When traveling by air, cosmetics packed inside hang luggage must comply with Transportation Security Administration rules. Since August 10, 2006, these rules apply to all liquids, gels and aerosols that pass through airport security. Limited quantities are allowed in the one piece of hand luggage a traveler may bring on board. The TSA established the 3-1-1 rule for hand luggage: 3.4 ounce (100ml) bottle or less (by volume) ; 1 quart-sized, clear, plastic, zip-top bag; 1 bag per passenger placed in screening bin.
The maximum size container for all liquids, gels and aerosols must not exceed 3.4 oz. (100ml). Half-full or rolled-up toothpaste tubes exceeding this size are not allowed.
All cosmetics that are liquids, gels and aerosols must be stored inside one quart-size, zip-top, clear plastic bag. Not permitted are the gallon-size plastic bags or non-zip sandwich bags. Only one clear plastic bag per traveler is allowed.
At the security checkpoint, every flight passenger must remove his quart-sized plastic, zip-top bag from his hand luggage and place it inside a bin or on the conveyor belt for X-ray screening.
Cosmetic liquids, gels or aerosols inside containers larger than 3.4 oz. ounces must be declared at the airport security checkpoint.
