Why We Build Wire Harnesses in the Philippines
A first-hand account of why we run our wire harness manufacturing base in Cavite, Philippines for the U.S. market: a stable U.S. trade relationship, Manila-area air and sea logistics, PEZA duty-free incentives, a cost-competitive workforce, and an established local partner. Plus how we keep sourcing from China's mature harness supply chain under PEZA, why local value-added above 40% earns a Philippine certificate of origin and lower U.S. tariffs, a real U.S. customer who moved production with identical price and quality, and how small trial orders ship and deliver.
Section 301 Tariff Workaround for Cable Assembly: A 2026 Buyer's Guide With Real Math
Every legal route US importers use in 2026 to avoid the 25–100% Section 301 surcharge on cable assemblies — country-of-origin shifting, substantial transformation rules under 19 CFR 102, certificate-of-origin documentation, FTZ withdrawals, and the routes the CBP has retroactively assessed in the last 18 months.
The Quiet Reshoring: Why 2025 Is the Year US OEMs Switch to Philippine Wire Harnesses
PEZA registrations, BOI investment data, Cavite Economic Zone occupancy, Maersk PH-US TEU growth, and the Section 301 List 4A permanence question. A falsifiable forecast for 2025.
How a Cavite Wire Harness Saves You 25% on Section 301: A Tariff Math Walk-Through
