Why Machinery OEMs Are Moving to Vietnam

Domestic lead times are months long. China tariffs kill margins. Vietnam is the smart alternative.

💰

40–60% Cost Reduction

Vietnam machine shops run $15–25/hr vs. $85–150/hr in the US. For high-mix, low-volume industrial parts, the savings are transformative — without sacrificing quality.

🛡️

0% Section 301 Tariffs

Industrial machinery parts from Vietnam face only standard MFN rates (0–3.5%). Chinese-origin parts carry 25%+ additional tariffs — erasing any cost advantage.

🏭

Heavy-Duty Capability

Our network includes factories with floor boring mills, 5-axis gantry machines, 20-ton cranes, and heavy fabrication bays. Parts from 50g to 500kg+ — no problem.

Frequently Asked Questions

What types of industrial machinery parts can you manufacture? +
We produce everything from hydraulic manifolds and gearbox housings to machine frames, conveyor components, pump bodies, spindle parts, and custom fixtures. Our factory network covers CNC machining, casting, sheet metal fabrication, and full assembly.
Can you handle large or heavy parts? +
Yes. Our network includes factories with CNC machines handling workpieces up to 3,000mm, floor-type boring mills, and heavy fabrication shops with 20-ton crane capacity. We routinely produce parts from 50g to 500kg+.
What materials do you work with for industrial parts? +
Common materials include 4140/4340 alloy steel, 303/304/316L stainless steel, AL6061/7075, cast iron (GG25/GG30), bronze (C95400/C93200), and engineering plastics like POM, PEEK, and Nylon 66-GF.
How do you ensure quality for precision industrial components? +
All factories in our network undergo on-site audits. We provide full dimensional inspection reports (CMM), material certs (MTR/mill certs), hardness testing, and surface roughness verification. FAI and PPAP documentation available on request.
What are typical lead times? +
CNC machined parts: 2-4 weeks. Cast + machined parts: 4-6 weeks. Sheet metal fabrication: 2-3 weeks. Complex assemblies: 4-8 weeks. Rush orders available at additional cost.
Are Vietnam imports subject to tariffs? +
Vietnam has no Section 301 tariffs. Industrial machinery parts from Vietnam face only standard MFN duty rates (typically 0-3.5%), compared to 25%+ additional tariffs on Chinese-origin parts.
