Scale to 500K+ Parts Per Year.
Audited Factories. Real Capacity.
Vietnam's manufacturing sector has the depth, the equipment, and the quality infrastructure to run high-volume programs for global buyers. Dewin's 178+ audited factories prove it — not just claim it.
Why Global Buyers Scale Production to Vietnam
Vietnam isn't just a China+1 alternative — it's a mature manufacturing hub with the depth to run serious serial production programs at global quality standards.
Manufacturing Depth
From 60+ CNC machining factories to 42+ injection molding factories to 35+ sheet metal operations — Vietnam's manufacturing sector spans the full precision manufacturing spectrum. Multi-machine factories with 20–80+ CNC centers are common in our audited network.
Japanese Manufacturing Culture
A significant share of Vietnam's precision manufacturing factories were established by or trained under Japanese OEMs. 5S workplace discipline, kaizen improvement culture, and rigorous in-process inspection are common — not exceptional — in Dewin's audited network.
Global Export Documentation
Factories producing for Japanese OEMs, European tier-1s, and US manufacturers already run FAI/PPAP programs, issue material certs, and maintain lot traceability. The documentation infrastructure for high-volume export programs exists and is verified by Dewin on-site.
16+ FTAs — Competitive Duty Rates
Vietnam's FTA network gives high-volume production programs preferential duty rates across US (Section 301 = $0), EU (EVFTA), Japan/Canada/Australia (CPTPP), and UK (UKVFTA) markets. At production volumes, FTA duty savings compound significantly.
Competitive Labor & Overhead
Vietnam's skilled manufacturing labor cost remains significantly below China, Taiwan, and South Korea. Combined with lean factory structures (many factories are owner-operated with low overhead), landed cost for high-volume programs is highly competitive for both US and EU buyers.
Dewin On-Ground Presence
Our team physically visits factories — not just during audit, but during production milestones for high-volume programs. Pre-shipment inspection on every production batch, before any container is loaded. Not a virtual review. An actual inspector, in the factory, with your parts.
Factory Network Capacity by Manufacturing Process
Every capacity claim below is verified during Dewin's 50-point Dolphin Audit — Pillar 2: Equipment & Capacity. Machine count, shift schedule, and production history checked on-site.
| Process | Audited Factories | Typical Volume Range | Key Equipment Verified | FTA Markets |

All factory counts and capacities verified during on-site Dolphin Audits. Capacity ranges are typical — specific programs may exceed ranges with multi-factory coordination.
The Dolphin Audit: How We Verify Production Readiness
For high-volume programs, factory claims about capacity mean nothing without verification. The 50-point Dolphin Audit evaluates every critical dimension of production readiness.
| Dolphin Audit Pillar | Points | What We Check for Volume Programs | Why It Matters for Serial Production |
|---|---|---|---|
| Pillar 1: Facility & Safety | 10 pts | Factory floor size, storage capacity, finished goods area, safety systems | Large annual programs need physical space for WIP staging and finished goods buffer — a cramped factory creates throughput bottlenecks |
| Pillar 2: Equipment & Capacity | 10 pts | Machine count, equipment model/age, calibration records, shift schedule, maintenance logs | The most critical pillar for volume programs — machine count and shift schedule directly determine annual output capacity |
| Pillar 3: Quality Systems | 10 pts | In-process inspection equipment, calibrated instruments, defect handling procedure, NCR system | At volume, a factory without in-process inspection will ship defective batches before they're caught. Calibrated instruments and NCR processes prevent defect escape |
| Pillar 4: Workforce & Management | 10 pts | Operator training records, QC team size, management responsiveness, communication capability | High-volume programs require responsive management — issues escalate quickly at scale. Trained operators mean consistent process execution across all shifts |
| Pillar 5: Export Compliance | 10 pts | VCCI registration, COO documentation process, FTA eligibility, material origin records | For US buyers: COO compliance is not optional — every shipment must carry a VCCI Form B to claim $0 Section 301 tariff. For EU/JP buyers: FTA CO form required per agreement |
QCLDM Scoring Tiers — Production Program Eligibility
| Tier | Dolphin Score | Production Program Eligibility | Buyer Introduction |
|---|---|---|---|
| Tier 1 — Preferred | 90–100 pts | All volume programs including automotive PPAP and high-complexity parts | ✓ Priority matching |
| Tier 2 — Approved | 80–89 pts | Standard production programs; most high-volume parts; corrective actions tracked | ✓ Standard matching |
| Tier 3 — Conditional | 55–69 pts | Lower-complexity programs only; improvement plan required before high-volume programs | ⚠ Case by case |
| Probationary | 40–54 pts | Not eligible for production programs until corrective actions completed | ✗ Withheld |
| Not Listed | <40 pts | Not in Dewin network — removed pending significant improvement | ✗ Not available |
FTA Duty Advantages for High-Volume Export Programs
At production volumes, preferential FTA duty rates create significant cumulative savings across US, EU, Japanese, and Australian buyer programs.
