🥜 Nuts

Nothing — nuts are a dry solid food with no restrictions at security anywhere in the world. Screeners will not flag them regardless of quantity. You can carry as many bags of nuts as you like in both carry-on and checked baggage.

Nuts are a plant product, and some countries with strict biosecurity — particularly Australia and New Zealand — require you to declare commercially packaged nuts at customs. In practice, sealed manufactured nut products are nearly always cleared, but homemade or loose nut mixes may receive closer inspection. Declaring them is straightforward and the process is quick.

Some airlines have nut-free policies or allergy buffer zones on certain flights, but this is an onboard policy rather than a security or baggage rule. The restriction applies to opening and eating nuts during the flight, not to having them in your bag. Check your airline's policy if you or a fellow passenger has a severe nut allergy.

Keep nuts in sealed, clearly labelled packaging — original manufacturer bags are ideal — to make customs declarations straightforward if needed. There are no security-specific packing requirements for nuts, and they do not need to go in your liquids bag.
