A “Made in Vietnam” label is a legal claim, not a description of where the box shipped from. Vietnamese customs and the customs authorities of destination markets are both actively checking that claim right now, more closely than at any point in the past few years, and a buyer who has never asked what actually happened inside a Vietnamese factory is carrying more risk than the label suggests.

What does Vietnamese law actually require for a “Made in Vietnam” claim?
Vietnam’s own rules on the origin of goods, set out in Circular 05/2018/TT-BCT and its later amendments, require that a product either be wholly obtained in Vietnam or undergo a substantial transformation there — simple final assembly of components that already amount to a finished product is not enough on its own to make Vietnam the country of origin.
Substantial transformation is assessed against specific rules for the product category — commonly a change in tariff classification, a minimum local value-added threshold, or a defined manufacturing process, depending on the product and which agreement’s rules apply. Circular 05/2018/TT-BCT has itself been amended more than once, including by Circular 44/2023/TT-BCT and by a further amendment in 2025, so the exact test that applies to a given product should be checked against the current text rather than assumed from memory of an older version. This origin-of-goods framework is separate from, though related to, the certificate-of-origin regime that governs which document a shipment carries under a specific trade agreement — see proof of origin from Vietnam by destination market for that side of it.
The practical failure mode is a factory that receives components already substantially finished from a third country, performs only light final assembly or repackaging in Vietnam, and ships the result labelled as Vietnamese origin. Whether that clears the substantial-transformation bar depends on the specific product rule, not on the fact that the last physical step happened inside Vietnam.
Why has enforcement tightened on both the Vietnam side and the destination side?
Vietnam’s own customs authorities have visibly stepped up origin and labelling checks since 2025, at the same time as destination-country customs authorities — most visibly US Customs and Border Protection — have raised the cost of getting caught on the other end.
On the Vietnam side, the trade ministry issued a directive in April 2025 aimed specifically at illegal transshipment of goods routed through Vietnam toward the United States and other markets, and Vietnam’s customs department followed with instructions in 2026 tightening inspection and supervision of origin declarations and goods labelling. Vietnam also ran a nationwide campaign against smuggling and trade fraud over the 2025–2026 period. None of this is enforcement Vietnam is doing reluctantly under outside pressure alone — a Vietnamese exporter caught in an origin-fraud scheme risks its own export privileges, not only the shipment in question.
On the destination side, the tool a buyer is most likely to encounter by name is the US Enforce and Protect Act (EAPA), under which US Customs and Border Protection investigates allegations that antidumping or countervailing duties are being evaded — commonly through transshipment, where goods made substantially elsewhere are routed through a third country like Vietnam to acquire that country’s origin on paper. An EAPA investigation can result in duties applied retroactively and a compliance record that follows the importer, not only the exporter, into future shipments. This is a generic feature of US trade-enforcement law, not something specific to Vietnam, but Vietnam has been named repeatedly as a transshipment risk point in enforcement commentary because of its trade relationship with both the US and China.
💬 If a supplier’s pricing looks unusually good relative to a product category with known transshipment risk, that is worth a direct conversation before the first order, not after a shipment is held. Talk to us about the product.
What should a buyer actually check before relying on an origin claim?
Ask for the bill of materials by country of origin for each significant component, not just a finished-product origin statement, because the finished-product claim is only as reliable as the inputs behind it.
A factory that can produce, on request, a bill of materials showing where each significant input — fabric, a major sub-assembly, a printed circuit board, whatever the product’s key components are — was made, and can show that its own processing changes the tariff classification or adds the required value, is giving you something you can actually check. A factory that can only say “we make it here” without being able to break down the inputs is asking you to take the origin claim on faith.
Confirming the factory itself physically exists and does the processing it claims to do is the other half of this. A shell operation that receives finished or near-finished goods and repackages them under a Vietnamese address is the transshipment pattern regulators are specifically looking for, and the checks that expose it are largely the same ones that expose a fake supplier generally — a site visit or video walk showing an actual working production line on the day, not a rented office.
💬 This overlaps closely with general supplier verification. See how to verify a Vietnamese supplier remotely for the document and video-call checks, and our sourcing service for verification done in person.
Checklist before you build a sourcing plan around an origin claim
Work through these before you commit to a factory whose product category carries known transshipment attention — electronics, solar components, furniture, steel and aluminium products, and apparel have all been named in enforcement commentary in the past two years.
| Check | Why it matters |
|---|---|
| Bill of materials by country of origin for key inputs | Lets you assess substantial transformation yourself rather than taking the label on faith |
| Which specific origin rule applies to your product category | ”Made in Vietnam” is tested differently for electronics than for garments or furniture |
| Factory’s registered business lines (manufacturing vs. trading only) | A trading-only registration presented as the manufacturer is the first sign of an undisclosed party in the chain |
| Physical evidence of production on the date claimed | A video walk showing a dated production board and the actual line your order runs on |
| Consistency between quoted price and the claimed production depth | A price that only makes sense for light assembly of imported near-finished goods is a reason to ask harder questions |
Frequently asked questions
1. Does final assembly in Vietnam automatically make a product Vietnamese in origin?
No. Vietnamese origin rules require either the product to be wholly obtained in Vietnam or to undergo substantial transformation there, tested against a specific rule for the product category. Simple final assembly of an already largely finished product does not, by itself, clear that bar.
2. What is transshipment, in plain terms?
Routing goods that were substantially made in one country through a second country — with only minor processing, or none — so the shipment can be declared as originating from the second country, typically to avoid a tariff or trade restriction that applies to the true country of manufacture.
3. Who is at risk if a shipment is later found to be transshipped — the Vietnamese factory or the importer?
Both, in different ways. The Vietnamese exporter risks its own export standing and, potentially, penalties under Vietnamese law. The importer in the destination country risks retroactive duties, penalties, and a compliance record that affects how customs treats its future shipments, under mechanisms like the US Enforce and Protect Act.
4. Is asking for a bill of materials by country of origin something a buyer can reasonably request?
Yes. A factory confident in its own origin claim should be able to provide this without difficulty. Reluctance or an inability to answer is itself useful information.
5. Does a certificate of origin already confirm the product genuinely qualifies as Vietnamese-origin?
A certificate of origin confirms that Vietnam’s issuing authority accepted the origin claim on the documentation submitted to it; it does not independently guarantee that the underlying substantial-transformation test was actually met. A buyer’s own check of the bill of materials remains the more reliable safeguard.
