Department of Homeland Security DHS requires additional security measures for all international flights to or connecting through the U. Per the DHS, beginning June 30, 2018, some travelers may also be subject to additional security measures to prohibit powder-based substances greater than what would fit in a standard soda can 12 fluid ounces, 350 milliliters, 350 grams packed in carry-on bags and personal items. There are some exemptions that can be transported in carry-on luggage only if they are in a sealed, damage-free package, even if they exceed the stated volume limit including baby formula, prescription medical powders, human remains, and cosmetic powders purchased at Duty Free that are sealed and inside a STEB. Please note that some foreign governments who perform this screening at central checkpoints may follow more strict measures, including confiscating and disposing of powder-based substances in excess of permitted quantities. We recommend all customers place any items that resemble powder in checked baggage to avoid any disruption to travel. The Transportation Security Administration TSA recommends arriving at the airport at least three hours before your international flight, if possible, to allow time for the additional security measures.
