- Lyophilized powder (sealed vial)
- No. Solid form exempt from 3-1-1 rule
- Store <25°C; no refrigeration needed for trips <7 days
- COA + institutional letter + labeled vial
- Moderate. May pass if vial clearly labeled
- Reconstituted solution (<3.4oz per vial)
- Yes, but exempt under medical liquid exception if declared
- Must maintain 2–8°C continuously using TSA-compliant ice packs
- COA + institutional letter + labeled vial + declaration at checkpoint
- High. Undeclared liquids trigger automatic secondary screening
- Reconstituted solution (>3.4oz total)
- Yes. Requires declaration and reasonable quantity justification
- Must maintain 2–8°C continuously; verify ice packs frozen solid before screening
- COA + institutional letter + labeled vial + written itinerary justifying volume
- Very high. Excess volume without institutional docs raises suspicion
- Unlabeled vial (any form)
- Depends on form, but scrutiny increases regardless
- Temperature requirements unchanged
- Same as above, but lack of vial labeling compounds verification difficulty
- Severe. TSA cannot verify contents; likely confiscation or law enforcement contact
