U.S. tariffs squeeze supply chains

A year after renewed U.S.-China tariff friction accelerated, companies on both sides of the Pacific are still remaking how they buy, build and ship goods. A CGTN report published on May 19 said the latest round of trade tension had sent “shockwaves” through global supply chains, with one factory in Wenzhou used to show how manufacturers were adjusting operations in real time. (news.cgtn.com) Britain’s House of Commons Library, in a separate briefing published in April, said businesses were still watching U.S. tariffs on steel, aluminium, derivative exports and pharmaceuticals as trade negotiations continued. (commonslibrary.parliament.uk) Donald Trump’s tariff policy is also shaping decisions beyond China. European Union officials met on May 19 to finalize legislation needed for the bloc’s trade accord with Washington, after Trump warned the EU it had until July 4 to put the deal in place or face higher duties. (bloomberg.com) Bloomberg reported Trump had previously threatened to raise tariffs on European auto imports to 25% from 15% if implementation lagged. ### Why are companies still moving supply chains a year later? The CGTN report said the latest tariff round did not produce a one-off disruption but a longer adjustment in factory planning, sourcing and customer relationships. The report described companies in China and the United States as adapting to a commercial relationship that remained “rocky, yet unavoidable.” (news.cgtn.com) Wenzhou, the eastern Chinese manufacturing city featured in the report, was presented as a case study in how exporters are coping by changing production and trade flows rather than waiting for policy clarity. That pattern matches broader reporting this year on Chinese exporters rerouting goods and reworking sourcing to manage tariff exposure. (bloomberg.com) ### Which tariffs are still driving the cost pressure? The House of Commons Library said current U.S. trade concerns for exporters include steel, aluminium and their derivative goods, along with pharmaceuticals. Its briefing said the UK’s trade discussions with Washington focused on reducing or removing tariffs in those categories and on monitoring sector-specific arrangements, including autos. (news.cgtn.com) A Congressional Research Service update said the United States had imposed 50% tariffs since June 2025 on steel, aluminum and products containing those metals from nearly all trading partners. A White House fact sheet issued on April 2 said Trump had also signed a proclamation strengthening tariffs on imported steel, aluminum and copper and their derivatives, while a White & Case analysis said the changes widened how tariffs were calculated for many derivative products.

Companies are absorbing part of the added cost while shifting operations where they can, according to the CGTN report. The piece framed those moves as practical responses to a trading relationship in which demand continues but tariff risk remains embedded in day-to-day business decisions. (commonslibrary.parliament.uk) January reporting from The Diplomat described Chinese exporters increasingly moving goods through lower-tariff partners, underscoring how tariff policy can redirect logistics even when final demand in the United States remains intact. CNBC reported in February that Chinese factories and ports were still busy ahead of Lunar New Year, with shipments to the United States running above comparable periods in 2024 and 2025 for much of January.

AFP, via France 24, reported the EU was trying to implement its nearly year-old pact with the United States under pressure from an “increasingly impatient” Trump, who threatened steep new tariffs if the bloc missed the July 4 deadline. (news.cgtn.com) That deadline matters for companies because it affects near-term planning on autos and other traded goods. Bloomberg reported failure to complete the legislation could expose the bloc to fresh duties, and CNBC said Trump had warned tariffs could rise to “much higher” levels if the agreement was not ratified by July 4. (thediplomat.com) ### What comes next for businesses trying to plan orders and pricing? July 4 is the next fixed date in the trade calendar for companies exposed to U.S.-EU flows. EU officials were meeting on May 19 to finish the legal text needed for the accord, while the House of Commons Library said businesses were still tracking tariff treatment for metals, derivative goods and pharmaceuticals in parallel negotiations with Washington. (france24.com) For manufacturers and importers, the next step is not a single settlement but a series of policy deadlines that determine where goods are sourced, how contracts are priced and which costs companies decide to absorb.
