Fast from Verified Factories —
Not Just Fast Promises
Every lead time below reflects real production schedules from 179+ 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.

QC is Built In — Not an Add-On
Before any part ships, our on-ground Dolphin auditors conduct a pre-shipment inspection against your drawing tolerances and cosmetic specs. This is included in every order — no extra charge.

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 the US take?
Air freight from Ho Chi Minh City (HCMC) to major US hubs takes 3–5 business days via express courier, or 5–8 days via standard air. Ocean freight takes 18–25 days to the US West Coast and 25–32 days to the US East Coast.
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 adds 1–2 days to the production lead time and is included in every order.
Can I request a factory-specific lead time before committing?
Absolutely. When you submit an RFQ, we match your part to specific factories in our network and provide factory-confirmed lead times — not estimates based on averages.
Are these lead times for first orders or repeat orders?
Tooling lead times apply to first-time orders requiring new tooling (molds, dies). Production lead times for repeat orders are typically 30–50% shorter once tooling is in place and factory approval is confirmed.
