Why Buyers Choose Dewin
What makes our on-ground Vietnam sourcing model different from trade fairs, Alibaba, or online manufacturing platforms.
50-Point Dolphin Audit on Every Factory
We don't just catalog factories — we audit them across 5 pillars and score them 0–100. Only factories meeting our minimum threshold are listed on this platform.
1,700+ Real Factory Photos
Our on-ground team photographs every factory we audit. You can see the actual workshop, machines, inspection area, and finished goods storage — not stock images.
On-Ground Bilingual Team
Vietnamese and English-speaking engineers visit factories, manage QC inspections, handle COO documentation, and give you live production updates with photos and videos.
Full FTA Documentation Support
CPTPP, EVFTA, RCEP, UKVFTA, VKFTA, and more. Our team prepares Certificate of Origin (Form B/VCCI) and FTA-specific documentation to unlock preferential tariff rates in your destination market.
Named, Transparent Factories
Unlike Alibaba or online platforms where factories are anonymous, we show you the real factory — name, location, photos, audit score, and equipment list. You know exactly who's making your parts.
50+ Manufacturing Processes
CNC machining, die casting, injection molding, sheet metal, stamping, forging, investment casting, welding, aluminum extrusion, 3D printing, assembly — all from audited factories.
