Manufacturing Contracts and IP Protection in Thailand (2026)
Importing finished goods puts most legal risk on the shipment. Manufacturing puts it on your design, your tooling and your brand. The paperwork that covers the difference is not long — but every clause below earns its place.
1. NNN, not just NDA
A plain confidentiality agreement stops disclosure. What buyers actually need is NNN: non-disclosure, non-use, and non-circumvention — so the factory cannot use your design for its own line or sell your product to your competitor. State it in Thai and English, with the Thai version controlling where enforcement will happen locally.
2. Tooling title and release
Say who owns the mould, jig and fixture; where it is stored; that it may not run for third parties; and that it is released on request within a stated number of days. Details in the tooling and mould ownership guide.
3. Specification freeze and engineering change control
Attach the drawing revision, material grade, finish and packaging spec as a schedule. Any change requires written approval and re-sampling. This single clause prevents most year-two quality drift.
4. Quality standard and remedy
Name the AQL plan, the inspection point, who inspects, and the consequence of a failed lot — rework, replacement, credit, or the right to reject and recover freight. A quality clause without a remedy is decoration. See QC and AQL.
5. Registered rights in Thailand
Trademarks and designs are territorial. Register your trademark with Thailand's DIP if your brand is applied at the factory, and consider a design registration on distinctive product form. Unregistered rights are very hard to enforce against a local counterfeit.
6. Governing law and dispute forum
For cross-border supply, arbitration usually beats foreign court judgments, because arbitral awards are far easier to enforce in Thailand than a foreign judgment. Name the seat, the rules, the language and the number of arbitrators. Related reading: supply agreements and arbitration.
7. Practical protections that beat any clause
- Split the process so no single supplier holds the whole product.
- Keep the highest-IP sub-assembly with a separate supplier or in-house.
- Own your tooling and know physically where it sits.
- Serialise and mark parts so grey-market units are traceable.
- Order in a rhythm that makes you worth keeping as a customer.
Buyer's checklist before the first PO
- NNN signed, bilingual
- Trademark filed in Thailand
- Tooling title and storage clause agreed
- Specification schedule attached and frozen
- AQL plan and remedy written
- Arbitration seat and language named
- Named manufacturing site, audited
FAQ
Is a US or EU NDA enforceable against a Thai factory?
It can be, but enforcement is slow and expensive. A bilingual NNN agreement drafted for enforcement in Thailand, with arbitration named, is materially more useful.
Should I register my trademark in Thailand if I only export?
Yes, if your brand is applied at the factory. Registration is what lets you act against local misuse and stop counterfeit exports at source.
Can I stop the factory selling my product to someone else?
Contractually, through the non-use and non-circumvention terms plus an exclusivity clause tied to volume. Practically, through owning the tooling and splitting the process.
Who owns the tooling if the factory paid for it?
The factory, unless your agreement says otherwise. Factory-funded tooling is amortised into your unit price and ties you to that supplier.
What is the single most-skipped clause?
The quality remedy. Buyers write the AQL number and forget to write what happens when a lot fails, which is exactly the moment the contract is needed.
