A logistics director at a mid-sized trading house opens her inbox to find a letter from OFAC. The company is on the SDN List (OFAC's list of Specially Designated Nationals and blocked persons). US-dollar transactions have frozen. Correspondent banks are declining. The business has weeks – perhaps days – before the operational damage becomes irreversible. The question is not whether to pursue delisting. The question is how to build a case that can actually succeed.
Building the delisting evidence package under OFAC is the central task in any reconsideration petition. The package must address the legal basis for designation under IEEPA or the relevant programme authority, challenge the factual predicate OFAC relied upon, and demonstrate – with contemporaneous documents rather than assertions – that the grounds for designation no longer apply or never did. As of February 2026, OFAC continues to operate an administrative reconsideration process alongside the federal judicial-review route, and the evidence package you submit determines which of those paths is viable.
This guide walks through each stage of building that package, identifies where petitions most commonly fail, and explains how the OFAC process differs from the comparable procedures under OFSI, the EU General Court, and other regimes your counterparties or investors may also need to consider.
Step 1: Understand the legal basis and identify the designation grounds
Before a single document is gathered, the petitioner must know precisely what ground OFAC used to list the party – because the evidence package must answer that specific ground, not a general theory of innocence.
OFAC designations under IEEPA are made pursuant to programme-specific executive orders and the regulations that implement them. Each programme identifies categories of designable conduct: acting for or on behalf of a blocked party, providing material support, being owned or controlled by a designated person, or meeting a programme-specific criterion. The designation notice gives a condensed public statement of reasons. That statement is the first document to dissect.
In our experience, petitioners who skip this step assemble evidence that rebuts conduct OFAC did not allege. That wastes the reconsideration window. Map each phrase in the designation statement to a legal element. Identify which elements are factual (where documents and witnesses help) and which are legal (where the argument turns on the proper interpretation of the authority). That mapping becomes the skeleton of the entire package.
A cross-border dimension can complicate this immediately. If the same client is also listed under an EU Council regulation or by OFSI, the designation grounds may differ between regimes. OFAC's legal basis is not automatically the same as the EU Council's basis, and the evidentiary standards are not identical. We regularly advise clients whose primary priority is OFAC delisting but who face EU and UK listings built on partially different factual predicates. The evidence assembled for OFAC will often need adaptation before it serves the EU or UK process.
Step 2: Obtain and organise the administrative record
Once you have mapped the designation grounds, the next step is to obtain every document that touches the factual predicate – starting with the official record and working outward.
Under IEEPA and OFAC's administrative practice, a designated party may request the administrative record through the applicable legal channels, including a Freedom of Information Act request or through litigation discovery in a judicial-review proceeding. The completeness of what OFAC releases can vary; some material may be withheld on national-security grounds. That is not a reason to wait. Work with what is available and build the evidentiary case in parallel.
The organising principle is simple: every factual assertion in the designation record must be paired with the best available documentary answer. That means:
- Corporate records – ownership charts, shareholder registers, constitutional documents – to address any control or ownership allegation.
- Financial records – bank statements, ledgers, wire-transfer logs – to address any payment or transaction allegation.
- Contracts and correspondence – to address any relationship-with-a-blocked-person allegation.
- Regulatory filings – licences, customs declarations, tax returns – to address any trade or licensing allegation.
Document organisation matters as much as document content. A package that forces OFAC's reviewing analysts to hunt for the answer to a specific allegation is less persuasive than one structured to mirror the designation grounds sequentially. Use a clear cross-reference index. Number exhibits. State plainly what each exhibit demonstrates and how it responds to the relevant ground.
This is the stage at which local counsel in the relevant jurisdiction may be needed. Obtaining records held abroad – in a corporate registry, a bank, or a government archive – can require legal action or regulatory clearance in the country where those records sit. Build time for that into the project plan.
Step 3: Commission and structure the legal analysis
The documentary evidence does not speak for itself. It requires a legal analysis that translates the documents into a coherent argument addressing each designation ground.
The legal analysis in the evidence package performs several functions. First, it sets out the governing authority: the programme, the executive order, and the regulatory definitions that determine whether the alleged conduct actually meets the threshold for designation. Second, it applies those definitions to the documents assembled in Step 2. Third, it anticipates OFAC's likely counter-argument and addresses it before OFAC raises it.
Do not structure the analysis as a general character statement ("this is a law-abiding company"). Structure it as a ground-by-ground rebuttal. If the designation alleges ownership or control by a blocked person, address the ownership and control (the OFAC test for whether a non-listed entity is captured through a listed person) question with the corporate documents, demonstrate that the 50 percent or more threshold is not met, and show – if relevant – that no practical control exists either. If the designation alleges a transaction with a blocked party, address the transaction specifically, with the documentary record, and then address whether the transaction, even if it occurred, actually satisfied the legal criterion for designation.
