Who Owns Your Mold in China?
In China, a commercial invoice proves you paid for manufacturing work — it does not prove you own the mold. Ownership is decided by the written contract, so you need a bilingual mold and tooling agreement with the Chinese version governing, your company's legal name machine-engraved into the steel base plate, and an unconditional removal clause. Without them, a factory can hold your tool the moment you try to switch suppliers.
The mold you paid for might not be yours
You paid thirty thousand dollars for the mold that makes your product. It sits on a factory floor in China right now. And there is a good chance you do not own it, no matter what your invoice says.
I have spent 25 years on factory floors, and I report every week from inside Shanghai. I have watched this exact thing happen to smart, careful buyers more times than I can count. They wire the money for their tooling. The factory sends photos. The first production run comes out clean. Everything looks fine. Then the buyer tries to move production somewhere cheaper, and the factory locks the gates and keeps the mold.
This page is the full version of what I cover in the video. I wrote it so you can check every word yourself. I will tell you what I have seen with my own eyes, and I will show you what Chinese law actually says, because the two match, and because I am not going to tell you anything I cannot stand behind.
The invoice myth
Most Western buyers believe a commercial invoice and a bank wire receipt prove they own the tooling. They think, I paid for the mold, so it belongs to my company. It feels obvious. It is also wrong in China.
An invoice proves one thing. Money moved. It does not prove you own the steel. Under Chinese law, ownership of a mold is decided by the written contract between the two sides, not by who paid the bill. This is not my opinion. It sits in the PRC Civil Code, which has been in force since January 2021. If your contract says you own the mold, you own it. If you have no contract that says so, in Chinese, then whoever holds the mold has the stronger hand.
I have seen a factory look a buyer in the eye and say, the drawings are yours, but our engineers built this mold, so you only paid for materials and processing. That makes the mold jointly owned. It is a story they tell because a bare tooling line on an invoice leaves the door open for it. A clear contract closes that door before anyone can walk through it.
Why they will not call it theft
Here is the part that catches people. When a factory keeps your mold, they will not call it theft. They will call it a dispute. They will say there is an unpaid balance, or a storage fee, or that their engineers modified the tool. Each new claim buys them weeks, and weeks are what you do not have when your inventory is drying up and your shelves are going empty.
This is not fraud in the way most people picture fraud. It is a pressure play built on one simple fact. They have the steel in their building, and you do not. Possession is leverage. In my experience the factories that fight hardest to avoid a clear ownership conversation at the start are the same ones that fight hardest to keep your mold at the end. The conversation you skip on day one is the hostage situation you get on day two hundred.
One: a bilingual ownership contract, Chinese controlling
You do not protect a mold with goodwill or a wire receipt. You protect it with a proper contract and with the tool marked before production begins. Here is what I put in place, and why each piece matters.
Your contract has to say, in plain words, that your company holds sole title to the mold, no matter where it is stored. It has to be bilingual, and the Chinese version has to be the one that governs if the two texts ever disagree. This matters more than people realize. A mold ownership contract written only in English under, say, New York law is close to worthless if the factory is in Shenzhen and decides to keep your tool. Foreign court judgments are generally not enforceable in China. You want Chinese law, Chinese language, and Chinese arbitration named in the document, so the paper actually works where the mold physically sits.
Name the owner. State that ownership passes to you on payment while the factory keeps possession only to run production. List every mold and every insert by name if there is more than one, so nothing gets blurred later. Spell out that the factory cannot use your tool for anyone else, cannot use it as security for a loan, and cannot hold it against some unrelated dispute.
Two: your name cut into the steel
Stop putting stickers or paint marks on your molds. They mean nothing and they come off. Instead, make the factory machine-engrave your company legal name and a serial number deep into the steel base plate of the mold, before production starts. Not a label. Cut into the metal.
Let me be straight about what this does, because I want this page to be exact. The engraving is not a magic legal shield on its own. Your title comes from the contract. What the engraving does is give you strong, physical, hard-to-argue proof that the tool is the one named in your contract. When your legal name is cut into the steel, it becomes very hard for a factory or a rival shop to stand in front of anyone and pretend the mold is theirs. The contract is the power. The engraving is the proof that backs it up. You want both.

Three: an unconditional right of removal
The moment you tell a factory you are leaving, that is usually when the surprise fee appears. So your contract needs a clear removal clause, sometimes called a no-lien or immediate-release clause. It has to say you can send your logistics team to collect the mold on short notice, commonly forty eight hours, with no retainers and no penalty fees attached. Under Chinese law a written no-lien term paired with a clear ownership certificate carries real weight against a factory that suddenly discovers a fee at the worst possible moment.
