A prolonged trade war means that for many American families, an extensive Barbie or Polly Pocket collection could soon be a luxury.

Toy-maker Mattel Inc. on Monday said it plans to raise prices in the U.S. “where necessary” on some toys and take steps to rely less on China for production, while pausing its full-year outlook as it tries to get a handle on the impact of the global trade war.

Mattel says the uncertainty about tariffs and consumer demand makes it difficult to forecast its sales and earnings for the rest of the year.