One common error at this stage is conflating the administrative reconsideration standard with the judicial-review standard. The administrative petition is addressed to OFAC itself. It should engage with the agency's prior factual findings and give the agency a clear, documented basis to reverse or modify the designation. The judicial-review petition is addressed to a federal court and raises legal challenges to the agency's decision. Both require evidence, but the emphasis differs. Preparing the wrong document for the wrong forum is a recoverable mistake – but only if caught early.
How does the OFAC reconsideration process compare with OFSI, the EU General Court, and other regimes?
The OFAC administrative reconsideration process is practitioner-facing and document-intensive, but it differs meaningfully from its counterparts under OFSI, the EU, and the UN – and those differences have direct consequences for how the evidence package is built.
Under OFSI, the UK financial sanctions authority, a designated person may seek a review by OFSI itself and, if unsuccessful, may appeal to the Upper Tribunal. The evidentiary standard in the Upper Tribunal differs from the OFAC process: it is a judicial forum with formal rules of evidence and an independent decision-maker. The OFAC administrative process, by contrast, puts the initial review decision with the same agency that made the designation. That is not unique to OFAC – OFSI's internal review has the same structure – but it means the administrative package must be built to a standard that anticipates, and ideally forecloses, the need for judicial review.
Before the EU General Court, an annulment action challenges the Council's designation decision on grounds of procedural illegality, manifest error of assessment, or violation of fundamental rights. The EU process is litigation from the outset, not an administrative petition. The documents assembled for OFAC reconsideration will often be relevant, but the legal framing is different: EU General Court pleadings must address EU procedural law, the standard of review under EU administrative law, and the Council's stated reasons in the Council Decision and implementing regulation.
For clients with listings in multiple jurisdictions, we build the evidence package in layers: a core factual record that is regime-agnostic, with regime-specific legal analyses layered on top. That avoids assembling four separate document sets while ensuring each submission addresses the forum's specific legal requirements. Have you mapped all active designations before deciding which to challenge first? The sequencing matters: a successful OFAC delisting can affect the political dynamics of a parallel EU or UK challenge, but it does not automatically produce delisting in either of those regimes.
For clients with exposure in Australia, the comparable process operates through a distinct administrative channel. Our colleagues who advise on that regime can assist with the delisting evidence package process under the Australian Autonomous Sanctions regime. The process under OFSI is addressed in detail in our OFSI delisting evidence package guide. For Switzerland, see our SECO delisting evidence package guide.
Step 4: Address secondary sanctions risk and third-party exposure
An OFAC-listed party's evidence package must address not only its own primary exposure but the downstream secondary-sanctions risk that the designation has created for its counterparties – because those counterparties' behaviour during the listing period will itself become relevant to the reconsideration.
Secondary sanctions (prohibitions that apply to non-US persons who engage in certain conduct with designated parties, even where no US nexus would otherwise bring them within OFAC's primary jurisdiction) can cause counterparties to cease dealing with the designated party. That de-risking (a financial institution or trading partner exiting a relationship to avoid sanctions exposure) affects the designated party's operations and its ability to gather documents held by those counterparties. It also means that the counterparties themselves may have reporting obligations or compliance concerns that prevent full co-operation with an evidence-gathering exercise.
Address this practically. Identify which counterparties hold documents relevant to the rebuttal. Determine whether they can provide those documents under the applicable legal regime, including whether any authorisation or licence is needed for the exchange of information with a blocked person. If a general licence permits certain information-sharing for legal proceedings, obtain and cite it in the cover letter to any such communication. Do not assume co-operation will be freely given; build the legal basis for it.
The package should also address the period between the designation date and the petition date. OFAC's reviewing analysts will scrutinise whether the designated party took any steps during that period inconsistent with the delisting petition. A company that continued trading with blocked parties after designation, even under claimed necessity, will face a harder reconsideration process. The package must either demonstrate that no such conduct occurred or explain – with documents and a legal analysis – why any such conduct was authorised or excusable.
Step 5: Prepare the formal submission and manage the process
The formal submission to OFAC is not simply the documents assembled in prior steps. It is a structured legal communication addressed to a regulatory body that makes consequential administrative decisions.
The cover letter is critical. It should open with a concise statement of the petition: who the petitioner is, what designation is challenged, and what relief is sought. It should then provide a roadmap to the evidence package, cross-referencing the designation grounds to the exhibits and legal analysis that rebut each ground. A well-written cover letter allows OFAC's reviewing attorneys to read the package efficiently. A poor cover letter forces them to construct the petitioner's argument themselves – and they will not construct it in the petitioner's favour.
