If a quality dispute arises, under which laws should I resolve it with a Vietnamese supplier?

When we first established our sourcing team in Vietnam, we realized that vague contracts lead to nightmares. A single defect can ruin a shipment, but a weak legal foundation ruins the remedy.

For international manufacturing contracts with Vietnamese suppliers, you should generally resolve disputes under the specific laws designated in your “Governing Law” clause. If undefined, Vietnamese Commercial Law applies by default. Ideally, choose a neutral jurisdiction like Singapore or stick to Vietnamese law with arbitration at the VIAC for enforceability.

Let’s navigate the specific legal frameworks to secure your supply chain.

Should I stipulate US law or Vietnamese law in my manufacturing contract?

We often see US clients instinctively request California or New York law, but our local legal team warns against this common reflex. Enforcing a foreign ruling is incredibly difficult.
You should typically stipulate Vietnamese law or the law of a neutral Asian hub like Singapore rather than US law. While US law feels familiar, Vietnamese courts rarely enforce US judgments without a bilateral treaty. Using local law ensures your contract aligns with the jurisdiction where enforcement actually happens.

When drafting a manufacturing agreement, the instinct is often to choose the law you know best. However, our experience managing supply chains across Asia has taught us that the "best" law is the one that can actually seize assets. If you stipulate US law, you might win a lawsuit in a US court, but that victory is often symbolic if the supplier has no assets in the United States. To collect damages, you would need to take that US judgment to Vietnam, where it will likely be rejected.

This brings us to the practical reality of the "Governing Law" clause. In Vietnam, if a contract does not explicitly state the applicable law, the dispute will default to the Vietnamese Commercial Law of 2005 and the Civil Code Vietnamese Commercial Law of 2005 ¹ of 2015. These laws generally favor the jurisdiction where the seller is located. Therefore, remaining silent on this clause is a strategic error.

The Case for Singapore Law

For many of our Western clients, we recommend a compromise: Singapore Law. It is a common law system similar to the US or UK common law system ², making it understandable for Western lawyers, yet it is highly respected and enforceable in Vietnam due to strong regional economic ties. It provides a neutral ground that does not give the Vietnamese supplier a "home court" advantage while still remaining legally potent in the region.

The CISG Factor

Vietnam is a signatory to the United Nations Convention on Contracts for the International Sale of Goods (CISG). International Sale of Goods (CISG) ³ This is a critical detail. Unless you explicitly exclude the CISG in your contract, it automatically applies if your country (the US) is also a member. The CISG provides a standardized set of rules for international trade, covering remedies for non-conforming goods. This can be beneficial, as it bypasses some idiosyncrasies of local Vietnamese law, providing a more standardized international framework for quality disputes.

Comparison of Jurisdiction Choices

Is international arbitration a better option than litigation for resolving quality claims?

During a past dispute over aluminum grade specifications, we bypassed local courts entirely. Litigation is public and slow, whereas we needed a private, technical resolution.
International arbitration is significantly better than litigation for quality claims due to its finality, neutrality, and confidentiality. Unlike local courts, which may favor domestic factories, arbitration centers like the VIAC allow English proceedings and expert arbitrators. Furthermore, arbitration awards are enforceable under the New York Convention.

In the context of quality disputes, speed and expertise are paramount. When we manage projects involving complex custom parts, a quality claim often turns on technical nuances—weld penetration depth, chemical composition of alloys, or surface finish tolerances. Judges in local Vietnamese People's Courts are generalists. They may not understand the difference between a cosmetic defect and a functional failure. Arbitrators, however, can be selected based on their specific industry expertise.

The VIAC Advantage

The Vietnam International Arbitration Centre (VIAC) is the standard venue Vietnam International Arbitration Centre (VIAC) ⁴ for foreign entities doing business in Vietnam. There are several reasons why we steer our contracts toward VIAC arbitration rather than the court system:

1. Language: In a Vietnamese court, all proceedings and documents must be in Vietnamese. This adds a massive layer of translation costs and the risk of nuance being lost. VIAC allows proceedings in English.
2. Neutrality: Local courts can sometimes be subject to local protectionism, especially if the supplier is a large employer in their province. VIAC panels are generally viewed as neutral and follow international standards.
3. Confidentiality: Court cases are public. If you are disputing a trade secret or a proprietary design flaw, you do not want that on public record. Arbitration is private.

Cost and Timeline Reality

While arbitration is generally faster, it is not always cheaper upfront. You must pay arbitrator fees, which can be significant compared to the nominal filing fees of a local court. However, the "hidden" costs of litigation—years of delays, endless appeals, and lost business focus—often make arbitration the more economical choice in the long run. Under the 2010 Law on Commercial Arbitration, an arbitral award is final. 2010 Law on Commercial Arbitration ⁵ There is no appeal process, which provides certainty. In contrast, a court judgment can be appealed, dragging the process out for another year or more.

