Powders are described as fine dry particles produced by the grinding, crushing, or disintegration of a solid substance. For example, flour, sugar, ground coffee, spices, powdered milk (such as baby formula), and cosmetics.
For trips to or with connection to the United States, containers with powder greater than 12 oz (350ml) are not allowed in the carry-on bag, except for powdered medicines with prescription, milk formula for babies and human remains that are in fully sealed containers are allowed. Otherwise, the container should be inspected for signs of tampering.
