Domestically, you should be fine if you declare them to the TSA. IIRC, if there's a problem screening them, placing a coin under the urn ought to give them enough to distinguish what they are.
TSA is NOT supposed to open the container... but keep in mind the phrase "Rules! We don' need no steenken rules" Escalate as necessary.
