⚖️ Why This Rule Exists: International 3-1-1 Liquid Security Rules & Container Geometry
Containers with a marked capacity of 100 ml (3.4 oz) or less that fit within a single clear, resealable 1-quart (1-liter) plastic bag are permitted through screening because small volumes can be rapidly inspected and present limited hazard potential.

⚠️ Common Traveler Mistake to Avoid
How to Avoid It: Consolidate all toiletries into one quart bag per traveler or transition to solid alternatives (shampoo bars, solid deodorant).
Does Liquid & Roll-On Deodorant Need to Be Declared at the Airport?
Standard toiletries and liquids conforming to the 3-1-1 rule (containers under 3.4 ounces / 100 ml inside a clear quart bag) require no separate declaration. You simply place the bag in a screening bin. Medically necessary liquids exceeding 3.4 ounces must be verbally declared to checkpoint screeners before inspection.
What Happens if Liquid & Roll-On Deodorant Is Confiscated or Non-Compliant?
If liquid containers exceeding 3.4 ounces (100 ml) are detected in carry-on baggage without an infant or medical exemption, screeners will not allow them past security. Travelers must surrender the item for destruction, return outside security to place it in checked luggage, or mail it home.
