01The rules in detail
Aged hard cheeses (cheddar, parmesan, gouda, manchego) pass security as solids. Soft cheeses are treated as gels in the US and often in Europe — over 100 ml they must be checked. On arrival, the US allows most commercially packaged hard cheeses but restricts some soft/unpasteurised products; Australia and New Zealand are strict on all dairy. Vacuum-sealed and labelled packaging helps at customs.
02Tips
- Vacuum-pack and keep the label for customs.
- Declare it; undeclared food is where fines happen.
03Frequently asked
Can I bring cheese in my carry-on?

Are the rules the same outside the US?
Mostly similar for liquids and batteries, which follow international standards, but sharp objects, tools, lighters and self-defense items vary widely by country. Check the departure airport's rules and the destination's laws.
TSA and other agencies allow officers to refuse any item they judge unsafe, and rules change. This page summarises published guidance as of the verified date; confirm on tsa.gov or your airport's site before packing anything unusual.
