AML: EDD for Complex Cross-Border Structures
Updated: Mar 7, 2025
Exploring EDD for complex structures in cross-border trade and international compliance to mitigate risks and ensure transparency in global transactions.
Understanding Complex Structures in Cross-Border Trade and International Compliance

When it comes to cross-border trade, one of the key pillars of compliance is conducting thorough Customer Due Diligence (CDD). This process becomes especially critical when dealing with complex corporate structures. As businesses expand across borders, it’s not uncommon to encounter ownership models that appear convoluted, and while these structures might have legitimate business reasons, they also pose potential risks that need to be understood and mitigated.
In this blog entry, we’ll dive into how to conduct CDD on complex ownership structures and the heightened scrutiny that must be applied in these cases and how to do it.

Let's begin:
The first step in evaluating a complex structure is to establish the rationale behind it.
Understanding the economic purpose of a multi-layered ownership structure is essential.
Not all complex structures are created to evade regulations or financial scrutiny, but it is important to assess whether these arrangements are designed for legitimate business reasons or if they raise concerns related to money laundering, tax evasion, or sanctions violations.
Starting the Process: Ownership Structure Verification
To begin with, obtaining the ownership structure from the customer is crucial. This document should ideally be signed by a senior manager, confirming its accuracy. It’s important to verify this information against reliable sources. Cross-referencing ownership structures ensures that the details provided match those found in public records or other trusted databases, such as company and land registries.
Investigative Tools for CDD
A comprehensive background check on both the customer and any key individuals involved, including beneficial owners and controlling persons, is a critical next step. Various methods and tools are available to verify the identities of individuals and confirm their suitability for business relationships.
One of the key tools in this process is sanctions screening, ensuring that none of the individuals or entities involved are listed on any international sanctions lists.
Additionally, Politically Exposed Persons (PEP) checks are essential to assess whether individuals hold positions that might expose them to higher risk. Adverse media searches also play a significant role in identifying any negative press related to the entities or individuals under investigation.
Verification sources for these checks include both public and private databases.
Publicly available resources, such as company and land registries, provide an initial insight into ownership structures, while private databases, including credit bureaus and commercial databases, offer a deeper dive into the financial health and reputation of the individuals and businesses involved.
Identifying Layers and Ensuring Transparency
One of the most complex aspects of CDD is tracing ownership through multiple layers. Complex corporate structures often involve intermediary entities, nominee shareholders, or trustees, which can obscure the identity of ultimate beneficial owners (UBOs). It is crucial to dig deeper into these layers and uncover the true controlling parties behind the company. Scrutinizing nominee arrangements—whether they involve shareholders, directors, or trustees—is essential. For each of these roles, it’s vital to assess the background, qualifications, and experience of individuals fulfilling these positions. In cases where intermediary entities are involved, it’s necessary to investigate them thoroughly to ensure that their existence is legitimate and not designed to obscure ownership or control. This is particularly relevant in cross-border situations where offshore entities may be used to obscure the true ownership structure.
Special Consideration for Cross-Border Entities
When dealing with cross-border structures, particular attention must be paid to the complexity added by international borders. Companies operating in multiple jurisdictions or through offshore entities often use these mechanisms to benefit from lower regulatory oversight or tax advantages. Here, ongoing monitoring is especially important to ensure that any changes in ownership or control structures are promptly identified and assessed.
Enhanced Due Diligence for High-Risk Cases
In certain cases, the standard CDD process may not be sufficient. Enhanced Due Diligence (EDD) is required when the complexity of a structure, or the nature of the business, presents heightened risks. In these cases, additional layers of scrutiny are required to safeguard against potential violations.
The first step in EDD is to gain a clearer understanding of the purpose behind the business relationship and the nature of expected transactions. This can include asking for more detailed documentation, such as business plans and contracts, which provide further insight into the legitimacy of the business model.
A particularly important element in EDD is the enhanced verification of beneficial ownership. This involves not just confirming the identity of the owners, but also obtaining detailed supporting documents, such as tax returns or inheritance records, to validate the source of their wealth. This is critical in preventing financial crimes such as money laundering or financing terrorism.
An example of where EDD is vital in international trade can be seen in the EU’s sanctions regime against Russia. The EU sanctions target high-risk sectors, including battlefield items like weapons, dual-use goods, and critical technology. Under these sanctions, a heightened level of scrutiny and enhanced due diligence is required to ensure that goods with potential military applications do not reach restricted parties or conflict zones. This means companies involved in trade of such goods must conduct in-depth investigations into the final end users and the beneficial ownership of entities in countries of concern. Failure to implement adequate EDD measures can result in severe legal and financial consequences, as well as damage to a company’s reputation.
Ongoing Monitoring and Third-Party Verification
The EDD process doesn't end once the business relationship is established. Regular monitoring of the account and transactions is essential to ensure that the business continues to operate within the bounds of the law. Enhanced due diligence requires frequent reviews of the ownership structure and transaction activities to detect any irregularities or red flags.
Third-party verification is also an important aspect of EDD. Utilizing external auditors, investigators, or public records can help verify the information provided by customers. These independent investigations ensure that there are no discrepancies between customer-provided data and the information available through other sources.
Senior Management Oversight
For high-risk clients, senior management approval is necessary before entering into or continuing a business relationship. This approval should be based on a thorough assessment of the risks, with detailed reporting to senior management on any findings that could potentially lead to financial, legal, or reputational harm.
Documenting the Process
Finally, throughout the entire CDD and EDD process, it is essential to document all findings, including communications with the customer and any approvals given. This ensures compliance with regulatory requirements and provides an audit trail in the event of an investigation. Additionally, all records should be maintained for the duration required by national laws and filed in a way that complies with privacy regulations.
Conclusion
Navigating complex corporate structures is one of the most challenging aspects of cross-border trade and international compliance. By applying rigorous CDD and EDD practices, businesses can ensure they are not inadvertently exposed to financial or legal risks. Thorough background checks, careful verification of ownership, ongoing monitoring, and senior management oversight are essential to maintaining transparency and compliance. These practices not only safeguard your business but also contribute to maintaining the integrity of the broader global trade ecosystem. As seen with EU sanctions against Russia, the stakes are particularly high when dealing with dual-use or military goods, making enhanced due diligence a critical part of every international trade transaction.
