25 Items to Keep Out of Your Checked Baggage to Pass TSA Inspection

Packing for air travel requires careful consideration, especially when it comes to items in your checked luggage. The Transportation Security Administration (TSA) has strict rules about what can be transported beneath the plane to ensure passenger safety.

From potential hazards to simple conveniences, understanding these regulations can prevent last-minute disruptions at the airport.

Let’s highlight the most common items the TSA prefers not to find in your checked bags, helping you travel smarter and more securely.

Lithium Batteries

Lithium batteries are a major concern for the TSA when placed in checked luggage due to their potential fire risk. They are known to overheat and can cause fires in the cargo area. Passengers are advised to carry these batteries in their carry-on bags instead.

Firearms

Firearms must be declared and transported in specific, TSA-approved cases when flying. They cannot simply be tossed into your checked luggage without proper procedures and permissions. Undeclared firearms in checked luggage can lead to criminal charges and hefty fines.

E-cigarettes and Vaping Devices

The TSA prohibits e-cigarettes and vaping devices in checked luggage because they carry a fire hazard similar to lithium batteries. These items must be packed in your carry-on baggage. Failing to comply can result in delays and potential confiscation.

Flammable Liquids

Flammable liquids, including gasoline, paint, and lighter fluid, are not allowed in checked or carry-on luggage due to their combustible nature. The risk of explosion and fire is too great to permit these substances on an aircraft. Always check the TSA’s list of prohibited items before packing.

Explosive Materials

Explosives, including fireworks, flares, and blasting caps, are strictly forbidden in both checked and carry-on luggage. Such materials pose a significant safety threat aboard an aircraft. Violators may face severe penalties under federal law.

Self-Heating Meals

Self-heating meals and any other items that include a heat-generating chemical reaction are banned from checked luggage. These can generate enough heat to cause a fire hazard. Always opt for non-self-heating meal options when traveling.

Hoverboards

Hoverboards are typically powered by lithium batteries, which, as mentioned, pose a fire risk and are not allowed in checked luggage. If you must travel with a hoverboard, check with the airline for their specific policy regarding these items. They usually require to be carried on and may need to be inspected.

Sharp Objects

Sharp objects such as knives, swords, and large scissors should be securely wrapped and, if permissible, packed in checked luggage. However, they must be declared and packed properly to avoid injury to baggage handlers and inspectors. Incorrect packing can lead to confiscation or fines.

Bleach and Toxic Chemicals

Chemicals such as bleach and chlorine are hazardous and banned from both checked and carry-on luggage. These substances can cause damage to property and pose health risks to passengers and crew. Packing such items can lead to delays and possible legal action.

Wet Cell Batteries

Except for those used in wheelchairs or similar mobility aids, wet cell batteries are generally prohibited in checked baggage because of spillage risks. If you need to travel with such a battery, prior arrangements with the airline are necessary. They must be properly packed according to airline regulations.

Pepper Spray

While a small can of pepper spray may be allowed in checked luggage with restrictions, generally, it’s advised against due to the potential for accidental discharge. Always check the size and concentration limits and ensure it’s properly sealed. Mishandling of such items can cause serious security concerns.

Compressed Gas Cylinders

Compressed gas cylinders, including those for diving or medical use, are usually restricted or entirely prohibited in checked luggage. These can explode under pressure changes during a flight. Necessary medical equipment should be cleared with the airline ahead of time.

Magic 8 Balls

Oddly enough, Magic 8 Balls are not allowed in checked luggage due to the liquid inside them. The liquid is classified as hazardous, posing a risk during the pressure changes in flight. Carry them on, or leave them at home.

Alcohol Over 140 Proof

Alcoholic beverages over 140 proof are considered hazardous due to their high flammability. While lower-proof alcohol is permissible in limited quantities, anything above this threshold is banned from both carry-on and checked bags. Check your beverage’s proof level before packing.

Bear Spray

Bear spray, a common item for hikers and campers, must adhere to strict regulations if transported. Due to its high-capacity canister and potent formula, it is generally not allowed in checked baggage. For safety reasons, purchase it at your destination instead.

Paint

Cans of paint are prohibited in checked luggage because they are considered flammable liquids. If traveling for a painting project, consider shipping your materials ahead of time or buying them upon arrival. This ensures compliance with airline regulations and avoids complications during travel.

Ice Packs with Gel

While frozen solid ice packs are allowed, gel ice packs may pose a problem unless they are frozen solid at the time of screening. If thawed, they could be subjected to the same restrictions as liquids, gels, and aerosols. Plan accordingly to keep medications and perishables cool.

Medical Marijuana

Despite legality in many states, federal law prohibits flying with marijuana, including medical marijuana. Even in checked luggage, the presence of marijuana can lead to legal complications due to its status under federal law. Always research laws and airline policies before traveling with prescribed cannabis.

Large Quantities of Powder

Following specific incidents and for general safety, the TSA advises against traveling with large quantities of non-prescribed powders (more than 12 ounces) in checked luggage. These can raise suspicions and may require additional screening. Pack them in your carry-on for easier inspection.

Ski Wax

Ski wax is typically not allowed in checked luggage due to its chemical composition and potential to act as a fire accelerant. If you’re heading to the slopes, consider buying your wax locally or shipping it ahead to your destination.

Strong Magnets

Strong magnets can interfere with an airplane’s navigational equipment and are banned from checked luggage. If you’re transporting magnets, ensure they are adequately shielded and meet specific guidelines set by the TSA.

Cast Iron Cookware

Due to its heavy weight, cast iron cookware can pose a risk to baggage handlers and is frowned upon in checked luggage. It’s better to ship such items or check with your airline for their specific policies regarding heavy objects.

Live Coral

Live coral, often transported for aquariums, is subject to various regulations and is not allowed in checked luggage due to conservation concerns and the potential for damage. Transporting live coral requires special permits and packaging, often coordinated through specialized cargo services.
