The Tariff Math Is Simple

Since 2018, US companies sourcing precision parts from China have absorbed Section 301 tariffs — now at 25% to 145% depending on the HTS code. That number sits on top of part price, freight, and insurance. Vietnam is not subject to Section 301. The landed cost difference on CNC-machined components typically runs 30–40% lower than equivalent China-sourced parts once tariffs are factored in.

China — Section 301 tariff (precision parts) 25–145%
Vietnam — Section 301 tariff 0%
EU — EVFTA tariff on Vietnam exports 0%

This is why procurement teams are running China+1 strategies right now — not because Vietnam is trendy, but because the numbers work. VNcontX operates from Bình Chánh District, Ho Chi Minh City. Cat Lai Port is under 25km from the factory floor. Air freight to LAX runs 2–3 days. Sea freight to US West Coast: 18–22 days.

What We Machine — and to What Standard

VNcontX runs DMG Mori 5-axis and Mazak QT turning centers — full capability overview at our CNC machining services page. Standard tolerance is ±0.005mm. For precision-critical features, we hold ±0.003mm. Surface finish Ra 0.8μm standard, Ra 0.4μm fine. Every shipment carries a Zeiss Contura CMM report — not a visual check, actual dimensional data.

Cpk target is ≥ 1.67 on critical dimensions. If your drawing calls out GD&T controls — flatness, concentricity, true position — we inspect to those, not just ±tolerance. The CMM report ships with the parts, not on request.

What US Procurement Teams Ask Before the First Order

These are the questions we get from sourcing engineers and procurement managers before they send an RFQ. Straight answers below.

“How do I know quality will be consistent order to order?”
Every order starts with a First Article Inspection — dimensional report against your drawing, generated by Zeiss Contura CMM. Mass production only releases after FAI sign-off. We run PDCA on any non-conformance. You get the same report on repeat orders, not just the first one.
“What if there’s a problem with the shipment?”
Direct line: duc.nguyen@vncontx.com · (+84) 906 214 789. Not a ticketing system. Our OTD is 98.4% — but when something goes wrong, you reach the production team directly.
“Does your documentation work with our receiving process?”
Standard package: Certificate of Conformance, material certifications, CMM dimensional report, and full export documentation. If your receiving department needs additional paperwork, tell us at RFQ stage — we build it into the quote.
“Lead time — what’s realistic, not what’s on the website?”
CNC standard: 7–12 business days from drawing approval. Expedited: 5–7 days. FAI samples: 3–5 days. These are actual numbers. If your timeline is tighter, tell us upfront and we’ll confirm feasibility before you commit.

Frequently Asked Questions

Everything you need to know about CNC machining in Vietnam for US companies.

Is CNC machining in Vietnam cheaper than China for US buyers?

On landed cost, yes — typically 30–40% lower once Section 301 tariffs (25–145% on Chinese goods) are included. Vietnam is tariff-free under current US trade policy.

What tolerances can VNcontX hold on CNC parts?

±0.005mm standard. ±0.003mm for precision-critical features. All tolerances verified by Zeiss Contura CMM — report included with every shipment.

How long does shipping from Vietnam to the US take?

Air freight from Ho Chi Minh City to LAX: 2–3 days. Sea freight to US West Coast: 18–22 days. The factory is under 25km from Cat Lai Port and Tan Son Nhat Airport.

Does VNcontX have ISO 9001 certification?

Yes. ISO 9001:2015 certified. Certificate available on request.

What file formats do you accept for quoting?

STEP and IGES for 3D models. PDF for 2D drawings. Send both when possible — the 2D drawing defines tolerances and GD&T callouts that the 3D model alone doesn’t capture.

Ready to Get a Quote?

Send your STEP file and drawing. We review DFM, confirm lead time, and return a detailed quote — typically within 24 hours.
