Should I move sourcing from China to Vietnam?
Moving final assembly to Vietnam changes your tariff exposure only if origin genuinely changes, which requires substantial transformation there — not relabelling. Most relocated production still depends on Chinese components, so buyers usually end up managing two supply chains and a documentation burden rather than replacing one with the other.
Diversification is sensible and, for many buyers, overdue. The mistake is expecting it to be a substitution when in practice it is an addition — and one that comes with an evidentiary burden most buyers do not budget for.
| China | Vietnam | |
|---|---|---|
| Component ecosystem depth | Very deep — most sub-tiers available locally | Thin for complex goods; components frequently imported from China |
| Tooling and engineering capacity | Extensive | Developing, concentrated in specific sectors |
| Labour cost | Higher than it was | Lower |
| Tariff position into the US | Exposed to China-specific measures | Not exposed to China-specific measures — if origin genuinely qualifies |
| Origin documentation burden | Straightforward — origin is not in question | Substantial — you must be able to evidence transformation |
| Capacity for a small buyer | Abundant | Tighter; good factories are heavily booked |
The origin question is the whole question
Country of origin is determined by where goods were substantially transformed, not where they were last shipped from or last packed. Importing Chinese components into Vietnam, assembling them minimally and exporting them as Vietnamese-origin does not achieve what the buyer hoped, and customs authorities in destination markets have been scrutinising exactly that pattern. Where origin is misdeclared the exposure falls on the importer of record — which is normally the buyer.
We will not help anyone disguise the origin of goods, restructure a shipment to obscure where it was made, or produce documentation suggesting a transformation that did not happen. We are asked, and the answer does not change. What we will do is verify what a factory in the Chinese sub-tier actually does, on the record, so that a genuine transformation can be evidenced properly by the professionals who make that determination.
The pattern that tends to work
- Keep the Chinese supply base for components and tooling, where the depth is.
- Move the operations that genuinely can be transformed, and document them properly.
- Verify the sub-tier suppliers, because they are now part of your origin story rather than an internal detail of your supplier’s business.
- Have a customs professional confirm the origin position before the first shipment, not after a detention.