United States — BTA + $0 Section 301
US-Vietnam Bilateral Trade Agreement + Section 301 exemption
Section 301 tariffs under the Trade Act of 1974 are China-specific. Vietnam-origin goods carry $0 Section 301 surcharge. For US buyers, this is the single biggest tariff advantage — eliminating 25%–145%+ China tariff burden on every production shipment.
CO Form: VCCI Form B · Required per shipment · Managed by Dewin
European Union — EVFTA
EU-Vietnam Free Trade Agreement
The EVFTA eliminates duties on 99% of goods traded between Vietnam and the EU over a 7-year schedule (phased from 2020). For manufacturing goods, many categories are already at zero or near-zero duty. EU buyers running high-volume production programs from Vietnam capture significant duty savings vs sourcing from non-FTA countries.
CO Form: EUR.1 Movement Certificate · Verified per shipment
Japan, Canada, Australia — CPTPP
Comprehensive and Progressive Agreement for Trans-Pacific Partnership
CPTPP covers 11 member nations including Japan, Canada, Australia, Malaysia, Singapore, and Mexico. Vietnam is a founding member. For Japanese-market buyers, CPTPP provides preferential duty rates competitive with goods manufactured inside Japan — a compelling advantage for high-volume production programs.
CO Form: Form CPTPP · Issued by VCCI per shipment
United Kingdom — UKVFTA
UK-Vietnam Free Trade Agreement
The UKVFTA mirrors the EU EVFTA in structure and provides duty-free or reduced-duty access for Vietnamese manufactured goods entering the UK market. UK-based buyers or UK-destined programs can structure COO documentation for UKVFTA tariff benefit alongside US and EU programs.
CO Form: EUR.1 (adapted) · Verified per shipment
Multi-Factory Redundancy — Built-In for Critical Programs
Single-supplier dependency is the number one supply chain risk for high-volume programs. Dewin's 178+ factory network provides built-in alternatives — all audited to the same standard.
Primary Factory
Tier 1 or Tier 2 Dolphin-audited factory matched to your volume, process, and quality requirements. Full qualification including FAI and COO documentation setup.
Qualified Backup Factory
For critical programs, Dewin qualifies a second factory in the same process category. Already audited, familiar with your quality requirements. Ready to ramp if your primary factory hits capacity or downtime.

Verified Production Buyers
"The FAI process was thorough — every dimension called out on our drawing was measured and reported. We went into production with confidence. The quality has been consistent across every batch since."
Greg L. Wilhite
President, DOMS 🇺🇸
"What differentiates Dewin is that they actually inspect the parts before they leave Vietnam. Not a paperwork review — a physical inspection. For a high-volume program, that's not optional, that's the whole point."
Francisco García Quintana
Founder, LAROME 🇺🇸
"Knowing there's a backup factory qualified for our program gives us supply chain confidence we never had with a single overseas supplier. The audit transparency is unique — we can see exactly how each factory scored."
