Throughout 2025, a series of US tariff actions significantly reshaped the supply chain economics for polyphenylene ether used in PCB manufacturing. Initially, an additional 10% reciprocal tariff was imposed on Chinese-origin goods effective March 4, 2025, eliminating de minimis exemptions and triggering formal consumption entries for PCB components valued under $800. This measure was compounded on April 9, 2025, when reciprocal duties surged to 125%, augmenting existing Section 301 and IEEPA levies and driving manufacturing costs upward due to both higher landed prices and increased customs formalities.

In a subsequent bilateral agreement, the United States and China agreed to reduce reciprocal tariffs to 30% on two- and four layer FR-4 rigid PCBs and to 55% on other PCB types, effective May 14, 2025. Despite this relief, multiple layers of duty-including base MFN rates, Section 301 spectrums ranging from 7.5% to 25%, and the 20% IEEPA tariff-remain in force, complicating cost projections for resin imports and incentivizing the exploration of alternative sourcing strategies in regions outside China. The cumulative effect of these measures has forced PCB fabricators and resin compounders to re-evaluate inventory policies, accelerate qualification of non-Chinese resin grades, and engage in more dynamic tariff risk management to preserve margin ceilings and supply continuity.
