Why Defense & Aerospace Buyers Source From Vietnam

Domestic shops are backlogged. China is a supply chain risk. Vietnam offers precision, cost savings, and geopolitical alignment.

🎯

Sub-±0.01mm Precision

Our factories run Mazak, DMG Mori, and Haas 5-axis machines with CMM inspection (Zeiss, Mitutoyo). They hold tight tolerances on titanium, Inconel, and hardened steels daily.

📋

Full Traceability & FAI

Material certs traceable to the mill. AS9102 First Article Inspection. Serialized part marking. Dimensional reports with balloon drawings. PPAP Level 3 available.

🌏

De-Risk From China

Vietnam is a US strategic partner with 0% Section 301 tariffs. No CFIUS concerns for commercial components. Growing aerospace manufacturing sector backed by government investment.

⚠️ ITAR & Export Control Notice

Dewin manufactures non-ITAR commercial defense and aerospace components. For items controlled under ITAR (22 CFR 120-130) or EAR (15 CFR 730-774), please consult your export control officer before engaging offshore manufacturing. We are happy to review your parts list and advise on what can be sourced from Vietnam.

Frequently Asked Questions

Can Vietnam factories meet aerospace quality standards? +
Yes. Our network includes factories with AS9100D, ISO 9001, and Nadcap certifications. Many already supply tier-2 and tier-3 aerospace programs. We provide full traceability packages including material certs (MTR), first article inspection (FAI per AS9102), PPAP, and CoC documentation.
What defense-related parts can you source from Vietnam? +
We manufacture non-ITAR commercial components: vehicle brackets, enclosure housings, heat sinks, connector housings, structural brackets, optical mounts, ruggedized cases, and general mechanical assemblies. For ITAR-controlled items, consult your export control officer before engaging offshore manufacturing.
What materials do you work with for aerospace parts? +
Common aerospace materials include 6061-T6, 7075-T6, 2024-T3 aluminum, 304/316L/17-4PH stainless steel, Ti-6Al-4V titanium, Inconel 625/718, brass, phosphor bronze, and engineering plastics like PEEK, Ultem, and Delrin.
How do you ensure traceability? +
Every part gets a full documentation package: raw material certificates traceable to the mill, in-process inspection records, final CMM reports, surface finish verification, hardness testing, and serialized part marking (laser engraving, dot peen, or chemical etching) per customer spec.
What are typical lead times for aerospace parts? +
CNC machined parts: 2-4 weeks. Investment cast + machined: 5-7 weeks. Sheet metal assemblies: 3-4 weeks. Complex multi-process assemblies: 5-8 weeks. Expedited schedules available.
Are Vietnam imports subject to tariffs for defense/aerospace? +
Vietnam has no Section 301 tariffs. Aerospace components from Vietnam face only standard MFN duty rates (typically 0-2.5% for machined metal parts), compared to 25%+ additional tariffs on Chinese-origin parts. This makes Vietnam ideal for non-ITAR commercial defense and aerospace sourcing.
