Core Viewpoint - The recent announcement by the U.S. government to impose "reciprocal tariffs" on Chinese goods has prompted a swift response from several medical device companies, which have indicated they have comprehensive plans and measures in place to address the situation. Despite the complex impacts on the supply chain, the long-term trend towards self-sufficiency and international expansion in the medical device sector remains optimistic [1][2][7].

For instance, Mindray Medical has proactively stocked products in the U.S. ahead of previous tariff increases, ensuring that current sales are unaffected by the new tariffs [2][8]. - Kaili Medical stated that the U.S. market contributes only 1%-2% to its revenue, and prior inventory preparations have mitigated the tariff impact. The company has a well-established overseas market presence [3][8]. - Dirui Medical anticipates that its direct exports to the U.S. will be around $150,000 in 2024, representing a negligible portion of its overall revenue. The company has also identified measures to minimize the tariff's effects [3]. - Leshi Medical indicated that the tariff impact is manageable, as its U.S. operations focus on digital chronic disease management solutions, which have established long-term customer relationships [3][8]. - Weili Medical reported that its exports to the U.S. account for about 15% of total revenue, with a stable business model due to long-term partnerships and necessary certifications [4].