While you are at it, put a transfer protocol in the contract too. The tool leaves with its maintenance log, its shot count, the golden samples, the spare inserts, and proper rust protection, checked against a list before it goes. A hostile factory that has to hand over the mold can still pack it badly and forget half the parts. The protocol removes that last bit of pain.
The mistake that costs the most
There is one more trap, and it catches people who did everything else right. It is not about the mold at all. It is about your brand and your design.
China runs a first-to-file system for trademarks. That means the right to a name or a mark generally goes to whoever registers it first with the trademark office, not to whoever used it first. Read that again. Your history in your home country does not protect you here. A trademark you hold in the US, the EU, the UK, or even Hong Kong gives you no protection in mainland China on its own. Hong Kong, Macau, and Taiwan are separate registries too.
So picture it. You send your design and your CAD files to a factory. Before you register anything, someone files your brand or your design in China first. Now, on paper, inside China, they own it. They can demand a payment to hand it back. They can charge you to use your own name. They can block your entry to the market entirely. Some go further and legally produce goods under your brand, because from a Chinese paperwork point of view, the mark is theirs.
The fix is not complicated, it is just a matter of doing it early and in the right order. Register your design and your brand in China, in your own company name, before you ship a single file. Not after. A foreign company without an office in mainland China has to file through a recognized local trademark agency, so start that early, because the process takes time.
What is changing, and what is not
I want this page to stay true, so here is the one thing on the horizon. China revised its Trademark Law on 26 June 2026, and the changes take effect on 1 January 2027. The revision tightens the rules on bad-faith filings and on registrations that are never actually used. That direction helps honest brand owners, because it gives you a sharper tool to cancel a squatter who never really used your mark.
But do not let that lull you. First-to-file still wins. The safe move is still the same one it has always been. File early, in your own name, before your files leave your hands. A rule that helps you claw a mark back after a fight is never as good as owning it from the start.
The bottom line from the floor
Sourcing in China rewards preparation, not assumptions. I have watched the buyer who trusted a handshake get held hostage, and I have watched the buyer who locked down ownership in bilingual writing and cut his name into the steel walk away clean whenever he wanted. The difference was not luck, and it was not a lawyer on speed dial. It was a few pages of the right contract, signed before any money moved.
Settle your mold ownership before you wire that deposit. Once the factory has your money and your steel, your leverage is gone.
Hiring an international trade lawyer to draft custom manufacturing contracts can easily run you over a thousand dollars. To save you that, I put together the two agreements I use with my own clients, translated into precise legal Chinese and ready to use today.

This article reflects what I have seen in 25 years of sourcing and how mold ownership and trademark rules work in China as of September 2026, drawn from Chinese contract and trademark law and current industry practice. It is general guidance from my own experience, not legal advice. For your own situation, have a qualified lawyer draft or review your tooling agreement.
Frequently asked questions
If I paid for a mold in China, do I own it?
Not automatically. Under the PRC Civil Code, ownership of a mold is decided by the written contract between the parties, not by the invoice. An invoice proves you paid; it does not prove you own the steel. If you do not have a contract that clearly states you own the mold, in Chinese, the factory that holds it has the stronger position.
Can a Chinese factory legally keep my mold?
If your contract lacks a clear ownership clause and a no-lien or immediate-release clause, a factory can hold your mold and frame it as a dispute over fees rather than theft. With a written ownership certificate and a no-lien clause under Chinese law, you are in a far stronger position to force release.
Why does the mold contract have to be in Chinese?
Foreign court judgments are generally not enforceable in China. A mold ownership agreement written only in English under foreign law is close to useless if the factory is in China and decides to keep the tool. You want a bilingual contract with the Chinese version controlling, Chinese law, and Chinese arbitration named, so the document works where the mold physically sits.
Does engraving my name in the mold protect it legally?
Engraving is strong physical proof, not a standalone legal shield. Your title comes from the contract. Machine-engraving your company legal name and a serial number deep into the steel base plate gives you hard-to-argue proof that the tool is the one named in your contract, which makes it very difficult for a factory or rival shop to claim it is theirs. Use the contract and the engraving together.
Can a factory in China register my product or brand before I do?
Yes. China uses a first-to-file trademark system, so the right generally goes to whoever files first with CNIPA, not whoever used the mark first. A trademark you hold in the US, EU, UK, or Hong Kong gives no protection in mainland China on its own. If a factory files your brand or design first, they can block your market entry or charge you to use your own name. Register your design and brand in China, in your own company name, before you ship any files.
Is China's trademark law changing in 2026 or 2027?
China revised its Trademark Law on 26 June 2026, effective 1 January 2027, tightening rules on bad-faith and non-use filings. This helps genuine brand owners cancel squatters more easily, but first-to-file still wins. The safe move is unchanged: file early, in your own name, before your files leave your hands.
