What Can I Bring?

Fresh flowers are allowed through the checkpoint without water.

Formaldehyde solutions of less than 10% are not restricted as hazardous materials. Leak-proof packaging with absorbent material is still strongly encouraged.  For formaldehyde solutions containing more than 10% formaldehyde, see separate entry for "Biological specimens in preservative solutions."

Tip: Full-strength "Formalin" is typically 35%-40% formaldehyde by volume. So a solution that is less than 25% Formalin would be less than 10% formaldehyde and not restricted.

Frozen liquid items and gel packs are allowed through the checkpoint as long as they are frozen solid when presented for screening. If frozen liquid items are partially melted, slushy, or have any liquid at the bottom of the container, they must meet 3-1-1 liquids requirements.

TSA officers may instruct travelers to separate items from carry-on bags such as foods, powders, and any materials that can clutter bags and obstruct clear images on the X-ray machine. Travelers are encouraged to organize their carry-on bags and keep them uncluttered to ease the screening process and keep the lines moving.

Solid food items (not liquids or gels) can be transported in either your carry-on or checked bags within the continental United States. 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.

Passengers flying from Hawaii, Puerto Rico, or the U.S. Virgin Islands to the U.S. mainland cannot take most fresh fruits and vegetables due to the risk of spreading invasive plant pests.
