Practical Answer

What Should a China Supplier Agreement Review Check Before You Sign?

A supplier, OEM, manufacturing, or supply agreement should be reviewed against the real China-side factory, contracting entity, payment path, tooling, files, and commercial structure — not only the wording on the page.

In short

A China supplier agreement review should check two layers. The first is the agreement wording: scope, quality, payment, delivery, tooling, IP, exclusivity, non-circumvention, termination, and remedies. The second is the real China-side structure: which legal entity signs, who manufactures, who receives payment, who holds the molds and technical files, and whether the agreement actually binds the parties controlling production.

A document can look acceptable while leaving the factory, payment recipient, tooling holder, subcontractor, or technical assets outside the buyer's control.

Why Contract Wording Is Only One Layer

The written terms should be tested against how the relationship operates. A contract may name the wrong Chinese entity, while the invoice and payment recipient identify someone else. An agent may control access to the real factory, and tooling or CAD/STP files may be held by another company.

Subcontractors may be outside the signed obligations. An agreement may also contain broad IP language without practical duties to deliver, return, or transfer tooling and editable technical assets. These gaps should be identified before signing or making the next payment.

What Should Be Checked?

1. Correct Chinese contracting entity

Check the complete Chinese legal name, Unified Social Credit Code where available, business licence, legal representative or authorized signatory, company chop or signing method, and whether the entity named in the agreement matches the invoice and bank account.

2. Real factory, agent, and subcontractor roles

Confirm whether the signatory is the actual manufacturer or whether a trading company or sourcing agent sits between buyer and factory. Identify subcontracted molds, PCB work, packaging, testing, firmware, or assembly, and check whether the contracting party accepts responsibility for those subcontractors.

3. Product, scope, specifications, and acceptance

Define covered products and model references, drawings, specifications, BOM, samples, packaging, approved changes, inspection, acceptance, and non-conforming goods. The agreement should state the available rework, replacement, credit, or refund process.

4. Payment path

Compare the contracting entity, invoice issuer, and payment recipient. Review deposit and milestone triggers, payments to unrelated companies or individuals, and what happens if production does not proceed.

5. Tooling, molds, CAD/STP files, and technical assets

Check ownership, possession, permitted use, return and delivery duties, transfer to a replacement factory, improvements and derivative files, and access to editable source files rather than only PDFs or screenshots. Retention or lien language should also be identified.

6. IP, confidentiality, non-use, and non-circumvention

Distinguish confidentiality from supplier-use restrictions, unauthorized manufacture, unauthorized IP filing, customer bypass, platform or exhibition sales, and use by affiliates or subcontractors. One clause does not guarantee enforcement; the result depends on the parties, documents, evidence, and execution structure.

7. Exclusivity and commercial restrictions

Check product scope, territory, duration, sales channels, exceptions, minimum volumes, supplier capacity, and consequences of breach. Exclusivity should be commercially realistic as well as clearly documented.

8. Delivery, termination, transition, and remedies

Review delivery deadlines, production delay, quality failure, termination rights, open purchase orders, tooling and file handover, transition assistance, and the evidence and notice process. China-side enforceability depends on the facts, parties, documents, evidence, and execution structure.

Agreement Review Versus New Drafting

Review may be suitable when

A usable draft already exists
The supplier supplied its own agreement
The buyer wants a focused China-side red-flag review
The main commercial structure is already understood
Revisions can be made without rebuilding the document

Agreement & Control Review

New drafting may be needed when

There is no usable agreement
The document names the wrong parties
The agreement is only an NDA or purchase order
Tooling, files, subcontractors, IP, or transfer rights are missing
The structure needs major rewriting or coordinates multiple entities

Frequently Asked Questions

What should a China supplier agreement review check?

It should check both the agreement wording and the real China-side supplier structure. This normally includes the contracting entity, factory or agent role, payment recipient, product scope, quality and acceptance terms, tooling, CAD/STP files, IP restrictions, exclusivity, subcontractors, termination, handover, and practical buyer-side control.

Can you review an agreement provided by my Chinese supplier?

Yes. A supplier-provided draft can be reviewed for China-side entity, payment, tooling, file, IP, production, and control risks. The review should also check whether the document matches how the supplier relationship actually operates.

Is checking the company registration enough?

No. Registration confirms that an entity exists, but it does not prove that the entity manufactures the product, receives payment, controls the real factory, holds the tooling, possesses the technical files, or is properly bound by the agreement.

When is review not enough?

A new agreement or major restructuring may be needed when the draft is incomplete, names the wrong parties, omits tooling or technical-asset control, fails to bind subcontractors, or does not match the real payment and manufacturing structure.

What is the difference between this review and a new China NNN or manufacturing agreement?

Use the Agreement & Control Review when an agreement, supplier relationship, PO/PI, payment path, tooling arrangement, or production structure already exists and needs to be checked. Use the China NNN & OEM Agreements service when a new China-focused agreement needs to be drafted.
