TSA Rule on Powder in Carry-ons

If you are in the habit of carrying any type of powder in your carry-on baggage when you travel, you need to be aware of the TSA rules. This rule has been newly rolled-out to International flights with tighter enforcement on USA flights also. While the carry-on limit on powders of 350 milliliters or roughly 12 ounces (the size of a soda can) has been enforced on domestic flights dating back to last summer, the TSA is requesting foreign airports adopt the same guidelines for international flights en route to the U.S. beginning June 30. Moving forward, passengers will need to check powders exceeding the aforementioned limit or risk being put through secondary screening. Those traveling with cosmetics, spices, protein powder and similar items will want to double check the amount before heading to the airport. "These measures are part of TSA's efforts to stay ahead of threats, keep passengers safe and constantly increase capabilities through a layered approach to security," agency spokesman Mike England wrote in an email.
