China Supplier
Control Review

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.

What if I paid for molds or tooling, but the Chinese factory controls them?

This is a common supplier-control issue. Payment alone may not be enough if the contract, invoice, PO, and manufacturing terms do not clearly address ownership, use restrictions, return, transfer, storage, and inspection. A Supplier Control Review can help identify what documents support your position and what gaps remain.

What if I paid for a prototype, but the supplier refuses to provide drawings or CAD/STP files?

This depends on what was agreed before the development work began. We review the payment record, quotation, emails, development scope, NDA/NNN, and any manufacturing or prototype agreement to determine whether file delivery, ownership, and future use were clearly addressed.

I already shared drawings with a Chinese factory. Is an NNN still useful?

It may still be useful, but the strategy changes. If drawings, samples, CAD files, or technical details have already been shared, an NNN agreement alone cannot erase the disclosure. The next step is to review what was shared, who received it, whether any purchase orders, invoices, emails, samples, or development records exist, and whether a China-side NNN, manufacturing agreement, tooling ownership clause, trademark filing, or file-control terms can still reduce the risk going forward.

Should I sign an NNN agreement or a manufacturing agreement first?

It depends on the stage. Before disclosing product details, drawings, suppliers, pricing, or technical files, a China-focused NNN agreement is often the first protective layer. Once the factory relationship, pricing, samples, tooling, payment path, and production responsibilities become clearer, a manufacturing agreement or supplier agreement may be needed to cover quality, delivery, tooling ownership, file control, improvements, exclusivity, and remedies. A Supplier Control Review helps decide which document should come first.

How do I prevent a sourcing agent from controlling my factory relationship?

The key is to understand who controls factory access, quotations, purchase orders, invoices, samples, tooling, payment path, and communication records. A sourcing agent may be useful, but the buyer should avoid a structure where the agent controls the manufacturer, the Chinese trademark, the molds, technical files, or production relationship. The review identifies whether direct factory rights, non-circumvention language, supplier transparency, trademark filing, or a revised contract structure is needed.

What should I send to a Chinese factory before IP protection is in place?

Send only what is necessary for the current discussion. Before proper China-side protection is in place, avoid sending complete CAD/STP files, final production drawings, tooling files, source files, supplier lists, brand assets, packaging files, or commercially sensitive manufacturing details unless there is a clear protection structure. A safer first step is to define the disclosure stage, file type, supplier role, trademark status, and whether an NNN, manufacturing agreement, tooling clause, or IP filing is needed first.
