Clear Explanation of What Items Are “OK to Bring” and “Not Allowed” on an Airplane
1. Devices with Non-Removable Lithium-Ion Batteries Are Not Allowed in the Cabin
Devices with built-in rechargeable “lithium-ion batteries,” such as hair irons, dryers, clippers, or massagers, that do not allow the battery to be removed, are not permitted in the airplane cabin.
Devices with removable batteries can be brought onboard if the battery is removed.
• Removed batteries and spare batteries must be under 300Wh
• Only one spare battery is allowed (or two, if each is under 160Wh)
As long as these conditions are met, the batteries themselves may be brought onboard.
If the batteries do not meet these requirements, it’s a good idea to check in advance whether compatible batteries can be purchased at your destination.
2. Liquids Over 500ml Are Not Allowed in the Cabin
Items such as perfumes, toners, nail polish, and nail polish remover must be in containers of 500ml or 550g or less to be allowed in the airplane cabin.
For spray-type hair care products, whether gas-filled aerosol sprays or liquid-filled types, only containers of 500ml or 500g or less may be brought into the cabin.
3. Maximum Allowed Amount of Cosmetics Per Person Is 2L or 2kg
There is a limit on the total amount of cosmetics that each person may carry onboard. The maximum is 2 liters or 2 kilograms. If you exceed this, the items will not be allowed in the cabin and must be disposed of on the spot, so be careful.
This is especially important for women going on long trips by air. If someone you’re traveling with doesn’t carry many cosmetics, you can ask them to share some of your items to help distribute the load and stay within the limit.
4. Small Bladed Items Like Nail Clippers Are Generally Allowed
For domestic flights, small bladed items such as T-shaped razors, facial razors for peach fuzz, and nail clippers with a blade length of 4 cm or less are usually allowed onboard. Scissors may also be allowed if they have blunt tips and poor cutting performance.
Regulations can vary depending on the airline or international flights, so it’s best to check with the official website of the airline you plan to fly with in advance.
◎ Summary
There may have been some items, like nail clippers or cosmetics, that left you wondering how they are classified—but now things should be much clearer. If you’re unsure whether an item can be brought into the airplane cabin, contact the airline or airport in advance. To ensure your favorite personal items aren't confiscated, be careful and have a great trip!
