Cross-Border Data Transfers – Legal Challenges for Global Companies

Moving data across borders sounds straightforward. In practice, it is one of the most legally complex things a global company can do. 

Every time a U.S. company sends customer data to an overseas vendor, stores it on foreign servers, or allows an international team member to access it remotely, a cross-border data transfer has occurred. 

And depending on where that data originated, multiple privacy laws may apply simultaneously. According to the United Nations Conference on Trade and Development, 71% of countries now have data privacy legislation in place. 

That number keeps growing. For global companies, that means more jurisdictions, more rules, and more ways to get it wrong. 

Not All Countries Treat Data Transfers The Same Way. 

The core challenge is that privacy laws do not align across borders. The EU treats personal data as a fundamental right. The U.S. approaches it more through sector-specific regulation. 

Countries like China and Russia have data localization laws that require certain data to stay within national borders entirely. What is legally acceptable in one country can be a direct violation in another. 

A U.S. company transferring EU customer data to an American cloud provider, for example, may be violating GDPR, even if everything about the transfer is routine from a U.S. law perspective. 

Data Localization Laws Are Forcing Companies To Rethink Infrastructure. 

Some countries do not just regulate how data is transferred; they prohibit it from leaving at all. Russia’s Federal Law No. 242-FZ requires personal data of Russian citizens to be stored on servers physically located in Russia. 

China’s Personal Information Protection Law (PIPL) has similar requirements for certain categories of data. For global companies, this creates real operational friction: 

• You may need separate data storage systems for different markets. 
• A single global CRM or HR platform may not be legally usable in every country. 
• Vendor contracts need to reflect local storage requirements. 

This is not a future problem. Companies operating in these markets are managing it right now. 

The EU Remains The Strictest Jurisdiction For Outbound Transfers. 

Under GDPR, transferring personal data outside the European Economic Area (EEA) is only permitted when the destination country provides an “adequate” level of data protection, or when a specific legal mechanism is in place. 

The main transfer tools available to global companies include: 

The DPF replaced the invalidated Privacy Shield in 2023, but it faces ongoing legal scrutiny. Companies relying solely on it should have a backup mechanism in place. 

Regulators Are Actively Enforcing Cross-Border Transfer Violations. 

This is not a theoretical risk. In 2023, Meta was fined $1.3 billion, the largest GDPR fine in history, specifically for transferring EU user data to U.S. servers without adequate protection. 

LinkedIn, TikTok, and several U.S. analytics companies have faced similar actions. The Irish Data Protection Commission, which oversees many U.S. tech companies’ EU operations, issued over €1.7 billion in fines between 2021 and 2023 alone. 

A Transfer Impact Assessment Helps Identify Legal Exposure. 

Before transferring data internationally, companies should conduct a Transfer Impact Assessment (TIA). This documents the following: 

• What data is being transferred and to where? 
• What legal mechanism justifies the transfer? 
• Whether the destination country’s laws undermine the protections in place. 

It is not a guarantee of compliance, but it demonstrates due diligence, which matters significantly if a regulator comes knocking.
