Tariff Policy Raises Uncertainty

U.S. tariff policy is now moving on three tracks at once: Congress is pressing for tougher enforcement, allies are mapping around new import taxes, and exporters are waiting for case-by-case relief. (waysandmeans.house.gov) (commonslibrary.parliament.uk) (france24.com) On April 22, the House Ways and Means Committee held a hearing on the Trump administration’s 2026 trade policy agenda with United States Trade Representative Jamieson Greer. Chairman Jason Smith said the administration should keep “tearing down” foreign trade barriers that hurt U.S. producers and workers. (waysandmeans.house.gov 1) (waysandmeans.house.gov 2) A House of Commons Library briefing published April 14 said the United States has imposed tariffs on most UK goods entering the U.S. It said a 10% tariff applies to most UK goods, while steel, aluminium and derivative goods face a 25% tariff, and it noted U.S. investigations into pharmaceutical tariffs. (commonslibrary.parliament.uk) The same briefing said an Economic Prosperity Deal announced on May 8, 2025 would let the UK export up to 100,000 passenger vehicles to the U.S. at a 10% tariff and could remove the 25% rate on UK steel and aluminium if supply-chain conditions are met. It also said pharmaceuticals can enter the U.S. tariff-free under that deal, even as the wider U.S. tariff framework remains unsettled after a February 20, 2026 Supreme Court decision. (commonslibrary.parliament.uk) That mix of blanket tariffs, sector carve-outs and pending investigations has left companies planning around politics as much as prices. The UK library said the tariff shifts and trading-partner responses have created “a much more uncertain outlook for world trade.” (commonslibrary.parliament.uk) In China, that uncertainty is landing on factory floors already hit by the Iran war’s effect on energy and shipping costs. Reuters reported on April 16 that China’s exports grew 2.5% in March, down from 21.8% in January-February, as the conflict pushed up costs and clouded demand. (businessworldonline.com) (cnbc.com) At the Canton Fair in Guangzhou, Reuters reported on April 17 that one plastics factory had seen raw-material costs jump 20% since the Iran war began and could not fully pass those costs on to overseas buyers. Reuters also reported on April 10 that China’s producer price index rose 0.5% in March, the first factory-gate inflation in more than three years.

An Agence France-Presse report published April 23 said merchants in Guangzhou hoped a Trump visit could ease tariffs that are hitting exports of clothes, shoes and accessories. (france24.com) (cbs19news.com) The White House and U.S. trade officials say tariffs are leverage to win better access for American goods and to push trading partners into new terms. Smith made that case again at the April 22 hearing, while the UK parliamentary briefing described London’s response as a “pragmatic approach” to a more protectionist trading system. (waysandmeans.house.gov) (commonslibrary.parliament.uk) For importers and exporters, the immediate question is no longer just what the tariff rate is on paper. It is whether the next hearing, court ruling, investigation or leader’s trip changes it again. (waysandmeans.house.gov) (commonslibrary.parliament.uk) (france24.com)
