manual toothbrush, just in case your main device is confiscated.
Keep all small electronics with batteries in your carry-on, and check their specifications before traveling internationally.
DIY Food, Snacks, and Wrapped Items
If you pack your own food for the flight, beware: the TSA frequently flags and inspects certain snacks and food items:
- Homemade snacks wrapped in foil (like sandwiches or granola bars) may be subject to thorough inspection or confiscation.
- Jams, sauces, yogurt, and dips count as liquids/gel and fall under the 3-1-1 rule (max 3.4 ounces each, in a quart-size bag).
- Hard cheeses and dry items (crackers, bread) are generally allowed, but always be prepared for additional screening if scents or textures are suspicious.
- Pies, cakes, and similar foods are allowed but must pass inspection if they contain substantial gels or creams.
If you must carry snacks, aim for prepackaged items in transparent bags to ease the process at security checks.
Other Commonly Confiscated Items in 2025
Alongside the stranger items listed above, the TSA also continues to ban many items you might expect yet overlook in the scramble to pack:
- Firearms and ammunition: Never allowed in carry-ons. Unloaded and locked firearms may be transported in checked baggage, according to airline instructions, with proper declaration.
- Sharp objects: Nearly all are banned in carry-on, including knives, box cutters, razors, ice picks, and large scissors. Blunt-tipped utensils and scissors with blades under four inches are usually fine.
- Self-defense sprays: Pepper spray and mace are not allowed in carry-ons. In checked bags, restrictions apply—only one container (under 4 fl. oz) allowed, with a safety cap.
- Flammables and aerosols: Lighter fluid, gasoline, spray paint, bear spray, and fireworks are universally banned from all luggage. Lighters may be carried on (one per person), but without fuel or in a TSA-compliant case.
- Liquids, gels, and aerosols: Adhere to the 3-1-1 rule for all carry-on items. Larger containers must be checked.
- Unlabeled or unlabeled electronics: Anything with batteries found without safety labeling is subject to removal.
- Medical marijuana and cannabis products: Illegal under federal law, so generally not allowed, even if legal at your destination.
Seasonal Scrutiny and Holiday Travel Tips
TSA’s vigilance ramps up during peak travel seasons, especially during holidays and the summer:
- Fireworks are always banned for July 4th and beyond. Leave them at home every time.
- Don’t wrap gifts before security: TSA officers may need to inspect and unwrap gifts regardless of paper or ribbon, which slows down lines.
- Long lines are likely. Arrive early and keep your items organized to smooth the screening process.
- If in doubt, use TSA’s “What Can I Bring?” digital tool or reach out to @AskTSA on social media for clarification about any questionable items.
