WASHINGTON—The Trump administration is poised to demonstrate its promised tough approach to trade rules in a long-simmering dispute with the European Union over beef.

The U.S. is considering imposing tariffs of 100% on Perrier mineral water, Vespa motor scooters and Roquefort cheese in response to the EU’s longstanding ban of American beef from hormone-treated cattle. Prompting that menu of punitive tariffs are complaints from U.S. beef producers that the EU hasn’t held up its end of a deal the two sides cut in 2009.
