: Effective from June 30, 2018, the U.S. Department of Homeland Security (DHS) requires additional security measures for all international flights to the U.S.A.
This results in extra screening to prevent powder-like substances of 12 ounces (approximately 350 millilitres) or larger, from being carried in the aircraft cabin.
Powder-like substances are described as being like: flour, spices, ground coffee, sugar, powdered milk and cosmetics. Passengers departing for the U.S. are required to place powder-like substances of 12 ounces (approximately 350 millilitres) or larger, in their checked in baggage.
Certain powder-like substances may be transported in the aircraft cabin provided that they are cleared at the security checkpoint, such as:
- baby formula,
- medically prescribed substances,
- human remains (ashes) and
- duty free purchases of powder-like substances (in Security Tamper Evident Bags)
