⚖️ 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.

Decision Threshold: 100 ml (3.4 oz) or smaller container + 1 clear quart bag per passenger.
