Rio has been available to the US market since 2002 providing American Sportsmen and Women with high quality affordable shotgun cartridges in various gauges and for various activities.

Rio's parent company MAXAM is a global leader in the explosives industry and supplies munitions to civil, military, and sporting markets in more than sixty countries. In June 2015 Rio opened a start-of-the-art 105,000 square foot North American facility in Marshall, Texas assembling a wide range of hunting and target loads for the North American market.
