Is deodorant a liquid at TSA?
It depends on the type. TSA lists solid deodorant, like a stick, as allowed in carry-on and checked bags, with no size limit stated. Cream, gel, roll-on and spray count as liquids, aerosols, gels or creams, so each container has to be 3.4 oz (100 mL) or less and fit in your quart-size bag.
Try nuud: one pea-sized dab, up to 72 hours fresh, in a 15 mL tube that fits your quart bag.

The 3-1-1 rule in one minute
TSA lets you carry liquids, aerosols, gels, creams and pastes through the checkpoint in a quart-size bag, in containers of 3.4 oz (100 mL) or less. Bigger containers go in checked baggage.
What matters is the size printed on the container, not how much is left inside. A 5 oz tube with one squeeze left still counts as a 5 oz tube.
This is how TSA describes the rule on its liquids page, checked on 9 November 2026. Rules and officers can differ, so check TSA’s site before you fly.

The bin by the scanner
Most deodorants that get thrown away at security are creams, gels and sprays in full-size containers that looked fine in the bathroom. The fix is to check the size on the container before you pack, not the weight of what’s inside.
If you can’t tell, put it in the checked bag or buy a travel size.
Reapplying on a trip
Fewer reapplications is the easy way to travel
Deodorants that fade by lunchtime mean carrying one everywhere. One pea-size dab of nuud per armpit works for up to 72 hours, so you apply it once before you leave and again in two or three days.
If you’re switching from an antiperspirant, don’t switch the night before a trip. Cleveland Clinic says a change of deodorant can change the bacteria under your arms, so odor may seem stronger at first. Give your body time to adjust before you travel.
nuud and carry-on
A 15 mL tube is about half a fluid ounce
The nuud Solo tube is 15 mL, about half a fluid ounce. That is far under the 3.4 oz (100 mL) limit, so it goes in your quart bag with room to spare. One tube lasts 6 to 7 weeks, so it can live in your travel bag all year.
nuud has no aluminum, no baking soda and no fragrance, and it was tested by Derma Consult, an independent German institute, on fifty people with sensitive skin. None of them had a reaction. Read more about the cream deodorant.
Start clean and dry

Questions
Deodorant and TSA questions
Is deodorant considered a liquid?
Partly. Cream, gel, roll-on and spray deodorants count as liquids, aerosols, gels or creams under TSA’s 3-1-1 rule, so each container must be 3.4 oz (100 mL) or less in your carry-on. TSA lists solid deodorant, like a stick, as allowed in carry-on and checked bags, with no size limit stated.
Can I bring stick deodorant on a plane?
Yes. TSA’s page for solid deodorant lists it as allowed in both carry-on and checked bags and states no size limit. TSA also says the officer at the checkpoint makes the final decision.
Can I pack a big tube of cream deodorant?
Yes, in your checked bag. In carry-on, each cream, gel or paste container must be 3.4 oz (100 mL) or less and fit in your quart-size bag. Bigger containers go in checked baggage.
Does a nuud tube go in my liquids bag?
Yes. The Solo tube is 15 mL, about half a fluid ounce, well under the 3.4 oz (100 mL) limit. Put it in your quart-size bag with your other liquids.
What if the officer says no?
TSA says the final decision rests with the officer at the checkpoint. If your deodorant is in the quart bag and within the size limit, it should be fine, but a smaller container or a checked bag is the safe fallback.
Ready to stop the smell?
Start with one tube. One pea-sized dab, up to 72 hours fresh.
