How does Dewin match my quote to the right Vietnam factory?

After you configure your process, material, and quantity, our team searches our 179+ audited factory network by: (1) process capability match, (2) equipment verification (we've physically visited and photographed every factory), (3) certification match (ISO 9001, IATF 16949, AS9100D as needed), (4) current capacity and lead time availability, and (5) QCLDM Dolphin Audit score — we only quote from Tier 1 and Tier 2 factories.

What FTA benefits apply to Vietnam manufacturing?

Vietnam has 16+ active Free Trade Agreements including CPTPP (covering US, Canada, Australia, Japan, NZ, Mexico), EVFTA (EU27 + UK via UKVFTA), RCEP (ASEAN + China, Japan, Korea, Australia, NZ), and bilateral FTAs with individual markets. These FTAs provide reduced or zero duty rates for Vietnam-origin goods exported to most major economies. Our team manages COO documentation to ensure your shipments qualify.

What quality documentation does Dewin provide?

Every Dewin order includes: Pre-shipment inspection (PSI) report, dimensional inspection records (CMM or VMM where available at the factory), Certificate of Origin (VCCI Form B or FTA-specific CO), material certificates, and packing list. PPAP, FAI, and third-party lab reports are available on request.

Q: What is the 50-point Dolphin Audit?

The Dolphin Audit is Dewin's proprietary factory verification framework covering 5 pillars: (1) Facility & Safety, (2) Equipment & Capacity, (3) Quality Management System, (4) Workforce & Management, (5) Export Compliance & COO Documentation. Each factory is scored across 50 criteria and assigned a QCLDM tier (Tier 1: 90–100, Tier 2: 75–89, Tier 3: 60–74). We only quote from Tier 1 and Tier 2 factories.

Q: Do I need a CAD file to get a quote?

No. Use the Quick Configure path to select your process, material, quantity, and finish and get an instant price estimate without files. Our team confirms exact pricing within 2–4 business hours. Uploading a STEP, IGES, STL, DXF, or PDF file allows us to provide a more precise quote with DFM feedback.

Configure your part and get an instant price estimate matched to our physically verified, 50-point Dolphin Audited factory network. No CAD file needed to start.
