From RFQ to Delivered —
We Handle Everything
Dewin is a done-for-you managed sourcing service — not a directory, not a marketplace. From tariff analysis to factory selection, production oversight, QC, packing, and tariff documentation, our on-ground Vietnam team manages every step so your procurement team doesn't have to.
Your 6-Stage Managed Sourcing Process
Every Dewin engagement follows this structured process — so you know exactly what's happening at every stage.
Tariff & Factory Analysis
We review your HTS codes, calculate your Section 301 exposure, and identify which parts qualify for $0 tariff when sourced from Vietnam. We then match your requirements to qualified Vietnamese factories.
Technical Review & DFM
Our engineers review your drawings, CAD files, and technical specs. We flag manufacturability issues, suggest material alternatives, and ensure the design is optimized for Vietnamese production before quoting begins.
Factory Matching & Quoting
You are matched to one or more of our 179+ audited factories. Every factory carries a 50-point Dolphin audit score — reviewed before matching. You receive a transparent, line-item quote.
Production Oversight
Our on-ground team visits the factory during production milestones. You receive real-time updates — photos and short videos — via email at each stage. No more black-box production.
QC Inspection & Reporting
Before goods ship, our QC team conducts a full dimensional, surface, and functional inspection. You receive a written quality report with photos. We do not release goods that fail spec.
Packing, Shipping & Tariff Docs
We coordinate packing, freight, and — critically — Vietnam Certificate of Origin (COO) documentation for FTA eligibility. Post-shipment, we remain your point of contact for any issues.
Going Direct to Factories vs. Dewin Managed Sourcing
You can try to source Vietnam factories directly. Here's what that actually involves.
| Area | Going Direct to Factories | Dewin Managed Sourcing |
|---|---|---|
| Factory vetting | ❌ You find and audit factories yourself | ✅ 179+ pre-audited factories, 50-point Dolphin score |
| Language barrier | ❌ You manage communication in Vietnamese | ✅ On-ground bilingual team handles all factory communication |
| Tariff documentation | ❌ COO, FTA forms — your responsibility to navigate | ✅ Vietnam COO + all FTA documentation prepared for you |
| QC oversight | ❌ You rely on factory self-reporting | ✅ Independent QC inspection with written report |
| DFM review | ❌ Issues found after production starts — costly | ✅ Engineers review specs before quoting |
| Post-shipment support | ❌ Disputes are hard to resolve remotely | ✅ On-ground team handles resolution on your behalf |
Est. 30–50% Total Cost Savings vs. China Landed Cost
When you factor in Section 301 tariffs (currently up to 145% on some categories), Vietnam's competitive factory pricing, and the elimination of tariff costs, most US manufacturers see est. 30–50% lower landed cost when sourcing comparable parts from Vietnam.
Dewin's managed sourcing fee is typically offset within the first 1–2 shipments. You pay for a service that eliminates months of factory search, qualification risk, QC surprises, and tariff headaches — and saves you money at the same time.
