Volvo Group plans to lay off as many as 800 workers at three U.S. facilities over the next three months due to market uncertainty and demand concerns in the face of President Donald Trump's tariffs, a spokesperson said Friday.

Volvo Group North America said in a statement it has told employees it plans to lay off 550-800 people at its Mack Trucks site in Macungie, Pennsylvania, and two Volvo Group facilities in Dublin, Virginia, and Hagerstown, Maryland.

The company, part of Sweden's AB Volvo, employs nearly 20,000 people in North America, according to its website.

Trump has upended the global trading system that has been in place for over 75 years with a plan for tariffs on products from across the world. His vacillating trade policy has undermined consumer and business confidence, and caused economists to raise their forecasts for a U.S. recession.

Volvo Group's lay-offs are the latest response from a car and truck industry that is reeling from the Republican president's tariffs on certain parts, which is expected to increase the cost of manufacturing vehicles.

"Heavy-duty truck orders continue to be negatively affected by market uncertainty about freight rates and demand, possible regulatory changes, and the impact of tariffs," a spokesperson for Volvo Group North America said in an emailed statement.

"We regret having to take this action, but we need to align production with reduced demand for our vehicles."
