Freeports and Private Storage

Criminals place high-value assets—such as art, jewelry, precious metals, or other collectibles—in freeports or similarly secure private storage facilities. Often located in jurisdictions with minimal disclosure requirements, these sites enable owners to hide their identities behind shell entities or anonymized registrations. Freeport operations frequently exist in tax-free or lightly regulated zones, providing discrete spaces to store valuables while bypassing standard border or customs checks. Some freeports reportedly hold billions of dollars in stored art, allowing criminals to safeguard illicit wealth with minimal oversight and potentially inflate asset valuations or undertake multiple internal trades. By keeping these assets off public records and outside conventional banking channels, criminals maintain the ability to discreetly transfer, sell, or retrieve them at will, making it more difficult for law enforcement to trace and seize illegal proceeds.

Freeports

Secure Storage

Tactics

ML.TA0010
|
|

Criminals use freeports and private storage to secure high-value illicit assets out of law enforcement's reach, preventing seizure and preserving long-term control of their wealth. The opaque nature of these facilities reduces transparency and hinders investigations, aligning squarely with the goal of safeguarding illicit proceeds post-integration.

Risks

RS0001
|
Customer Risk
|

The technique also relies on criminals hiding behind shell or offshore entities as registered owners of valuables stored in freeports. These opaque ownership structures obscure beneficial owners, thwart KYC processes, and limit investigators' ability to trace the ultimate controllers of illicit assets.

RS0004
|
Jurisdictional Risk
|

Criminals deliberately choose freeports and similar private storage in lightly regulated or tax-free zones that offer minimal AML oversight. By operating in jurisdictions with lax disclosure requirements and weak regulatory frameworks, they can store, transfer, and conceal high-value assets with little to no scrutiny, effectively sheltering illicit proceeds from law enforcement.

Indicators

IND01952
|

Repeated high-value transfers labeled as 'storage fees' or 'facility charges' to freeport or private storage operators, with no corresponding commercial activity or revenue streams.

IND01955
|

Customer declines to provide supporting documentation for the nature or value of assets placed in freeport or private storage, despite incurring significant costs.

IND01958
|

Use of freeport facilities located in jurisdictions that do not require public disclosure of asset ownership or beneficial owners.

IND01960
|

High-value art, jewelry, or collectible assets held through multiple shell companies, all directing payments to the same private storage facility.

IND01962
|

Frequent revisions to ownership or registration details for items kept in freeports, with no clear commercial rationale or change in business operations.

IND01965
|

Abruptly and significantly fluctuating valuations assigned to stored high-value assets in freeport facilities, without credible appraisals or supporting documentation.

IND01967
|

Frequent cross-border shipping of high-value items into or out of freeports without matching or consistent customs or trade documentation.

Data Sources

Aggregates negative news and legal records indicating reported fraud, contested ownership, or suspicious valuations tied to freeport activity. Aids in uncovering prior allegations or legal actions related to high-value asset storage.

Logs declared imports and exports, including valuable goods shipped across borders into or out of freeports. Detects discrepancies between declared items and actual shipments, indicating possible smuggling or unreported asset movements.

Consolidates information on freeport jurisdictions known for secrecy laws or minimal disclosure obligations. Enables risk-based assessment of storage in high-secrecy regions and helps identify cross-border activity where local regulations may hinder standard AML controls.

Contains financial statements, corporate filings, and tax returns, revealing a business’s revenue streams, expenses, and overall financial health. It can confirm the absence of legitimate income supporting significant "storage fees" or inconsistent flows from multiple shell entities to the same private storage facility.

Provides itemized records of all financial transactions, including timestamps, amounts, counterparties, and references (e.g., 'storage fees'). This enables investigators to detect repeated high-value payments to freeport or private storage operators that lack apparent commercial justification, indicating potential layering or placement of illicit funds.

Maintains records and version histories of asset documentation, including appraisal certificates or ownership filings for items stored in freeports. Enables the detection of suspicious alterations, missing records, or inconsistent documentation related to high-value assets.

Includes bills of lading, shipping manifests, and invoices for international shipments. Validates the movement of high-value assets and uncovers missing or inconsistent paperwork for items stored in or transferred through freeports.

Encompasses verified identities, beneficial ownership details, and information regarding customers’ high-value assets or transactions. Highlights instances where clients are unwilling to disclose the nature or valuation of assets for freeport storage, prompting deeper scrutiny into potential illicit use.

Captures registration, transfer, and ownership details of art, jewelry, and other high-value assets. Helps track frequent changes in ownership or inflated valuations for items in freeports, revealing possible manipulation or laundering activity.

Provides official or aggregated data on business entities, including ownership structures, directorships, and registered shareholders. Supports detecting overlapping beneficial owners among multiple shell companies using the same private storage facility.

