You can generally take a curling iron in your carry-on bag, but the specific rules depend on the device type. The Transportation Security Administration (TSA) has different regulations for corded models compared to those powered by gas or batteries. Understanding these distinctions is important for a smooth experience at the security checkpoint. The primary concern for all hair styling tools is preventing accidental activation or fire hazards during the flight.
Rules for Standard Corded Curling Irons
Electric curling irons that plug into a wall outlet are considered standard electronic devices and face no special restrictions for air travel. These corded models are permitted in both carry-on and checked baggage. The TSA views them similarly to other small appliances, such as hair dryers, which do not pose a combustion risk. The lack of a battery or fuel source means these devices are not subject to strict hazardous materials regulations.
Restrictions on Cordless and Gas-Powered Models
Cordless curling irons, whether powered by lithium-ion batteries or butane gas cartridges, are subject to stricter rules due to the potential for fire or explosion. The Federal Aviation Administration (FAA) and TSA prohibit these devices from being placed in checked luggage. This restriction is in place because a thermal runaway event from a lithium battery or a gas leak in the cargo hold could be difficult to detect and manage.
Butane and Gas-Fueled Models
Cordless curling irons that contain a gas cartridge, typically butane, are allowed only in carry-on bags. The device must have a safety cover securely fitted over the heating element to prevent accidental activation. The TSA limits travelers to one butane-fueled curling iron per person, and the gas cartridge must be installed in the device. Spare gas refills or cartridges are strictly prohibited in both carry-on and checked baggage.
Battery-Powered Models
Cordless curling irons powered by lithium-ion or lithium metal batteries must be transported exclusively in carry-on luggage. Lithium batteries are required to be in the cabin so that flight crew can monitor and respond quickly if the battery overheats. To prevent a short circuit or accidental heating, the device must be protected from accidental activation. Some manufacturers design these tools with a removable battery or a safety feature that puts the device into a travel or “airplane mode.”
Essential Packing and Safety Tips
Regardless of the type of curling iron you travel with, proper packing is necessary to protect both the device and your belongings. If you use your curling iron shortly before packing, allow it to cool completely before placing it in your bag. Packing a hot tool can melt synthetic fabrics or damage other items.
Using a heat-resistant pouch or mat provides an immediate layer of insulation. For corded models, wrapping the cord neatly and securing it with a strap prevents tangling and damage to the cord’s connection point. This helps maintain the integrity of the internal wiring.
For international travel, you must check the voltage requirements of your curling iron against the destination country’s electrical system. Most US appliances operate on 110-120V, while many countries use 220-240V. Plugging a single-voltage US iron into a higher-voltage foreign outlet can destroy the device or cause a fire. If your iron is not dual-voltage, you will need a voltage converter, not just a simple plug adapter, to safely use the appliance abroad.