Litigation vs. Arbitration Comparison

How enforceable are foreign court judgments against a local factory in Vietnam?

We have seen competitors win lawsuits in Texas only to find the paper judgment worthless here. Without assets in the US, a Vietnamese factory can simply ignore the ruling.
Foreign court judgments are generally unenforceable against local factories in Vietnam because there is no mutual enforcement treaty between Vietnam and the US. Vietnamese courts are statistically unlikely to recognize Western verdicts, meaning you would likely have to re-litigate the entire case from scratch in the Vietnamese legal system.

This is perhaps the most dangerous misconception in international sourcing. Many buyers believe that a judgment from a respected court in the United States or Europe carries weight globally. In Vietnam, this is not the case. The Vietnamese legal system generally requires a bilateral treaty to recognize a foreign court judgment. Currently, Vietnam does not have such a treaty with the United States or many European nations.

The Treaty Gap and "Reciprocity"

Without a treaty, the only hope for enforcing a foreign judgment is the principle of "reciprocity." This means the Vietnamese court might enforce a US judgment if the US court has previously enforced a Vietnamese judgment. In practice, this is rare and difficult to prove. Consequently, if you sue a supplier in the US and win, the supplier can simply ignore the verdict as long as they have no assets in the US (like a warehouse or bank account) that you can seize. To get their money, you would have to start a new lawsuit in Vietnam, rendering your US legal fees a total waste.

The New York Convention Distinction

This is why the distinction between a "Court Judgment" and an "Arbitration Award" is critical. While Vietnam ignores most foreign court judgments, it is a member of the 1958 New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards. This means Vietnam has a treaty obligation to recognize arbitration awards from other member countries.

However, even with arbitration awards, enforcement is not automatic. The losing supplier can challenge the award in Vietnamese court on procedural grounds (e.g., they weren't properly notified). But strictly speaking, the court cannot review the merits of the case, only the process. This makes an arbitration award infinitely more valuable than a court judgment.

Administrative Leverage

Since civil enforcement can be tricky, we sometimes advise leveraging administrative law. If the quality defect involves safety violations or counterfeit materials, you can report the supplier to the Vietnamese Market Management Bureau. This triggers government audits. It is not a lawsuit, but the threat of a government shut-down or fine can be a powerful motivator for the supplier to settle the quality claim quickly.

Enforceability Risk Levels

What specific contract clauses will best protect my interests during a quality dispute?

Our engineering team drafts technical annexes just as carefully as the commercial terms. If "defect" isn't defined mathematically in the contract, no lawyer can help you later.
To best protect your interests, your contract must include a precise Definition of Defect tied to technical specs, a clear Inspection and Acceptance clause, and a specific Dispute Resolution mechanism. Crucially, add a "No Outsourcing" clause to maintain privity of contract and ensure liability remains with the primary signatory.

In our experience, legal battles are rarely lost in the courtroom; they are lost in the drafting room. When a quality dispute arises, the first thing any arbitrator will look at is the definition of "Acceptance." If your contract says payment is due upon "shipment" rather than "successful inspection," you have lost your leverage.

The "No Outsourcing" Rule

One of the most frequent causes of quality failure in Vietnam is unauthorized subcontracting. You vet a factory, audit their ISO certifications, and approve their samples ISO certifications ⁶. But when mass production starts, they farm out the work to a cheaper, unvetted workshop down the street. Under the legal principle of privity privity of contract ⁷ of contract, you have no legal relationship with that sub-supplier. You cannot sue them. You must sue the main supplier, who might claim they are not responsible for the sub-supplier's errors unless your contract holds them strictly liable. We always include a clause that explicitly forbids outsourcing without written consent and makes the primary supplier 100% liable for any sub-contracted work.

Mathematical Definitions of Quality

Vague terms like "good workmanship" or "industry standard" are useless in a dispute. In our contracts, we reference specific AQL (Acceptable Quality Limit) standards AQL (Acceptable Quality Limit) ⁸ (e.g., AQL 2.5 AQL (Acceptable Quality Limit) standards ⁹ for major defects). We attach technical drawings as binding annexes. If the aluminum bar in the photo is supposed to be Alloy 6061-T6 Alloy 6061-T6 ¹⁰, the contract must state that failure to meet this chemical composition constitutes a "material breach," entitling us to a full refund plus damages. Without this specificity, a supplier might argue that the metal is "functionally equivalent" even if it's the wrong grade.

The Power of Payment Terms

Ultimately, the best legal protection is financial leverage. We structure terms so that a significant portion of the payment (e.g., 30% to 50%) is only released after a successful third-party inspection (TPI) inside Vietnam but before shipment. This aligns with the "Law of Possession." Once the money leaves your bank account, getting it back through legal channels takes years. Keeping the money until quality is verified is faster and more effective than any lawsuit.
