International transfers of personal data require robust adequacy mechanisms, and companies that ignore this requirement face severe sanctions from the ANPD (Brazil’s National Data Protection Authority) and significant reputational risks.

The Current Landscape of International Data Transfers

We live in a globalized digital economy where the cross-border flow of personal data has gone from exception to rule. Brazilian companies use cloud servers hosted in the United States, hire software vendors in Europe, run technical support operations in India, and process payments through gateways based in multiple jurisdictions. Against this backdrop, this article examines how Brazil’s General Data Protection Law (LGPD) regulates these transfers and which adequacy mechanisms are available to ensure legal compliance.

Choosing an adequacy mechanism for international data transfers is not just a legal decision. It is a strategic one that directly affects an organization’s operations, reputation, and competitiveness in the global market.

Articles 33 through 36 of the LGPD set out the circumstances in which international transfers of personal data are permitted. Brazilian lawmakers recognized that banning cross-border flows altogether would be unworkable and harmful to the economy. They also understood that allowing unrestricted transfers would put data subjects’ fundamental rights at risk. The solution was a system of authorizations built on mechanisms verified as consistent with international standards of protection.

The National Data Protection Authority (ANPD) plays a central role in this ecosystem. It assesses the level of data protection in other countries and international organizations, approves specific contractual clauses, and issues supplementary rules on the subject. As the LGPD’s regulations have developed, the ANPD has made progress in creating instruments that give greater legal certainty to organizations that need to make international transfers.

Adequacy Mechanisms Under the LGPD

Article 33 of the LGPD lists the circumstances that authorize international transfers of personal data. Each mechanism has its own characteristics and specific requirements, which we examine below in the detail needed for a practical understanding.

ANPD Adequacy Decision

The first mechanism is a transfer to countries or international organizations that provide a level of personal data protection adequate to that required by Brazilian law. Only the ANPD may make this assessment. It must consider the destination country’s general and sector-specific rules, the nature of the data, whether an independent supervisory authority exists, and the international commitments the receiving country has undertaken. This model follows the approach of the European Union’s General Data Protection Regulation (GDPR), under which the European Commission issues adequacy decisions for third countries.

Specific Contractual Clauses and Standard Clauses

Where there is no adequacy decision, organizations can turn to contractual instruments. The LGPD provides for both specific contractual clauses drafted for a particular transfer and standard contractual clauses approved by the ANPD. These clauses must contain guarantees that the principles, the data subject’s rights, and the data protection regime set out in Brazilian law will be observed. In practice, we find that this is the mechanism most often used by mid-sized and large companies with business relationships with partners in jurisdictions that have no adequacy decision.

Global Corporate Rules (Binding Corporate Rules)

For multinational corporate groups, global corporate rules are a relevant alternative. These are internal data protection policies, approved by the ANPD, that bind every entity in the corporate group regardless of where it is located. This instrument demands a high level of corporate governance, including internal audit mechanisms, employee training, and complaint channels for data subjects.

The Data Subject’s Specific and Prominent Consent

The data subject’s consent also authorizes an international transfer when it is specific and prominent. That said, this mechanism has significant practical limitations. The data subject must be informed in advance that the transfer is international, with the risks involved clearly highlighted. In addition, consent can be withdrawn at any time, which creates operational uncertainty for organizations that depend on continuous data flows.

Other Legal Grounds

The LGPD also provides for additional grounds: compliance with a legal or regulatory obligation, performance of a contract or preliminary procedures, regular exercise of rights in judicial proceedings, protection of the life or physical safety of the data subject or a third party, and ANPD authorization when it finds adequate safeguards. Each of these grounds has its own requirements and must be assessed case by case, taking into account the specific circumstances of the intended transfer.

Due Diligence in International Data Transfers

Before starting any international transfer, we consider careful due diligence essential. This advance review has several dimensions, which must be assessed together to ensure that the transfer meets legal requirements and minimizes risk for both the organization and the data subjects.

