USTR Considers New Tariffs on Imported Semiconductors

USTR Considers New Tariffs on Imported Semiconductors

On May 23, 2026, U.S. Trade Representative Jamison Greer publicly stated that the Trump administration is still evaluating potential tariffs on imported semiconductors — a move intended to incentivize domestic chip manufacturing. While no immediate implementation is planned, the policy signal has triggered urgent reassessment of supply chain resilience and cost structures among global buyers. This development directly affects high-value power semiconductor exporters — particularly companies like Power Semi — across compliance pathways, pricing competitiveness, and long-term order stability in the U.S. market.

Event Overview

On May 23, 2026, U.S. Trade Representative Jamison Greer confirmed during a press briefing that the administration continues to assess options for imposing additional tariffs on imported semiconductors. The stated objective is to strengthen domestic semiconductor fabrication capacity. No formal proposal, timeline, or tariff rate schedule has been released. The statement remains at the evaluation stage and does not constitute an official rulemaking action.

Industries Affected

Direct Exporters (e.g., Power Semi–class power device manufacturers)
These firms face heightened uncertainty in U.S. market access planning. Even without active tariffs, the announcement pressures pricing strategies, customs classification reviews, and contract renegotiations — especially for long-lead, high-margin power modules where landed cost sensitivity is acute. Exposure increases for firms lacking U.S.-based assembly or testing facilities.

Raw Material & Component Procurement Firms
Suppliers of silicon carbide (SiC) wafers, packaging substrates, or specialty chemicals used in power device production may see downstream demand volatility. Buyers are beginning to stress-test dual-sourcing plans and regional inventory buffers — indirectly affecting procurement lead times and volume commitments, particularly for materials with limited alternative suppliers.

Contract Manufacturing & Assembly Service Providers
OSATs (Outsourced Semiconductor Assembly and Test) providers serving U.S.-bound power devices must now reevaluate tariff exposure under HTS codes 8541.29 and 8541.49. Though final assembly location matters, even non-U.S. OSATs risk indirect impact if their clients initiate nearshoring pilots or shift test-and-ship logistics to reduce tariff-triggering touchpoints.

Supply Chain & Trade Compliance Services
Customs brokers, tariff classification consultants, and trade analytics platforms report rising inquiries around origin tracing, rules-of-origin documentation for compound semiconductor products, and scenario modeling for Section 301 expansion. Demand is growing for real-time tariff impact dashboards tailored to discrete power components — not just logic or memory ICs.

Key Focus Areas and Recommended Actions

Review HTS Code Classification and Origin Documentation

Power semiconductor exporters should audit current Harmonized System classifications — especially for hybrid modules integrating drivers, protection circuitry, or embedded controllers. Clarify whether value-added steps performed outside the U.S. meet de minimis thresholds under proposed origin rules.

Stress-Test Pricing Models Against Multiple Tariff Scenarios

Model impacts not only on headline duty rates but also on landed cost components: increased customs bond requirements, longer inspection windows at U.S. ports, and potential surcharges from freight forwarders anticipating regulatory delays.

Accelerate Evaluation of Localized Support Infrastructure

Consider establishing U.S.-based application engineering, technical support, or small-batch qualification labs — not necessarily full manufacturing — to strengthen ‘substantial transformation’ arguments and improve commercial responsiveness amid policy uncertainty.

Editorial Perspective / Industry Observation

Observably, this is less a prelude to imminent tariffs and more a calibrated reinforcement of industrial policy signaling — consistent with prior executive orders on semiconductor supply chain security. Analysis shows the focus remains on strategic nodes (e.g., advanced logic, memory, SiC/GaN substrates), not broad-based power discrete categories. Yet Power Semi–type exporters remain exposed because their products sit at the intersection of legacy infrastructure upgrades and emerging EV/industrial automation demand — making them visible proxies in trade enforcement narratives. Current more relevant risk lies in expanded enforcement of existing Section 301 exclusions rather than new line-item duties.

Conclusion

This announcement underscores how trade policy increasingly functions as a structural lever — shaping investment decisions, R&D roadmaps, and go-to-market sequencing far beyond customs clearance. For power semiconductor suppliers, the core implication is not short-term cost shock, but medium-term recalibration of how ‘resilience’ is defined: it now includes tariff-aware design-for-manufacturing, jurisdictional diversification of test assets, and proactive engagement with U.S. trade counsel before commercial milestones.
