Yes — it's spreadable, so security treats it like any other liquid.

What about Marmite or Vegemite?

Spreadable, so same rule — 100ml in cabin, any size in checked.

Fine in cabin if they fit your 1L bag.

Short answer

All jams, jellies, marmalades, curds and preserves count as liquids because they're spreadable. The cabin limit is 100ml per jar; checked luggage is unlimited.

General guidance

Rule basis: General airport security guidance — rules can vary between airports and change over time. Confirm with your departure airport before you fly.

What to do: Pack to 100ml per container in a single 1-litre clear bag unless you've confirmed a larger allowance at both your departure airports.

Liquid Limits is a travel planning tool, not an official aviation source. Always confirm with the airport before you travel.

Will this pass the checkpoint?

Check rules

Rules vary by airport — some still enforce 100ml, others now allow 2L containers in CT scanners.

Airline

Can this travel in cabin or checked baggage?

Cabin OK

Most airlines defer to airport security on liquids in the cabin.

Border

Can you bring this into the destination country?

Usually OK

Liquids themselves are rarely a customs issue — but contents (alcohol, dairy, CBD) might be.

Three separate rule systems · Any one can stop your item

Quick answer

Cabin: 100ml jars only, inside your 1L bag. Checked: any size.

Even a half-full normal-sized jar gets refused — security goes by the jar capacity, not how much is inside.

Cabin vs checked

Type	Cabin	Checked
Hotel mini jar (~30ml)	Yes	Yes
Standard 340g jar	No	Yes
Artisan/glass gift jar	No	Yes
Fruit curd / lemon curd	100ml only	Yes

Customs & international

Sealed shop-bought jam crosses most borders fine. Heading into Australia or NZ, declare it. Honey-based preserves (see honey guide) face stricter rules.

Packing tips

Wrap glass jars in clothes, then a sealed bag
Frozen jam in checked baggage doesn't leak
Many duty-free shops sell mini jam selections after security
