DAYIN Vietnam

The Vietnam line runs on the same ISO 9001-certified quality system and production practices as our China operations — group-managed and directly operated, not subcontracted.

Concretely: every transferred product goes through first-article approval before any mass run, under the same process controls our China plant has used across 35+ years of export production. You’re not betting on a young factory finding its footing.

Yes. The substantial production work is physically done at our Bắc Ninh facility, which has passed an official Vietnamese customs production-base inspection — that is what makes the origin genuine rather than relabeling or trans-shipment.

The exact certificate form depends on your destination market and applicable FTA, and we confirm it with you per order.

We’re usually not the lowest unit price, and we’ll say so up front. The number that decides your margin is total landed cost: a quote that looks 10% cheaper but runs high scrap, fails an audit, or slips a shipment costs more than it saves.

What you pay for here is a yield and a ship date you can build a program around — quoted honestly before tooling is committed, not revised after.

This is a mass-production line, not a sample shop — built for ongoing annual programs, typically from tens of thousands up to millions of units a year.

 The exact minimum depends on part size and tooling, so share your annual quantity in the form and we’ll confirm fit directly.

Yes, for finalized designs. Our injection machines run 90 to 1,200 tons, which covers most existing molds; we inspect the tool, refurbish or modify it where needed, then prove it out with T1 samples and first-article approval before committing to mass production.

Send your current tooling drawings and product specs and we’ll assess the transfer in the feasibility review.
