Lawsuits against the Trump administration have piled up over the last fortnight as some 3,500 American firms, including auto majors, retailers and pharmacies, were reported to challenge US tariffs on billions of Chinese goods.

The suits, filed by a wide range of companies in the US Court of International Trade in New York, seek to declare unlawful the latest rounds of levies on Chinese products imposed by Washington amid a wider trade dispute with Beijing. According to a Reuters report citing the filings, they name the US trade representative, Robert Lighthizer, and the Customs and Border Protection agency as defendants.

Some of the companies accuse the Trump administration of waging an “unbounded and unlimited trade war impacting billions of dollars in goods imported from the People’s Republic of China by importers in the United States,” while others point at officials’ failure to comply with administrative procedures and impose tariffs within a required one-year period.
