01The rules in detail
TSA and most security agencies treat spreadable foods — peanut butter, Nutella, hummus, jam, cream cheese, soft cheeses, yogurt, honey — as liquids/gels. If you can spread it, pour it or spray it, the 100 ml rule applies. Solid foods (bread, hard cheese, chocolate bars, nuts) are unrestricted at security. Customs on arrival may separately restrict animal products.
02Tips
- Single-serve packets solve it for flights.
- Declare food on arrival where required (US, Australia, NZ, Japan).
03Frequently asked
Can I bring peanut butter in my carry-on?
Yes, with limits. Counts as a gel: jars over 100 ml go in checked bags. Small jars or single-serve packets under 100 ml are fine in the liquids bag.
Can I pack peanut butter in checked luggage?
Yes. Counts as a gel: jars over 100 ml go in checked bags. Small jars or single-serve packets under 100 ml are fine in the liquids bag.
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.
