⚖️ Why This Rule Exists: International 3-1-1 Liquid Security Rules & Container Geometry

Liquid, aerosol, and gel containers exceeding 100 ml (3.4 oz) are prohibited at the passenger checkpoint under international civil aviation security rules established after the 2006 liquid explosives plot. Because screener X-ray sensors cannot instantly differentiate benign liquids from liquid explosive precursors, volume caps are strictly enforced.

Decision Threshold: If marked container capacity is > 100 ml (3.4 oz), it must go in checked luggage unless qualifying for statutory medical or infant exceptions.
