TSA Powder Restrictions

Effective June 30, 2018, new Transportation Security Administration (TSA) requirements take effect for International flights to the United States where customers are encouraged to place powder-like substances of 12oz/350mL or more in their checked bags. Please note that 12oz/350mL is approximately the size of a standard U.S. can of soda. Powders in carry-on bags may require secondary screening, and if the powder cannot be cleared by security officials, it will be prohibited from the cabin of the aircraft.

  • Powder-like substances are described as fine dry particles produced by the grinding, crushing or disintegration of a solid substance (i.e. flour, sugar, ground coffee, spices, powdered milk and cosmetics). 
  • Certain powders will be exempt from secondary screening, including baby formula, medically necessary powders and human remains.
  • For customers departing from the United States and/or United States territories, TSA has already implemented procedures for powder-like substances at security checkpoints.
