What the Checklist Evaluates

8 dimensions that determine how well your parts will fit Vietnam manufacturing — and how much you can save.

🔩
Process Fit
Does Vietnam have the right manufacturing process? (CNC, casting, sheet metal, molding, etc.)
🇨🇳
Tariff Exposure
Current Section 301 tariff rate on your parts — the primary savings lever.
💰
Program ROI
Annual spend size determines whether tooling + transition costs pay back quickly.
📐
Tolerance Achievability
Do Vietnam factories have the inspection equipment to hold your tolerances?
📦
Volume Fit
Vietnam factories optimize for production runs of 500+ units. Low volumes need extra evaluation.
📋
Documentation Requirements
FAI, PPAP, COO — Dewin manages all of these. ITAR-controlled parts are flagged early.
⏱️
Transition Timeline
Urgency affects factory match priority and whether expedited qualification is needed.
🎯
Overall Qualification Score
Composite score from all 7 dimensions — determines factory match tier and priority.

Buyers Who've Qualified Their Parts Through Dewin

★★★★★

"We needed a dual-source for CNC turned shafts. Dewin matched us to a factory with a CMM on-site, ran FAI, and we had approved first articles in 8 weeks. Section 301 savings alone justified the switch."

Francisco García Quintana
LAROME
★★★★★

"The part qualification process was thorough. They mapped our BOM to two factories, coordinated PPAP Level 2, and managed the COO documentation. We avoided $110K in Section 301 tariffs in year one."

Greg L. Wilhite
DOMS
★★★★★

"I was skeptical that Vietnam could hold our tolerances. Dewin showed us factories with CMMs and VMMs before we committed. The FAI came back cleaner than what we were getting from our China supplier."