Mitigations

Conduct advanced background checks and verification for clients dealing with freeports or private storage of high-value assets. This includes verifying provenance, cross-checking declared valuations with independent appraisals, identifying beneficial owners behind shell entities used to hold the assets, and applying ongoing monitoring to detect frequent changes in ownership or abrupt value fluctuations without credible explanation. These enhanced steps address the minimal oversight and anonymity exploited in freeport storage.

Require comprehensive documentation on the nature and source of high-value assets intended for freeport or private storage. Verify the true owner(s) and confirm alignment with the customer’s known wealth and economic profile. By establishing transparency at onboarding and throughout the relationship, institutions mitigate risks associated with anonymous asset holding and the potential disguise of illicit proceeds.

Implement specialized monitoring rules to flag repetitive high-value payments to freeport or private storage operators, especially when these payments are unaccompanied by supporting documentation or commercial justification. Track abrupt increases in such 'facility charges,' cross-verify stored asset details, and escalate when patterns suggest undisclosed beneficial owners or concealed laundering activity.

Corroborate asset ownership claims and valuations by referencing external sources, including public databases, stolen property registries, reputable auction house records, and art market intelligence. Investigate beneficial ownership structures for ties to high-risk jurisdictions or shell entities. This measure reveals hidden links and helps detect illicitly acquired items parked in freeports under minimal disclosure requirements.

Restrict or refuse services related to freeport storage if a client fails to provide credible information on an asset’s origin, ownership, or valuation. This may include suspending payments to the facility or freezing accounts until thorough verification is completed. By withholding services under opaque conditions, institutions minimize exposure to hidden, high-value assets of questionable legitimacy.

Systematically scrutinize trade and shipping records for high-value items entering or exiting freeports, confirming that declared valuations, shipping routes, and counterparties align with legitimate commercial purposes. Detect misinvoicing, multiple internal trades with no valid business rationale, and suspicious cross-border movements intended to mask ownership or inflate asset values beyond regulatory oversight.

Instruments

|
  • High-value jewelry is stored in freeport vaults, where the record-keeping requirements imposed by operators are often lax.
  • Shell or offshore entities pay storage fees and officially register as owners, concealing the jewelry’s true beneficiary.
  • The small, portable nature of jewelry makes it easy to transport or sell without drawing attention, facilitating hidden transfers of illicit wealth.
  • Criminals place high-value metals (e.g., gold, platinum) and gemstones (e.g., diamonds) into freeports under opaque corporate structures, shielding their identities from authorities.
  • Freeports’ minimal disclosure requirements help conceal both beneficial owners and the true origin of the assets.
  • Once stored, these items can be privately sold, traded, or physically transferred across borders without triggering standard customs checks or reporting, facilitating further layering of illicit funds.
  • Artworks and collectibles are often stored in private facilities with limited transparency, enabling criminals to remain anonymous or use shell companies as registered owners.
  • The subjective and frequently fluctuating valuations of art facilitate the justification of large financial movements through reappraisal or manipulation of declared worth.
  • Internal trades and silent ownership changes in freeports further obscure the provenance and trail of funds linked to these assets.

Actors

These providers enable criminals to form and maintain corporate or foundation structures that underpin freeport storage by:

  • Incorporating and administering shell or offshore companies that hold high-value assets.
  • Arranging nominee directors or shareholders to create additional layers of anonymity.
  • Managing payment and document filings for storage fees, further complicating financial institutions’ due diligence efforts.

Illicit operators utilize freeports and private storage to conceal criminal proceeds by:

  • Placing high-value assets (art, jewelry, precious metals) in secure facilities with minimal disclosure requirements.
  • Bypassing standard customs or border checks and maintaining anonymity through shell or offshore registrations.
  • Retaining the ability to discreetly transfer or retrieve valuables, reducing transparency for financial institutions attempting to trace illicit funds.

Art dealers, auction houses, and custodians can be exploited by criminals storing or trading art in freeports through:

  • Inflating or manipulating asset valuations with limited transparent recordkeeping.
  • Granting frequent changes to ownership or registrations, obscuring beneficial owners from financial institutions.
  • Permitting discreet acquisitions or disposals of high-value pieces, complicating efforts to trace or seize illicit assets.

These entities, including offshore companies (ID 256) and private interest foundations (ID 278), obscure the beneficial ownership of freeport-stored assets by:

  • Registering high-value items under corporate names or foundation structures, thereby masking the true owners.
  • Conducting internal trades and paying storage fees under layered corporate identities, which limits financial institutions’ visibility.
  • Facilitating anonymized transactions across multiple jurisdictions, thus hindering the detection of illicit origins.
