Why US Procurement Teams
Choose Dewin
Not another marketplace listing. Not a trade show booth. Dewin is a verified, on-the-ground Vietnam sourcing operation — 179+ audited factories, 1,700+ real photos, and a team physically in the country running pre-shipment inspections.
While platforms like Alibaba let any factory self-register, we physically visit, audit, and score every factory before you can source from them.
China-origin goods: up to 145% effective tariff rate. Vietnam-origin goods: $0 Section 301. Dewin manages COO documentation for CBP compliance.
The Problem with "Open" Sourcing Platforms
Most sourcing platforms are directories. Any factory can list. Buyers are left guessing about quality, tariff compliance, and delivery reliability.
❌ What "Open" Platforms Give You
- ✗Self-registered factories with no physical verification
- ✗Supplier-submitted photos (you don't know what you're getting)
- ✗No quality audit documentation for FAI/PPAP programs
- ✗No Section 301 COO documentation support
- ✗No on-ground pre-shipment inspection capability
- ✗Tariff compliance: entirely your problem
- ✗Anti-circumvention risk: unverified Vietnamese origin claims
✅ What Dewin Gives You
- ✓179+ factories physically visited and scored on 50 criteria
- ✓1,700+ real on-site photos taken by our Vietnam team

- ✓On-ground pre-shipment inspection before containers ship
- ✓Est. 30–50% landed cost savings vs China-sourced equivalents
- ✓QCLDM-scored factories with documented export compliance track record
Six Reasons We're Different
Not features. Verified operational realities that no open sourcing marketplace can match.
Physical Factory Audits
Every factory in our network has been physically visited by our Vietnam-based team. We score on 50 criteria across 5 pillars: Facility & Safety, Equipment & Capacity, Quality Systems, Workforce & Management, and Export Compliance.
See our vetting process →1,700+ Real Factory Photos
No stock photography. Our team photographs every factory — production floor, inspection area, specific equipment, finished goods storage. You see what you're sourcing from before placing an order.
Take a virtual factory tour →$0 Section 301 Tariff on Vietnam
Section 301 tariffs (up to 145% on some categories) are China-specific. Vietnam is not covered by Section 301. We manage Certificate of Origin documentation and anti-circumvention compliance so your CBP clearance is clean.
COO documentation guide →16+ Free Trade Agreements
Vietnam's FTA network — including CPTPP, EVFTA, RCEP, and bilateral agreements — gives your parts preferential market access in the US, EU, Japan, Korea, Australia, Canada, and more.
Tariff savings playbook →On-the-Ground Team
We have photographers, auditors, and quality managers physically in Vietnam — not managing a digital marketplace from a US office. They visit factories, run pre-shipment inspections, and manage production issues in real time.
Meet our on-ground team →Full Quality Documentation
We support FAI, PPAP, PSI, CMM reports, hardness certificates, COO, and QCLDM audit scores. Your sourcing program comes with the quality documentation your engineering and QA teams actually need.

Real quotes from real clients — sourced from documented business relationships. No anonymous reviews.
