How the ROI Model Works

Three savings levers — each independently defensible, each verifiable from public data.

🚨

Lever 1: Section 301 Elimination

Section 301 tariffs add 7.5%–25% on top of normal MFN duties for Chinese-origin goods. Vietnam-origin goods carry $0 Section 301. This is the highest-certainty savings driver — rates are published by USTR.

China spend × China% × move% × tariff rate
= Annual tariff savings

Lever 2: Unit Price Differential

Vietnam manufacturing labor and overhead costs are typically 15–30% lower than equivalent Chinese factories for precision processes like CNC machining, die casting, and stamping. This estimate is based on documented price comparisons.

China spend × China% × move% × price diff%
= Unit price savings
🔄

Lever 3: Transition Costs (Deducted)

Upfront costs are real: tooling, first article qualification, PPAP documentation, and buffer inventory during the parallel-run period. The calculator deducts all Year 1 costs so the ROI is honest — not marketing math.

What US Manufacturers Say

"

The tariff math was undeniable. Once we ran the numbers on our CNC components, moving to Vietnam was the only logical choice. Dewin made the transition straightforward.

We were paying 25% Section 301 tariffs on every steel part we imported. Vietnam gave us the same quality, faster lead times, and zero tariff exposure.

I was skeptical about Vietnam manufacturing quality. The Dolphin audit reports and factory photos changed my mind before I even placed a first order.

Frequently Asked Questions

How is the 5-year ROI calculated? ▾
Three drivers: (1) Section 301 tariff elimination (USTR-published rates, 7.5–25%); (2) unit price differential (est. 15–30% lower Vietnam labor + overhead); (3) minus Year 1 transition costs (tooling, qualification, buffer). Net ROI = total 5-year savings minus transition costs. All estimates labeled as such.
What is Section 301 and why does it only apply to China? ▾
Section 301 tariffs were imposed under the Trade Act of 1974 specifically targeting Chinese-origin goods. Vietnam-origin goods carry $0 Section 301. Depending on your HTS chapter, moving from China to Vietnam eliminates 7.5–25% in additional duties on every dollar you import.
How accurate are the savings estimates? ▾
The tariff savings figures use published USTR Section 301 rates — precise. The unit price differential (15–30%) is a documented estimate based on Vietnam vs. China labor cost comparisons. We label all estimates — use this as directional, then request a detailed quote for your specific parts.
What does Dewin charge for the transition? ▾
No upfront consulting fee. Dewin earns a margin on parts — the same model as any managed sourcing partner. Our service includes factory matching, 50-point Dolphin Audit, First Article Inspection, PPAP documentation, and COO management. Tooling costs are direct and reflected in unit pricing.
How long does a China-to-Vietnam transition take? ▾
With Dewin's pre-audited factory network, most clients receive first article samples in 8–14 weeks. Full qualification including PPAP and COO documentation typically takes 4–10 months. Many clients run China and Vietnam in parallel during transition to eliminate supply risk.
