What Is Not Allowed in Checked Baggage? TSA and FAA Rules Explained

 

Packing for a flight should be simple, but knowing what is allowed in checked baggage can sometimes be confusing. Many travelers assume that if an item cannot go through airport security in a carry-on bag, it can automatically be placed in checked luggage. Unfortunately, that is not always true.

Some everyday items, including portable phone chargers, spare lithium batteries, certain hair-styling tools, and aerosol products, are prohibited from checked baggage. Other items are prohibited from airplanes entirely.

Whether you're preparing for a family vacation, business trip, international flight, or cruise vacation, understanding the rules before leaving home can help prevent delays, confiscated items, and unexpected problems at the airport.

What Is Not Allowed in Checked Baggage?

The short answer: According to TSA and FAA guidance, items generally prohibited in checked baggage include:

• Spare lithium-ion and lithium-metal batteries

• Portable power banks and external phone chargers

• Electronic cigarettes and vaping devices

• Fireworks, sparklers, explosives, and flares

• Gasoline, propane, butane fuel, and other flammable fuels

• Spray paint and many flammable aerosol products

• Torch lighters and strike-anywhere matches

• Cordless butane-powered curling irons

• Loaded firearms

• Certain corrosive chemicals, poisons, and compressed gases

• Alcoholic beverages containing more than 70% alcohol by volume (140 proof)

Some of these items may travel in carry-on baggage instead, while others cannot be transported on passenger aircraft at all.

Important: These rules generally apply to flights departing from or operating within the United States. Airlines and international destinations may impose additional restrictions.

This chart is a general guide, not an exhaustive list. Always verify unusual items with the airline and the appropriate federal agency.

1. Lithium Batteries, Power Banks, and Portable Chargers

One of the most common packing mistakes involves lithium batteries.

Spare lithium batteries and power banks are not allowed in checked baggage. This includes portable phone chargers, loose rechargeable lithium batteries, and many battery charging cases.

Lithium batteries can overheat or catch fire if damaged or short-circuited. Keeping spare batteries in the passenger cabin allows flight crews to respond more quickly to a problem.

Can I pack a laptop or tablet in checked luggage?

Generally, yes. Laptops, tablets, cameras, and other electronic devices containing installed lithium batteries may be permitted in checked baggage if they meet battery-size requirements.

However, these devices must be completely turned off, not simply placed in sleep mode, and protected from accidental activation or damage.

We recommend keeping valuable electronics in your carry-on bag whenever possible.

What about battery size?

Most ordinary lithium-ion batteries up to 100 watt-hours (Wh) are permitted under standard passenger rules. Certain batteries between 101 and 160 Wh require airline approval, while larger lithium-ion batteries generally cannot travel on passenger aircraft.

Spare batteries must remain in the cabin regardless of whether they otherwise meet the permitted size limits.

2. E-Cigarettes and Vaping Devices

Electronic cigarettes, vape pens, and similar battery-powered smoking devices are prohibited in checked baggage.

These items must travel in carry-on baggage or on your person and must be protected against accidental activation.

Using or charging vaping devices aboard the aircraft is prohibited.

Travel tip: If your carry-on bag is unexpectedly checked at the gate, remove your vaping devices, spare lithium batteries, and power banks before handing over the bag.

3. Fireworks, Explosives, and Flammable Materials

Fireworks and explosives are prohibited in both checked and carry-on baggage.

Examples include:

• Firecrackers, sparklers, and bottle rockets

• Signal flares and gunpowder

• Gasoline and lighter fluid

• Propane and butane fuel canisters

• Many flammable paints, adhesives, and solvents

Even small fireworks or fuel containers can create serious safety hazards aboard an aircraft.

Camping equipment that previously contained fuel may also be restricted unless properly cleaned and completely free of fuel and vapors.

4. Aerosols, Hairspray, Deodorant, and Toiletries

Not every aerosol product is prohibited from checked baggage.

Common personal-care items, such as hairspray, shaving cream, sunscreen, and aerosol deodorant, are generally permitted in checked luggage, subject to FAA limits.

For regulated medicinal and toiletry products:

• Each container must not exceed 500 milliliters (17 fluid ounces) or 0.5 kilograms (18 ounces).

• The combined total per passenger must not exceed 2 liters (68 fluid ounces) or 2 kilograms (70 ounces).

• Aerosol nozzles must be protected against accidental release.

However, flammable non-toiletry aerosols, such as spray paint, spray starch, and many lubricating sprays, are prohibited.

Travel tip: The TSA 3-1-1 liquid rule generally applies to carry-on baggage, not checked baggage. However, larger containers in checked luggage must still comply with hazardous-material regulations.

5. Curling Irons, Hair Straighteners, and Styling Tools

Travelers should pay particular attention to cordless hair-styling tools.

Butane-powered cordless curling irons are not permitted in checked baggage. Under FAA guidance, one may be carried in carry-on baggage if the heating element has a securely fitted safety cover and the device is protected against accidental activation.

Spare gas refill cartridges are prohibited.

Regular electric curling irons and hair straighteners that plug into a wall outlet are generally permitted in both checked and carry-on baggage.

Battery-powered cordless styling tools may be subject to separate lithium-battery and heat-producing-device requirements. Check the exact device before packing.

6. Firearms, Ammunition, and Self-Defense Sprays

Firearms and ammunition have special transportation requirements.

Unloaded firearms may be transported in checked baggage when properly secured in a locked, hard-sided case and declared to the airline at check-in.

Loaded firearms are prohibited.

Small-arms ammunition may be transported in checked baggage if securely packaged and compliant with airline and federal requirements.

Certain self-defense sprays may be permitted in checked baggage under limited U.S. rules, but airlines and international destinations frequently impose stricter restrictions.

Travelers should never assume that an item permitted on a domestic flight will be allowed on an international itinerary.

7. Alcohol and Other Flammable Liquids

Alcoholic beverages are subject to restrictions based on alcohol content.

Beverages containing more than 70% alcohol by volume (more than 140 proof) are prohibited in checked and carry-on baggage.

Beverages containing more than 24% but not more than 70% alcohol by volume are generally limited to 5 liters per passenger in unopened retail packaging.

Beverages containing 24% alcohol or less are not subject to those particular FAA hazardous-material quantity limits, although baggage weight, customs, and airline restrictions may still apply.

8. Compressed Gases, Chemicals, and Hazardous Materials

Many hazardous household and industrial products cannot travel in checked baggage.

Examples include:

• Propane and butane cylinders

• Certain pressurized gas cartridges

• Drain cleaners and corrosive chemicals

• Strong oxidizers and pool chemicals

• Many pesticides and toxic substances

• Certain wet-cell batteries

• Infectious substances and radioactive materials

Some specialized medical devices, mobility aids, life-saving equipment, and other products have exceptions or require advance airline approval.

When traveling with unusual equipment, contact your airline before arriving at the airport.

What Items Are Allowed in Checked Baggage but Not Carry-On?

An important distinction is that some items prohibited at TSA security checkpoints are allowed in checked baggage.

Examples generally include kitchen knives, many scissors and sharp tools, larger containers of ordinary shampoo and lotion, and properly declared unloaded firearms.

Sharp objects should be securely wrapped or sheathed to prevent injury to baggage handlers and inspectors.

Remember that being allowed in checked baggage does not necessarily mean an item is permitted by every airline or in every destination country.

Frequently Asked Questions About Checked Baggage

A prohibited item may be removed, and your baggage may be subject to additional inspection. Depending on the item and circumstances, you could experience delays, confiscation, civil penalties, or law-enforcement involvement.
