China OEM Agreement: What It Is and How to Protect Yourself

An OEM (Original Equipment Manufacturer) agreement is a contract where a Chinese factory manufactures a product to your design, specifications, and brand, which you then sell as your own.

OEM is your design, built to your spec, sold under your brand. ODM (Original Design Manufacturer) is the factory's existing design with your label slapped on it. The distinction matters because it decides who owns the IP, the tooling, and the right to sell the product to anyone else.

A proper OEM agreement covers price, quality standards, IP ownership, tooling and molds, lead times, defect handling, and payment terms. It is the operating manual for the relationship — and, if a dispute lands in front of a Chinese court, it is the only thing that court will actually look at.

A US or EU template governed by foreign law and written only in English is largely unenforceable in China — the courts that can actually seize a factory's assets apply Chinese law and the Chinese text.

• •Wrong governing law — a New York or English-law clause means you must sue abroad, win, then try to enforce in China (Chinese courts rarely enforce foreign judgments). Chinese law + a Chinese court with jurisdiction over the factory is what gives you teeth.
• •English-only — if there's no controlling Chinese version, the court works from its own translation, and ambiguity favors the local party.
• •No exact legal entity — the Alibaba storefront name is not the legal entity. Without the registered company name and Chinese business licence number (USCC), you may have a contract with a company that does not legally exist.
• •No chop (公章) — a signature means little; the official red company chop is what binds a Chinese company. No chop, weak contract.
• •Vague quality and defect terms — "good quality" is unenforceable. You need measurable specs, AQL levels, and defined remedies.

1. 1Governing law + jurisdiction — Chinese law, a named Chinese court or CIETAC arbitration.
2. 2Controlling language — bilingual, with the Chinese version governing.
3. 3Exact counterparty — registered entity name + USCC number + company chop.
4. 4IP & tooling ownership — you own the molds, designs, and brand; factory cannot reuse or resell them.
5. 5Quality standard + AQL — measurable specs and inspection rights.
6. 6Liquidated damages in RMB — a defined penalty for defects or late delivery, in the currency a Chinese court enforces.
7. 7Payment terms tied to milestones — never 100% upfront; tie balances to inspection.
8. 8Confidentiality / non-circumvention — separate from a Western NDA; China needs an NNN.

Three documents, three jobs. The NNN protects your idea before you share it. The OEM or manufacturing agreement governs the production relationship. A supply or distribution agreement governs ongoing purchasing and resale downstream. Signed in that lifecycle order — NNN first, then OEM — the sequence stops the two most common ways deals go wrong.
