China Supplier
Control Review
Last updated: June 2026
Independent buyer-side review of your China supplier setup — before you scale, rely on a sourcing agent, or lose control of the factory relationship.
We help global product founders review who actually controls the factory relationship, supplier identity, China trademark position, PO / PI, payment path, contract rights, product-file control, tooling ownership, and supplier-side leverage before they move into larger production.

What We Check Before You Scale
Supplier-Control Risk Review
In short
A China Supplier Control Review is an independent buyer-side review before a founder shares product files, relies on a sourcing agent, or scales production in China. It checks supplier identity, China trademark position, NNN / OEM structure, PO / PI / payment path, product-file control, tooling ownership, and manufacturing risk.
Is This Right For You?

Know Before You Scale
Common Supplier Control Risks
Most supplier-control risks stay hidden until a problem appears. A review helps you spot them before they become expensive.
Agent controls factory access
Sourcing agent may control the real factory relationship, not you.
Wrong contract party
NNN signed with an agent or trading company instead of manufacturer.
PO / invoice risk
PO or invoice issued by trading company, not real manufacturer.
Weak exclusivity
Factory promises exclusivity, but scope may be vague or unenforceable.
Chinese name risk
Chinese brand name or product may be used by others.
Tooling and upgrade ownership
Tooling, packaging, improvements, or future upgrades may not be clearly owned.
Review Scope
What We Review
Each review covers the supplier relationship from multiple angles — identity, IP, contracts, and commercial structure.

Agent / Trading Company Role
Check whether you deal with the factory or an intermediary.
Trademark & Brand Control
Check the status of your mark, logo, and Chinese name.
NNN / Contract / Exclusivity

PO / PI / Payment Path
Check invoices, payment flow, and commercial leverage points.
Alibaba / Platform Exposure
Check whether products or brand appear on platforms or trade sites.
Tooling & Improvement Rights
Check ownership of molds, tooling, packaging changes, and upgrades.
Non-Circumvention Risk
Check whether the factory or agent can bypass you.

Buyer-Side Only. No Supplier Commissions.
Your factory is not our client — you are.
We do not earn from supplier commissions, factory markups, or sourcing fees.
A sourcing agent is paid by the supply side. We are not. That independence is what makes this review honest — one that tells you what is actually at risk, not what keeps the factory relationship comfortable.
We are not replacing your sourcing agent. We independently review whether the current structure protects your leverage, IP, contract position, and future supplier access.
FAQ
Common Questions
What is a China Supplier Control Review?
A China Supplier Control Review is an independent buyer-side review of the China-side supplier relationship before a founder shares product files, relies on a sourcing agent, or scales production. It checks supplier identity, contract structure, trademark position, payment path, product-file control, tooling ownership, and supplier-side risk.
Is this a sourcing service?
No. China IP Gateway does not act as a sourcing agent and does not take supplier commissions. The review is buyer-side and focuses on supplier-control, contract, trademark, and IP risk.
When should I request a Supplier Control Review?
Before sharing CAD files, product drawings, packaging artwork, brand materials, samples, tooling information, or large purchase orders with a Chinese supplier, sourcing agent, trading company, or factory.
Do I still need a China NNN agreement?
Often yes, but an NNN agreement is only one layer. The review helps decide whether you need an NNN, OEM agreement, China trademark filing, supplier agreement review, tooling ownership clauses, or a broader protection structure.
What documents should I prepare?
Useful documents include supplier name, website, business license if available, Alibaba or Global Sources page, quotation, PO, PI, draft NDA/NNN/OEM agreement, product description, brand name, logo, packaging files, and payment path details.
Is this the same as a factory audit?
No. A factory audit covers production capacity, quality controls, and compliance certifications. This review focuses on who controls the supplier relationship, IP ownership, contract structure, trademark status, and supplier-control risk — not factory floor inspections.
Is this the same as a China NNN agreement?
No. An NNN is an output — a contract we prepare. This review is the diagnostic step that identifies whether you need an NNN, what entity should sign it, and what else may need to be addressed alongside it.
What if I already have a sourcing agent?
That is exactly the situation where this review is most useful. When you work through an agent, the factory relationship may be controlled by the agent rather than by you. The review maps who holds what rights and whether that creates a risk.
Can you review existing PO, PI, invoices, or agency agreements?
Yes. We can include existing commercial documents in the review scope. Please note these in your inquiry so we can confirm the scope and fee.
Can this lead to NNN, manufacturing, or exclusivity agreements?
Yes. In most cases, the review identifies one or more contract gaps. We can prepare or strengthen NNN, manufacturing, exclusivity, or IP-assignment terms based on the review findings.
Should I do this before or after choosing a factory?
Either works, but earlier is better. If you are already working with a factory or agent, the review identifies existing risks before you scale. If you are still choosing, it can inform your decision.
