Dozens of bipartisan House members are pushing the Trump administration to allow companies to ask for exclusions from its latest round of tariffs on Chinese imports.

In a letter to U.S. Trade Representative Robert Lighthizer dated Monday, 169 representatives pushed the White House to let firms request exclusions from the duties. Last month, the Trump administration slapped 10 percent tariffs on $200 billion worth of Chinese imports, which will rise to 25 percent at the end of the year.

An exclusion process "would afford U.S. companies the opportunity to seek relief if tariffs harm their global competitiveness and would help target the effects of the tariffs on China rather than on U.S. companies and their customers," wrote the lawmakers led by Reps. Jackie Walorski, R-Ind., and Ron Kind, D-Wis. The House members noted that, under previous rounds of tariffs levied by the Trump administration, it allowed companies to request exclusions.

The letter marks only the latest congressional backlash to Trump's mounting trade war with the world's second-largest economy. Lawmakers have raised fears about the duties passing new costs on to consumers and retaliatory Chinese tariffs damaging the U.S. agricultural industry.
