Can you take a soldering iron on a plane? Rules by country

Soldering irons on flights in and from Japan

The rule for soldering irons comes from the Civil Aviation Bureau's list of restricted items and is the same on domestic and international flights.

Soldering irons and glue guns: carry-on and checked baggage in Japan
Where	Allowed?	What applies
In the cabin	Yes, within limits	Plug-in type, including ones powered from a power bank: yes. Battery type: only if the battery can be separated from the heat source. Gas type: no. Whatever the type, one with a sharply pointed tip cannot be carried on.
In checked baggage	Conditions	Plug-in type: yes. Battery type: only if the battery can be separated from the heat source, and a removed lithium-ion battery goes in the cabin. Gas type: no.

Soldering irons and glue guns: tip, power source and gas

Japan's list puts soldering irons and glue guns in one row and sorts them by how they are powered. The tip is judged separately.

Glue guns share the row: The row in Japan's list is headed soldering irons and glue guns, so a hot glue gun gets the same answers. The row is split by power source into plug-in, lithium-ion battery, other battery and gas types, and the plug-in type is the only one marked as non-dangerous goods.
The pointed-tip remark sits under every type: The list repeats one remark under the plug-in type, the lithium-ion type and the other-battery type: an iron whose tip is sharply pointed may not be carried on. The remark concerns the cabin, so the same iron can still travel in checked baggage when its power type is one the list accepts there.
What separable means for battery irons: For battery types the list gives examples of separation: taking the battery out of the body, or being able to cut the electrical circuit between battery and heat source. A lithium-ion battery must be 160Wh or less. Once removed it needs short-circuit protection and may only be carried on. Other kinds of removed battery need the protection too but are not barred from the hold.
Gas irons: refused in Japan, conditional in Australia: Japan's list refuses gas soldering irons filled with hydrocarbon gas in cabin and hold. It treats gas hair irons differently: Narita's FAQ confirms those may travel when the safety cover is fixed over the heat source. Australia's CASA takes a gas or liquid-fuel iron only if it is new and has never been filled, or is empty and completely cleaned, with airline approval.

Soldering irons: the rule country by country

The carry-on answer for soldering irons is the same in the other place we checked. The limits themselves are not identical, so read the row for the country you fly from.

Each row comes from that authority's own page. Airlines can be stricter, and the screening officer has the final say.

If security in Japan will not let soldering irons through

What to do: Move soldering irons to the bag you check in before you reach security, within the checked-baggage limits above. Narita Airport states that anything given up at the checkpoint is discarded and cannot be returned.

Frequently asked questions

Can you take a soldering iron on a plane?

On flights in and from Japan: Plug-in type, including ones powered from a power bank: yes. Battery type: only if the battery can be separated from the heat source. Gas type: no. Whatever the type, one with a sharply pointed tip cannot be carried on. In checked baggage: Plug-in type: yes. Battery type: only if the battery can be separated from the heat source, and a removed lithium-ion battery goes in the cabin. Gas type: no.

Can you take a hot glue gun on a plane?

Yes, on the same terms as a soldering iron, because Japan's list puts glue guns in the same row. A plug-in glue gun is non-dangerous goods and may go in the cabin or the hold. A battery model is accepted only when the battery can be separated from the heat source, and a gas model is refused in both.

Can you take a USB soldering iron in carry-on?

Yes, if it has no battery of its own and its tip is not sharply pointed. Japan's list counts irons powered from a power bank or a similar source as the plug-in type, which is non-dangerous goods and accepted in cabin and hold. An iron with a lithium-ion battery inside is accepted only when the battery can be separated from the heat source. The power bank that feeds it stays in the cabin, limited to 2 per person.

Can you put a soldering iron in checked luggage?

Plug-in type: yes. Battery type: only if the battery can be separated from the heat source, and a removed lithium-ion battery goes in the cabin. Gas type: no.

What is the rule for soldering irons on flights from Australia?

Australia: Battery-powered soldering irons: carry-on or checked with airline approval, the heat-producing component and the battery packed separately. Gas or flammable-liquid types only if new and never fuelled, or empty and completely cleaned.
