These converging forces are reshaping both the technological and competitive contours of the glass substrate PCB landscape.

In 2025, U.S. trade policy has exerted profound effects on the glass substrate PCB supply chain as tariffs on Chinese-origin PCBs and related components remain in flux. Under Section 301, traditional 2- and 4-layer rigid PCBs initially faced duties as high as 145 percent, while multi-layer and flexible types saw rates up to 170 percent. A temporary 90-day tariff moratorium announced in May 2025 reduced certain PCB tariffs to 30 percent, alleviating some immediate cost pressures. However, U.S. companies continue to navigate a complex mosaic of variable duties-ranging broadly from 30 percent to 55 percent depending on board type-as policymakers reassess trade balances.

Consequently, many original equipment manufacturers and contract fabricators have accelerated the relocation of production capacity to Southeast Asia, particularly Vietnam, Thailand, and Malaysia, to mitigate the impact of U.S. duties. This geographic shift presents challenges in quality control and supply chain integration, while prompting domestic suppliers to expand local manufacturing capabilities to capture nearshoring opportunities. Furthermore, preliminary anti-dumping measures on epoxy resins-integral to copper-clad laminates-impose additional duties exceeding 350 percent on certain Chinese resin imports, driving up foundational material costs and reinforcing the strategic importance of diversified sourcing strategies.

A nuanced understanding of the glass substrate PCB market demands careful examination across multiple dimensions of segmentation.
