As per the U.S Department of Homeland Security (DHS), effective 30th June 2018, passengers traveling on flights bound for the United States may be subjected to additional security measures to prohibit powder-based substances greater than 12oz/350ml in carry-on baggage. If the powder substance is in excess of the allowed amount, it is not allowed in the cabin of the aircraft.
We recommend all customers place any items that resemble powders in checked baggage to avoid any disruption to travel. For ease of travel, TSA recommends placing larger items in checked baggage prior to arriving at the security checkpoint
Examples of powders subject to the 12oz/350 ml carry-on restriction include:
Ground coffee or tea
Cosmetics (in powder form)
Exempted items that must be identified, screened and resolved include:
Medically necessary powders (including protein powder)
Powders purchased after the security checkpoint, such as bagged coffee purchased at duty-free shops, are exempted only if they are placed in security tamper evident bags. Otherwise, the powder will have to be gate checked or abandoned.
These enhanced security measures are part of a continued effort to raise the baseline on global aviation security and align domestic and international aviation security procedures.
Kindly disseminate this information to your team and affected travellers.
