The United States Transportation Security Administration (TSA) has recently revised its inventory of items barred from both carry-on and checked luggage. This initiative is part of a broader effort to enhance air travel safety and prevent incidents involving hazardous materials that, while commonly found in homes, pose significant risks during flights.
Among the notable restrictions is the ban on wireless styling tools such as flat irons, curling irons, or brushes that contain gas cartridges or are powered by butane in luggage. These devices, favored by influencers and frequent travelers for their convenience, can produce sparks or excessive heat, posing a potential danger on board. Moreover, spare gas cartridges are strictly forbidden in both carry-on and checked baggage, according to TSA regulations.
Understanding Hazardous Materials According to the TSA
Numerous everyday items are classified as hazardous materials or dangerous goods. This category includes lithium batteries, aerosols, flammable liquids, compressed gases, and other products that, when subjected to flight conditions such as vibrations, pressure changes, and temperature variations, can leak, release toxic gases, catch fire, or even explode.
Examples of hazardous materials include:
- Explosives
- Gases
- Flammable liquids and solids
- Oxidizers
- Toxic and infectious substances
- Radioactive materials
- Corrosives
The TSA warns that prohibited items discovered in luggage—whether improperly packed, intentionally concealed, or leaking—may result in civil fines or even criminal charges.
What Can You Pack and What Should You Leave Behind?
The complete list of permissible or restricted items is accessible on the TSA's official website. Key general guidelines include:
- Wireless tools: Banned from checked baggage, but allowed in carry-on luggage only if equipped with a safety cover to prevent accidental activation.
- Corded tools: Permitted in checked luggage.
- Damaged or recalled batteries: Prohibited in both carry-on and checked baggage unless they have been removed or neutralized.
- Personal care products, medications, and medical devices: Allowed in limited quantities and under specific conditions.
Consequences of Carrying Prohibited Items
Travelers attempting to bring forbidden items may face penalties ranging from confiscation of the item to significant fines or arrest. The TSA advises passengers to review regulations in advance and, if uncertain, refrain from including the item in their luggage.
The list of banned articles was last updated in June 2025, and travelers are encouraged to visit the official TSA website before each flight to stay informed about the latest changes.
