AI in manufacturing — technical secrets and export control
For manufacturers the central question is whether technical documents, drawings, patent material and supply chain data can go into an AI system at all. Export control, the separation between factory and office IT, and sharing with overseas sites all shape the answer. This guide sets out how to weight those constraints.

What makes this sector different
Technical documents, drawings and patent material
Trade secrets and pre-filing technical information become a leak risk the moment they could enter a training set. A contractual zero data retention position is the precondition, not a nice-to-have.
Export control and deemed export
Sending technical information to overseas servers can constitute a deemed export under the Foreign Exchange and Foreign Trade Act. Internal rules aligned with METI guidance need to exist before tools are rolled out.
Separating factory (OT) and office (IT) systems
Production systems carry different security requirements, so AI deployment is usually scoped to office functions. Connecting to OT is normally a separate project with purpose-built tooling.
Overseas sites and suppliers
Multilingual support and local legal compliance affect tool selection. A tool standardised at Japanese headquarters is not always usable at an overseas site.
Rules that apply
- Foreign Exchange Act — deemed export
- Transmitting technical information abroad can fall under export control
- Trade secret management (Unfair Competition Prevention Act)
- Whether your handling of technical information still satisfies the secrecy requirement
- ISO 27001
- Increasingly requested within manufacturing supply chains
- TISAX (automotive supply chain)
- Information security requirements for German automotive customers

Questions we get
- Can we summarise or translate technical documents with AI?
- With a contract that excludes your input from training and keeps data in an acceptable jurisdiction, generally yes for internal documents. Pre-filing patent material and anything subject to export control needs a specific internal rule before it goes anywhere near a cloud tool.
- Can AI be used on the factory floor?
- Rarely through these tools. Production systems sit behind a different security boundary; office deployment first, OT as a separate project with purpose-built solutions, is the normal sequence.
- Should overseas sites use the same tool?
- Where possible, yes — a single tool simplifies governance. Check availability and local legal requirements per country first; some tools are unavailable or restricted in specific jurisdictions.
- Can we use AI for supplier communication?
- Translation and summarisation of supplier correspondence is a common early use. Treat anything containing drawings or specifications as technical information subject to the same rules as internal documents.
