Sending Data to AI Services Abroad: EU Business Using US Cloud AI

Why This Matters

If your EU business sends data to a US-based AI service like OpenAI or Google, you need Standard Contractual Clauses and a transfer impact assessment. Every time data crosses a border on its way to an AI service, data transfer rules kick in. These rules exist because different countries protect personal data at different levels, and governments want to make sure their residents' data stays protected even when it leaves the country.

For businesses, this creates a real compliance challenge. Most AI tools are cloud-based, and the cloud does not respect national borders. Your data may travel through multiple countries before reaching the AI system that processes it, and each border crossing can trigger additional legal requirements.

The Legal Framework

Data transfer rules vary by country, but most follow a similar pattern. First, you need a legal basis for the transfer itself — this is separate from your legal basis for processing the data in the first place. Second, you must ensure the receiving country or organisation provides adequate data protection. Third, you need to document everything.

In the EU, GDPR Chapter V sets the gold standard for transfer rules. Transfers to countries with an adequacy decision are straightforward. Transfers to other countries require Standard Contractual Clauses (SCCs), Binding Corporate Rules (BCRs), or another approved mechanism. And since Schrems II, you also need a Transfer Impact Assessment.

Other countries have their own versions of these rules. Japan's APPI, Brazil's LGPD, South Korea's PIPA, and Singapore's PDPA all restrict international data transfers, though the specific mechanisms differ.

What Most Businesses Get Wrong

The biggest mistake is not realising that using a cloud AI service counts as an international data transfer. When you paste customer data into an AI chatbot, upload files to an AI analysis tool, or connect your CRM to an AI service, the data goes somewhere. If that somewhere is another country, transfer rules apply.

Another common error is relying solely on your AI vendor's assurances. Your vendor may claim compliance, but under most data protection laws, you — the data controller — bear ultimate responsibility. You need to verify your vendor's claims, not just accept them.

Many businesses also forget about onward transfers. Your AI vendor may send data to their own sub-processors in additional countries. Each onward transfer needs its own legal basis, and you need to know about and approve each one.

Practical Steps

First, map your data flows. For each AI tool you use, document what data goes in, where it is processed, and who has access. Ask your vendors for this information in writing.

Second, put the right legal mechanisms in place. This usually means Standard Contractual Clauses for EU transfers, and equivalent mechanisms for other jurisdictions. Your vendor should be able to provide these.

Third, conduct a Transfer Impact Assessment. Evaluate whether the destination country's laws could allow government access to your data that would undermine the protections you have put in place. If so, you may need additional technical safeguards like encryption.

Fourth, keep records. Document your assessment, the safeguards you have chosen, and why you believe the transfer is lawful. If a regulator asks, you need to show your work.
