US President Donald Trump signed an executive order on Thursday, imposing a 15% tariff on imported products made from polysilicon, a crucial material for semiconductors and solar panels. The order, which also sets minimum import prices on polysilicon and related products, is a direct measure to counter China’s near monopoly in global production and protect American manufacturers, marking a significant escalation in the technological and economic rivalry between Washington and Beijing.
Strategic Tariffs and Domestic Production Incentives
The executive order, due to take effect in December, follows a comprehensive national security investigation into the production of polysilicon overseas. President Trump explicitly stated that the US has for decades ‘allowed foreign firms to weaken United States producers in the polysilicon sector,’ highlighting the material’s indispensable role in military equipment and electronics. This policy shift aims to reverse a dramatic decline in US manufacturing capacity, with the nation’s share of global polysilicon production falling from 50% in 2005 to less than 2% in 2024.
The measures, which include both the 15% tariff and minimum import prices, were based on recommendations accepted by President Trump from Secretary of Commerce Howard Lutnick. In addition to these import restrictions, the US government plans to offer incentives specifically designed to boost domestic polysilicon production. This dual approach is expected to provide a substantial lift to US-based producers such as Hemlock Semiconductor and Wacker Chemie, identified as the main domestic manufacturers of the material.
Escalating Geopolitical Tensions and International Reactions
The imposition of these tariffs reignites trade tensions that had been largely on hold since May 2025, placing the production of computer chips—central to the race to develop artificial intelligence (AI)—at the forefront of the US-China strategic competition. The Chinese embassy in Washington swiftly condemned the action, asserting that the move ‘seriously disrupts’ trade between the two nations and accusing Washington of ‘abusing state power to go after Chinese businesses.’ The embassy further contended that ‘protectionism will not make the US more competitive’ and affirmed Beijing’s commitment to act to protect its companies.
Analysts quoted by the Chinese state media outlet Global Times interpret the new tariff as the latest escalation in Washington’s concerted efforts to limit China’s influence across critical technology supply chains. This move aligns with a series of earlier US restrictions targeting imports of drones, humanoid robots, and other advanced technology products from China, underscoring a persistent pattern of strategic decoupling in key sectors.
Beijing’s Countermeasures and Future Outlook
In a reciprocal fashion, China has already announced its own range of countermeasures this week. These include tighter export controls on drones and the initiation of a national security review into imported printers and copiers, signaling a continuing tit-for-tat dynamic that defines the economic relationship between the world’s two largest economies.
As the December implementation date approaches, the new tariffs on polysilicon underscore the deepening strategic competition over critical technological materials. This action highlights the US administration’s commitment to re-shoring vital supply chains and directly confronting China’s industrial dominance, ensuring that the technology sector remains a primary battleground in global economic policy.
