Fast from Verified Factories —
Not Just Fast Promises
Every lead time below reflects real production schedules from 178+ audited Vietnamese factories — with Dolphin-certified QC inspection included. No surprises, no middlemen, no guesswork.
Why Our Lead Times Are Reliable
We quote lead times based on factory capacity we've verified in person — not marketing promises.
On-Ground Factory Access
Our team physically visits factories before and during production. We track capacity in real time — not via email.
QC Built Into Every Timeline
All lead times include pre-shipment inspection by our Dolphin-trained auditors. You never receive uninspected parts.
Real-Time Production Updates
You get production photos and progress reports — not silence. We send updates at tooling approval, first article, and pre-ship.

Lead Time FAQs
How fast can Vietnamese factories produce parts?
Standard lead times for CNC machined parts from our audited factories are 5–10 production days. Expedited orders can be completed in 3–5 days depending on complexity and material availability.
How long does shipping from Vietnam to Global take?
For visitors in Global, shipping times are roughly: Air Express: 4–7 business days, Sea Freight: 20–45 days.
Does Dewin include quality inspection in the lead time?
Yes. Our on-ground team conducts dimensional inspection, visual check, and review of material certifications before any shipment leaves the factory. QC inspection typically adds 1–2 days to the production lead time.
How many factories are in the Dewin Vietnam network?
178+ audited Vietnam factories across 50+ manufacturing processes. Every factory has completed a 50-point Dolphin audit before joining our network.
