Can I Bring Ammunition on a Plane to United States?

According to TSA guidelines, check with your airline if ammunition is allowed in checked bags. Small arms ammunitions must be securely packed in fiber, wood or metal boxes or other packaging specifically designed to carry small amounts of ammunition. Ask the airline about limitations or fees. Read the guidelines for traveling with firearms. When traveling, be sure to comply with the laws concerning possession of firearms as they vary by local, state and international government.
