Custom Auto Parts.
40–60% Less Than Domestic.
From engine brackets to exterior trim, Dewin's Vietnam factory network delivers production-grade automotive parts with IATF 16949–level quality systems — at a fraction of US and China pricing.
Why Auto Parts Buyers Switch to Vietnam
US shops are expensive. China tariffs add 25%+ to landed cost. Vietnam offers a better path.
40–60% Cost Savings
Vietnam CNC shops run $15–25/hr vs. $85–150/hr in the US. Same machines (Mazak, Haas, DMG Mori), dramatically lower labor and overhead costs.
No China Tariffs
Vietnam is exempt from Section 301 tariffs. Auto parts face only standard MFN duty rates — vs. 25%+ additional tariffs on Chinese-origin parts.
Automotive-Grade QC
Our factories serve Tier 1 and Tier 2 automotive suppliers. PPAP documentation, Cpk data, FMEA analysis, and full dimensional inspection on every batch.
