Items Not Allowed in Carry-On: What You Shouldn’t Pack?
Packing your carry-on luggage should be quick and easy — but many travelers unknowingly include items that are restricted or banned at airport security. Whether you’re flying internationally or on a domestic route, airport authorities like the TSA (U.S.), UK Civil Aviation, and EU security follow strict guidelines for what is allowed in the cabin.
Here’s the complete 2025 list of items you must not pack in your hand luggage, along with helpful tips and exceptions to be aware of.
Flammable or Hazardous Items
Airport security agencies across the world strictly prohibit items that are explosive, flammable, or chemically reactive.
Examples include:
- Fireworks, sparklers, or firecrackers
- Gasoline, lighter fluid, or fuels
- Aerosol spray paints
- Camping gas canisters or portable stoves with fuel
- Bleach, corrosive cleaners, or paint thinner
These items pose a serious safety risk and must never be packed in carry-on or checked baggage.
Sharp Objects & Weapons
You may not carry sharp items that could be used as weapons or cause injury to others. These are almost always confiscated at security checkpoints.
Not allowed in carry-on:
- Scissors with blades over 6 cm
- Pocket knives or Swiss army knives
- Razor blades not in cartridges
- Box cutters or utility knives
- Screwdrivers, hammers, or any hand tools
- Martial arts equipment
- Toy or replica guns (including water pistols)
If you need to travel with these items, pack them in your checked luggage instead.
Liquids Over 100ml
The 100ml liquid rule continues in 2025, and it applies to all liquid, gel, and aerosol items.
Common restricted items include:
- Full-size shampoo, conditioner, or lotion bottles
- Perfume bottles over 100ml
- Liquid makeup, like foundation or lip gloss
- Mouthwash, hand sanitizer, or sunscreen
- Food sauces, soups, or beverages
All liquids must be under 100ml each and fit within a single 1-litre clear plastic zip-lock bag. Only one bag is allowed per passenger.

Power Banks & Batteries
While allowed in carry-on bags, power banks and spare lithium batteries are strictly not permitted in checked baggage. They must meet airline capacity limits.
Carry-on only:
- Power banks up to 100Wh (most airlines)
- Spare lithium-ion batteries for laptops, cameras, or drones
- E-cigarettes and vapes (must be removed from pockets during flight)
If your power bank exceeds 100Wh, you may need airline approval. Always check before flying.

Items With Blade or Metal Risk
Even small items that might seem harmless can be banned if they contain blades or hard metal edges.
Not allowed:
- Nail files with pointed metal ends
- Metal combs or grooming scissors
- Metal knitting needles (some countries ban them)
- Ice skates, corkscrews, or metal cutlery
Plastic alternatives are usually allowed, but you should check with your airline in advance if unsure.
Medical Items & Exceptions
Some items that are generally banned may be allowed if they are for medical or essential personal care use.
Allowed with declaration:
- Insulin pens and needles
- Prescribed medications in liquid form
- Cooling gel packs for medical use
- Baby formula or breast milk (in reasonable quantities)
Always carry a doctor’s note or prescription, and inform the security staff during screening.
Everyday Items That Are Surprisingly Banned
These items often catch travelers off guard because they seem harmless but are not allowed.
Examples:
- Snow globes (even small ones exceed the 100ml rule.
- Disposable lighters (one per person may be allowed in some countries)
- Tools or hardware over 6 inches
- Sporting goods like baseball bats or pool cues
- Drones (batteries allowed in cabin, but some airlines restrict the device itself)
FAQs – Items Not Allowed in Carry-On
Can I bring a razor in my carry-on?
Yes, if it’s a disposable razor or cartridge-style razor. Straight razors or loose blades are not permitted.
Is deodorant allowed in hand luggage?
Stick deodorants are allowed. Spray or roll-on types count as liquids and must be under 100ml.
Can I take food in my cabin bag?
Solid food is usually allowed. Liquids, sauces, or spreads (like yogurt or peanut butter) must follow the 100ml rule.
What if I forget and pack a restricted item?
Airport security will remove the item. If you want to keep it, you’ll need to exit security and check it in (if time allows).
