Model Paint, Thinner & Air Travel: What to Check
A hobby shop can legally sell an item that your airline will not accept in passenger baggage. Check transport first.

Treat liquids, aerosols and solvents as a separate purchase decision
IATA's current passenger dangerous-goods guidance explains that dangerous goods are generally restricted from passenger baggage unless a specific exception applies. Paints, thinners, cements and aerosols can fall into regulated categories depending on their formulation and packaging.
Do not use the 100 ml security rule as a safety guarantee
Carry-on liquid screening limits and dangerous-goods rules are different systems. A container small enough for security screening can still be prohibited because of flammability or another hazard classification.
Check the exact product, not just “acrylic” or “lacquer”
Record the manufacturer, product name, volume and safety classification. Then ask your airline whether it is accepted in cabin baggage, checked baggage or neither. Do this before buying a set of paints or thinner solely because it is cheaper in Japan.
Blades and sharp tools are another rule set
IATA passenger baggage guidance notes that sharp cutting implements are not permitted in carry-on baggage and generally need to be handled as checked baggage subject to local and airline rules. Hobby knives and spare blades therefore need their own check.
Safer shopping priorities for a flight home
When baggage uncertainty is high, prioritize dry tools and supplies whose transport rules you have confirmed: sanding items, files, tweezers or compatible parts. Use our model-tool guide and leave regulated liquids or blades behind when the rule is unclear.
Make the store decision binary when transport is unclear
If the airline or security authority cannot clearly approve the exact product, treat that uncertainty as a reason not to buy it for the flight home. A cheaper bottle of thinner or aerosol is not a bargain if it must be surrendered at the airport. Save the product name and safety information first; buy only after the transport rule is resolved.
