The cumulative impact of multiple U.S. tariff initiatives enacted in 2025 has introduced unprecedented complexity into wire harness PVC compound supply chains and cost structures. First, the extension of legacy Section 301 tariffs on Chinese imports remains in effect through May 31, 2025, with a new 20% IEEPA tariff taking effect on March 4, 2025. These measures continue to apply to a broad range of chemical intermediates and polymer resins, limiting the pool of competitively priced suppliers available to North American compounders.

Compounding these constraints, an Executive Order issued on April 2, 2025 imposed a 10% reciprocal tariff on the import of all goods-subject to exclusions-effective April 5, 2025. Shortly thereafter, the tariff on Chinese-origin goods spiked to 125% on April 9, 2025, only to be recalibrated following a trade deal in Geneva on May 12, 2025 that reduced reciprocal tariffs on China to 10%. While this deal paused reciprocal increases for most trading partners until July 8, 2025, the volatility of rates has forced manufacturers to adopt dynamic sourcing strategies and integrate tariff escalation clauses into supply agreements.

In addition, Section 232 tariffs on steel and aluminum products, including specialty alloys used in conductor materials and connector housings, continue at 25%, elevating costs across the electrical component value chain. Anticipation of potential 25% tariffs on Canadian and Mexican imports-proposed under separate authority-has further incentivized producers to diversify production away from traditional North American Free Trade trading blocs. Sumitomo Electric has publicly warned that threatened tariffs on Mexican-sourced wire harness components could lead to a shift of production to Southeast Asian countries where duty rates remain lower.

As a result, compounders are grappling with layered duties, fluctuating exclusion periods, and shifting bilateral agreements that complicate landed cost calculations. The cumulative tariff burden has driven purchasers to explore alternative resin grades, negotiate long-term contracts with supply guarantees, and invest in domestic compounding capacity to mitigate exposure to ongoing trade policy uncertainty.
