Solid food items (not liquids or gels) can be transported in either your carry-on or checked bags. Liquid or gel food items larger than 3.4 oz are not allowed in carry-on bags and should be placed in your checked bags if possible.

Yes, powder seasoning is allowed in hand luggage, but it is subject to the "Powder-like Substances" rule. According to TSA and international security guidelines in 2026, any powder-like substance (including spices, seasonings, or protein powders) greater than 12 ounces or 350 mL (roughly the size of a soda can) must be placed in a separate bin for X-ray screening. Security officers may need to open the container for additional testing or a "swipe" test for explosives. To minimize delays, travelers are encouraged to pack non-essential powders larger than 12 oz in their checked bags. If you are carrying smaller spice jars or seasoning packets, they can stay inside your bag, but they may still trigger a manual search if they appear "dense" on the X-ray monitor. It is always best to keep seasonings in their original, labeled packaging to avoid confusion; an unlabeled bag of white powder (like salt or garlic powder) is far more likely to cause an extended security delay and questioning than a factory-sealed container of McCormick seasoning.