Mapping the Data Flow

The first step is to identify precisely which personal data will be transferred, for what purpose, who the recipient will be, in which jurisdiction the recipient is located, and by what means the transfer will take place. This mapping must cover not only direct, intentional transfers but also indirect flows, such as those that occur when cloud computing services replicate data between data centers in different countries.

Assessing the Destination Country’s Level of Protection

Next, you examine the legal framework of the receiving country. You check whether it has data protection legislation equivalent to the LGPD, whether an independent supervisory authority exists, whether effective enforcement mechanisms are in place, and whether the country takes part in relevant international privacy and data protection agreements. Laws that authorize mass government access to personal data (such as state surveillance programs) are a risk factor that must be weighed.

Analyzing the Data Recipient

Beyond the legal context of the destination country, we evaluate the data recipient itself. This means reviewing its information security practices, its privacy policy, its history of security incidents, its certifications (such as ISO 27001 or SOC 2), and its ability to respond to requests from data subjects. Organizations that show maturity in data governance offer greater security for international transfers.

Impact Assessment (Transfer Impact Assessment)

Drawing on the European model developed after the “Schrems II” decision of the Court of Justice of the European Union, we recommend preparing a specific impact assessment for each significant international transfer. This document formalizes the analysis performed and records the risks identified and the supplementary measures adopted to mitigate them. Although the ANPD does not yet expressly require it, this practice is a strong demonstration of accountability and good faith on the part of the controller.

Supplementary Measures and Best Practices

When the due diligence analysis shows that the chosen adequacy mechanism is not, on its own, enough to ensure a level of protection equivalent to that of the LGPD, supplementary measures become necessary. These measures can be technical, contractual, or organizational, and which ones you choose depends on the specific risks identified.

On the technical side, key measures include encryption of data in transit and at rest with keys controlled exclusively by the exporter; pseudonymization that prevents the importer from re-identifying individuals without additional information; data segmentation (transferring only what is strictly necessary for the purpose); and granular access controls. These measures are especially relevant when data is transferred to jurisdictions whose legal framework has identifiable shortcomings.

On the contractual side, we recommend clauses that require the importer to notify the exporter immediately of any government request for access to the data, prohibit onward transfers without prior authorization, establish audit obligations, and provide dispute resolution mechanisms that data subjects can access. Drafting these clauses requires attention to the local law of the destination country to ensure they are enforceable.

On the organizational side, we include designating people responsible for governing international transfers, implementing ongoing training programs, conducting periodic audits of data importers, and keeping detailed records of every transfer made. This organizational structure ensures that adequacy mechanisms do not remain on paper but are actually put into practice in the organization’s daily operations.

Regulatory Outlook and Practical Recommendations

The regulatory landscape for international data transfers is constantly evolving. In Brazil, we are waiting for the ANPD to publish specific regulations on standard contractual clauses, global corporate rules, and the criteria for adequacy decisions. Internationally, we see a growing trend toward cooperation among data protection authorities, with the development of multilateral frameworks that seek to ease cross-border flows without compromising the protection of data subjects.

Organizations that carry out or plan to carry out international data transfers should adopt several essential practices right away. First, conduct a complete inventory of all existing international transfers, including those made through cloud services and SaaS tools. Second, select the most appropriate adequacy mechanism for each data flow and document your analysis. Third, implement supplementary measures proportionate to the risks identified. Fourth, establish a periodic review process, bearing in mind that changes in the destination country’s laws can affect the validity of the transfer. Fifth, keep detailed records showing the organization’s compliance with the LGPD.

Protecting personal data in cross-border contexts is a challenge that calls for a multidisciplinary approach, combining legal, technical, and organizational expertise. Organizations that invest in robust adequacy mechanisms do more than meet their legal obligations. They also build trust with their customers, partners, and regulators, positioning themselves competitively in a market that is increasingly attentive to privacy and the security of personal data.