The submission must be complete on filing. OFAC is not required to invite supplemental submissions, and a petition that leaves gaps invites denial. If documents are unavailable at the time of filing – because they are held by a third party, in a foreign registry, or are the subject of ongoing legal proceedings – explain that in the cover letter, state what steps are being taken to obtain them, and provide a realistic timeline. Silence on a gap is more damaging than an explanation.
After submission, the administrative process does not operate on a published timetable. Reconsideration petitions can take a significant period to resolve. During that period, the designated party should maintain regular contact with its counsel, continue gathering any outstanding documents, and monitor for regulatory developments that might affect the designation. OFAC sometimes updates its designation basis in response to changed circumstances. If the programme under which the designation was made is modified or a new executive order is issued that bears on the designation grounds, the petition may need to be supplemented.
The position above covers the standard administrative route. Your facts – the programme, the designation grounds, the counterparties affected, the jurisdictions where documents are held – will shape the analysis and the sequencing.

Risk flags: when does an OFAC reconsideration petition face the greatest difficulty?
Not every petition succeeds. The evidentiary and legal burden on the petitioner is real, and certain fact patterns make reconsideration demonsturably harder.
The most significant risk flag is a designation based on national-security intelligence that OFAC is not prepared to disclose. Where the publicly available designation statement contains minimal factual detail, the petitioner faces an asymmetric evidentiary problem: rebutting allegations that are not fully stated. In that situation, the petition strategy shifts – from pure factual rebuttal toward legal argument about the procedural adequacy of the designation and the standard of proof that OFAC must meet. That is a harder path but it is a legitimate one.
A second risk flag is an ownership or control structure that is genuinely complex. If the corporate chain between the petitioner and a blocked person involves multiple layers of ownership across several jurisdictions, OFAC may apply the 50 percent rule (OFAC's rule treating entities owned 50 percent or more by blocked persons as themselves blocked) in ways that are contested at the margins. The petitioner must model every possible aggregation of blocked-person ownership and demonstrate that none reaches the threshold – or, where it does, argue that the threshold applies only to direct economic ownership and that the relevant held interest is different in character.
A third flag is the passage of time since designation. A long-standing designation is not harder to challenge on the merits, but the volume of secondary commercial consequences that have accumulated increases the complexity of the submission. Every transaction the designated party has entered into since listing, every correspondent relationship that has lapsed, every third-party communication that refers to the designation – all of it may be relevant.
There is a common myth worth addressing here. Many clients initially believe that a successful OFAC administrative reconsideration petition will automatically result in removal from all other lists – EU, UN, UK, Australian. It will not. OFAC delisting is OFAC-specific. The UN Consolidated List, the EU listings maintained under the relevant Council regulations, and the OFSI designations are all independent and each requires its own process. An OFAC delisting can be a useful piece of evidence in a parallel EU or UK proceeding, but it carries no binding force in those fora. If you are building a multi-regime delisting strategy, sequence carefully and treat each regime as a distinct legal problem.
If a petition has already been submitted and received an adverse response, or if the administrative process has stalled, the judicial-review route may need to be considered in parallel. An early review of that option preserves choices that narrow the longer the matter runs. Contact us at info@caldervance.com to discuss your situation confidentially.
A practical example: the multi-layered ownership petition
In a recent matter, a trading business in the commodities sector was designated under the applicable country programme on the basis that it was owned or controlled by a blocked party. The public designation statement gave no detail beyond the name of the alleged blocked-party controller.
We were instructed to build the reconsideration evidence package. The first step was to obtain the corporate record from four different registries across three jurisdictions. That process took several weeks and required engagement with local counsel in two of the registries' countries. The documents revealed a chain of intermediate holding companies, none of which was itself designated, with no single blocked person holding an interest that, individually, reached the 50 percent or more threshold.
The critical question was aggregation: whether the combined interests of two individuals, one of whom was a programme-designated person and the other of whom was related to a second designated person but not personally listed, could be aggregated to reach the threshold. We prepared a detailed legal analysis of the aggregation principles under IEEPA and the applicable programme guidance. The analysis concluded that one of the two individuals was not a blocked person for programme purposes and that his interest could not be aggregated with the listed individual's holding. The combined documented holding of the single blocked person fell below the threshold.
The package was submitted with a structured cover letter, eighteen numbered exhibits, and a legal memorandum addressing each ground. The matter was resolved administratively. No outcome is guaranteed in any future matter; this example is provided to illustrate the practical work involved.
