British officials also announced more financing for exporters as the country sought to protect firms hurt by tariffs.
The British government ramped up actions to help protect businesses and households from some of the economic tumult created by President Trump’s decision to raise tariffs and upend the norms of global trade.
The government said on Sunday it would suspend tariffs on 89 products for about two years to help businesses and consumers save money. The products include those for construction, such as plywood and plastics, and everyday household items, such as pasta and fruit juices.
Officials will also increase financing support for exporters by 20 billion pounds ($26 billion), through partial loan guarantees, and give small businesses access to loans of up to £2 million.
As Mr. Trump raises tariffs on most imports, including those from Britain, to a 10 percent base line and even higher for certain goods like cars and steel, the British government has sought to calm anxieties at home. Officials have said they want to move quickly to support companies as they try to sustain fragile economic momentum.
“This week, we witnessed the uncertainty of a changing world,” Rachel Reeves, the chancellor of the Exchequer, wrote in The Observer, a Sunday newspaper. In response, the government “must rise to meet the moment,” she wrote.
The announcements on Sunday followed other interventions by the government in recent days to bolster protections for firms affected by tariffs. On April 6, the government eased rules on electric vehicle sales after Mr. Trump imposed a 25 percent tariff on cars imported into the United States. British officials also relaxed regulations to speed up timelines for clinical trials to support the life sciences sector with Mr. Trump also expected to impose levies on the pharmaceutical industry.
