Why US Manufacturers Choose Dewin

What makes our sourcing service different from Xometry, Alibaba, or a trade fair connection.

🎯

On-Ground Team in Vietnam

Unlike sourcing platforms, our bilingual team visits factories, manages QC, and sends you real photos and videos — not just catalog listings.

🔬

50-Point Dolphin Factory Audit

Every factory in our network passes our proprietary 50-point Dolphin audit scoring Facility & Safety, Equipment, Quality Systems, Workforce, and Export Compliance.

💸

$0 Section 301 Tariff on Vietnam Goods

Section 301 tariffs are China-specific. Vietnam-origin parts land at $0 — giving you est. 30–50% lower landed cost vs. China + tariff.

📋

Complete Documentation

FAI/PPAP reports, Certificates of Origin, COO documentation for CPTPP/EVFTA/RCEP/UKVFTA — all handled by our team so your customs clearance is clean.

🚀

No MOQ on Samples

Test our factories with sample orders before committing. No minimum order quantity on initial samples — de-risk your transition from China.

🔗

Single Managed Relationship

We own the supplier relationship, QC, logistics coordination, and communication. You deal with one contact in your time zone, not 12 factories in different time zones.

Industries We Serve

Our 179+ audited factories serve clients across these verticals — all with $0 Section 301 tariff exposure.

Frequently Asked Questions

Are these reviews from real clients?
Yes. Every testimonial on this page is a verified, direct quote from a real client sourced from Dewin Technology's documented client communications. We do not fabricate or embellish client feedback — our accuracy protocol prohibits it.
How much can I expect to save by switching from China to Vietnam?
Typical savings range from 30–50% on landed cost compared to China-origin sourcing. This estimate combines lower Vietnam labor rates and the $0 Section 301 tariff on Vietnam-manufactured goods (vs. 25%–145% on China-origin parts). Exact savings depend on your HTS code, product complexity, and order volume.
What manufacturing processes does Dewin cover in Vietnam?
Our 179+ audited factories cover CNC machining, sheet metal fabrication, die casting, injection molding, investment casting, stamping, forging, welding, aluminum extrusion, 3D printing, and multi-process assembly. We match your BOM to the right certified factory.
How do I know the Vietnam factories meet quality standards?
Every factory in our network must pass a 50-point Dolphin audit covering Facility & Safety, Equipment & Capacity, Quality Systems, Workforce & Management, and Export Compliance. We only list factories that score above our minimum threshold, with Tier 1 factories scoring 90+/100.
Can I submit my own review after sourcing with Dewin?
