In a move that could ripple across global supply chains, the Office of the U.S. Trade Representative (USTR) announced decisive action in response to years of industrial policy by the People’s Republic of China aimed at securing dominance in the semiconductor sector. The formal notice, scheduled for publication in the Federal Register on December 29, 2025, outlines a new tariff strategy under Section 301 of the Trade Act of 1974 focused on Chinese semiconductor imports.
EFFECTIVE DATE OF THE ACTION: December 23, 2025
BACKGROUND: SECTION 301 CHINA SEMICONDUCTOR
The determination follows an extensive review triggered by a December 2024 investigation into China’s regulatory and industrial practices, particularly how state-led planning, preferential support mechanisms, and market access barriers have affected fair competition within the global semiconductor landscape. China declined to engage in consultations under the statutory framework.
According to the USTR’s analysis, Beijing’s industrial planning apparatus, characterized by multi-tiered national and regional targets and broad state influence over private and state-owned enterprises, has systematically advantaged its domestic semiconductor firms in ways that degrade market competition and burden U.S. commerce. The review noted that these policies span the full semiconductor value chain, from materials and equipment to chip design and fabrication.
The USTR’s notice states that China’s practices have not only displaced foreign competitors in critical markets but also created interdependencies and vulnerabilities that pose risks to economic and supply chain resilience. As a targeted response, the USTR determined that imposing additional tariffs on certain semiconductor products imported from China is an appropriate step.
SECTION 301 TARGETED RESPONSE
The initial tariff rate has been set at 0 percent, with a scheduled increase in June 2027 to a rate that will be announced publicly at least 30 days in advance.
This phased approach seeks to balance the need to signal U.S. policy intent with the operational realities of global supply chains that depend on timely access to chips and components.
The new tariff actions will supplement existing Section 301 duties already in place on some semiconductor categories tied to past investigations, creating a layered trade remedy framework. Products affected include integrated circuits, transistors, wafers, and related devices under specific Harmonized Tariff Schedule (HTS) codes.
OVER THE NEXT 18 MONTHS
For stakeholders across manufacturing, logistics, and international trade, the USTR’s announcement underscores how industrial policy and trade enforcement intersect with supply chain strategy. Semiconductors are foundational to everything from automotive production to telecommunications to defense systems. Changes in tariff structures can alter sourcing decisions, pricing pressures, and routing strategies for global shippers, freight forwarders, and importers.
In particular, companies that integrate chips into finished goods or rely on complex multi-tiered supply networks will want to monitor how tariff timing and classification impacts landed cost and inventory planning over the next 18 months.
