Why Equipment OEMs Are Sourcing from Vietnam
Industrial machinery builders face a familiar squeeze: customers demand lower prices, but domestic machining costs keep climbing. China was the go-to for years, but Section 301 tariffs now add 25–100% to landed cost — wiping out the savings.
Vietnam offers the best of both worlds. The country has built deep machining, casting, and fabrication capability — much of it developed to serve Japanese, Korean, and European machinery OEMs who moved production there over the past decade. Today, Vietnam's factories deliver the same quality as China's best shops, at 30–50% lower landed cost to US buyers.
DEWIN has audited 179+ factories across Vietnam, with equipment lists, capability profiles, and quality scores for each. We match your parts to the right factory and manage the entire supply chain — so you get competitive pricing with full visibility and accountability.
