Practical Answer - AI Hardware Supplier Control

What Should an AI Hardware Founder Sign Before Prototype Development in China?

Last updated: July 2026

Prototype development is where vague supplier conversations turn into files, code, samples, tooling decisions, and payment leverage.

In short

Before prototype development in China, an AI hardware founder may need a China NNN, supplier-control agreement, prototype or development agreement, file and tooling ownership terms, firmware and cloud access clauses, and a signing and disclosure checklist.

The Direct Answer

Do not rely on a generic NDA alone. Match the agreement to the prototype work: who receives which files, who develops what, who owns outputs, what subcontractors can see, and how the project can be handed off.

The Agreement Stack

A prototype project may begin with a simple supplier conversation, but it can quickly involve CAD files, Gerbers, BOMs, firmware, cloud dashboards, samples, molds, fixtures, and test reports.

The right document stack depends on the stage and risk. A first disclosure may need an NNN. A paid prototype build may need development terms. Tooling or OEM work may need manufacturing and handoff obligations.

Frequently Asked Questions

Is an NDA enough before prototype development in China?

Usually not for AI hardware. Prototype development often needs non-use, non-circumvention, ownership, subcontractor, tooling, firmware, cloud, and handoff terms.

Should I sign before sending CAD or Gerber files?

In many cases, yes. Sensitive CAD, STP, Gerber, BOM, firmware, and test files should be disclosed only after the recipient, use, and return or deletion obligations are clear.

Can one agreement cover everything?

Sometimes one carefully scoped agreement can cover the first stage. More complex prototype-to-OEM paths may need an NNN plus development, tooling, or manufacturing terms.
