A manufacturing group learns on a Monday morning that one of its subsidiaries has appeared on the SDN List (OFAC's list of Specially Designated Nationals and blocked persons). By noon, correspondent banks have frozen accounts. Customers are refusing to transfer funds. Suppliers are citing force majeure. The designation is wrong – or so the business believes. What happens next?
An OFAC reconsideration request is the formal administrative mechanism through which a designated person or entity asks the US Treasury's Office of Foreign Assets Control to review and remove a designation from the SDN List. The process is governed by OFAC's regulations under the International Emergency Economic Powers Act ("IEEPA") and related authorities. As of early 2026, the reconsideration route remains the primary first-instance avenue for US designations, and the quality of the submission – not merely its existence – determines whether a delisting follows.
This guide walks through the procedure step by step, identifies the points at which a submission most commonly fails, compares the US approach with the parallel routes available under OFSI, the EU Council, and the UN, and explains when to involve sanctions counsel before the window narrows.
Step 1: Understand what a reconsideration request actually is – and what it is not
A reconsideration request is an administrative petition to OFAC, asking the agency to reverse or modify a designation on factual or legal grounds. It is not a court challenge, not a licensing application, and not an informal complaint. OFAC reviews the submission internally; there is no hearing, no cross-examination, and no guaranteed timeline. The agency may grant, deny, or simply not respond within any fixed window.
This matters because many businesses confuse reconsideration with two adjacent procedures. First, a specific licence (a case-by-case authorisation to conduct an otherwise prohibited transaction) unblocks one transaction but leaves the designation intact. Second, judicial review in the US federal courts is a distinct route that runs in parallel and requires a separate legal strategy. A reconsideration submission and a court action are not mutually exclusive, but each carries different timelines and burdens.
In our experience, the most consequential error at this stage is treating a reconsideration request as a formality – a letter asserting that the designation is wrong. OFAC treats the submission as an evidentiary record. Every factual claim must be documented. Every legal argument must be grounded in the applicable authority. A thin submission can harden OFAC's position rather than shift it.
Step 2: Assess the basis for the designation before drafting a word
Before a single sentence is written, the factual and legal basis for the designation must be mapped in detail. OFAC publishes, at minimum, the legal authority and a summary basis for each designation. That published record is the starting point, not the finishing point.
The key questions at this stage are: What authority did OFAC invoke? What criterion was asserted – ownership of a blocked person, material support, acting on behalf of a designated party, or something else? What evidence, if any, has OFAC cited? Is the designated entity actually the client, or is there a name-match or identification error?
Identification errors are more common than many assume. A mistaken date of birth, a transliterated name, or a shared address can produce a designation against the wrong person. Where the issue is a factual error of this kind, the evidentiary task is straightforward: demonstrate the mismatch with documentary proof of identity. Where the designation is based on an asserted relationship to another blocked party – the 50 percent rule (OFAC's rule treating entities owned 50 percent or more by blocked persons as themselves blocked) or a material-support finding – the evidentiary task is substantially harder and requires a structured analysis of the ownership and relationship chain.
The position above covers the standard case. Your facts – the counterparty, the ownership structure, the regime in play, the sector – change the analysis materially.

Step 3: Build the evidence package systematically
The evidence package is the core of the submission. OFAC does not give a designated party the opportunity to present evidence in person. What the agency receives in writing is what it considers. A well-constructed package does three things: it tells a coherent narrative, it anticipates the likely grounds for OFAC's decision, and it presents documentary proof for every factual claim.
Practitioners structuring a reconsideration package typically work through the following sequence.
- Identity documentation. Corporate registration documents, beneficial-ownership registers, passports or identity documents for named individuals. These establish who the designated party actually is and rebut any identification error.
- Ownership and control analysis. A complete ownership chart, certified or notarised where available, tracing every layer from the designated entity to its ultimate beneficial owners. Where an entity sits below the 50 percent aggregated-ownership threshold, the analysis must show each holding precisely.
- Evidence rebutting the designation criterion. If OFAC asserted material support, evidence that the relevant transactions were ordinary commercial dealings at arm's length. If OFAC alleged acting-on-behalf-of, evidence of independent decision-making. This section is the most legally demanding part of the package.
- Financial and commercial records. Bank statements, contracts, invoices, and board minutes that corroborate the narrative. Gaps in documentation are exploited on review; collect records proactively.
- Third-party evidence. Declarations from counterparties, audited accounts, legal opinions on foreign-law questions – whatever corroborates the core factual claims.
The package should be accompanied by a legal memorandum that sets out the applicable standard, maps the factual record to each designated criterion, and identifies precisely why the designation should not stand. The memorandum is not a cover letter. It is the analytical backbone of the submission.
Step 4: Submit the reconsideration request and manage the process
Submission is made directly to OFAC's Office of Global Targeting and Designations or the relevant programme office. The submission should be comprehensive from the outset. OFAC is not obliged to invite supplemental submissions, though the agency may do so in practice.
Once submitted, the practical questions are: What is happening in the interim? Can the designated party transact at all while the review is pending? The answer, in most cases, is no – the designation remains in full force unless and until OFAC acts. This makes the interim period operationally critical. A specific licence may authorise limited transactions – for instance, to pay legal fees or to wind down existing contracts – but each licence request is a separate application with its own assessment.
OFAC does not publish fixed review timelines. The process can take months; in contested or complex matters it can take considerably longer. Businesses must plan for an extended period of disruption. During this period, the designated party or counsel may also engage with OFAC's staff to clarify procedural questions, though substantive advocacy outside the written record carries risks and should be managed carefully.
If a transaction has already been frozen, or if a filing has been refused, an early and structured review can preserve options that narrow with time. The longer designation continues without a well-constructed challenge, the greater the practical and reputational harm.

How does OFAC's reconsideration process compare with OFSI, the EU, and the UN?
The US administrative-reconsideration route is broadly comparable in function to its counterparts, but the procedural architecture and evidentiary standards differ at each level – and a business subject to multiple regimes simultaneously must manage all of them in parallel.
Under the UK regime, OFSI (the Office of Financial Sanctions Implementation) administers designation challenges through a ministerial review process. The designated person may request a review of the decision on factual or legal grounds. Beyond the administrative review, a further challenge before the UK High Court is available by way of judicial review, and the relevant thematic UK sanctions regulations provide a statutory right to request a revocation or variation of a designation. The evidentiary approach is similar to OFAC's – the quality of the factual record matters enormously – but the procedural structure and the timelines differ.
Under the EU regime, designated persons may challenge a listing before the EU General Court by way of an annulment action. The Council of the EU also operates an administrative review procedure. A key structural difference is that EU designations are reviewable against EU fundamental-rights standards, including the right to an effective remedy under the Charter of Fundamental Rights. That avenue is not available against OFAC designations in US proceedings. EU General Court proceedings are formal adversarial processes with defined pleading stages; they are considerably more resource-intensive than an administrative reconsideration.
At the UN level, the Security Council Consolidated List is maintained by the relevant Sanctions Committees. For the ISIL/Al-Qaida list, a dedicated Ombudsperson hears de-listing petitions and provides an independent assessment to the Committee. For other UN lists, a Focal Point mechanism exists. UN de-listing is the most opaque and procedurally constrained of the three levels, and domestic implementation means that a UN de-listing does not automatically remove a parallel OFAC or OFSI designation.
Where a designation exists at more than one level – US, UK, EU, and UN simultaneously – the strategy must address each route on its own terms. A successful OFAC reconsideration does not automatically lift an EU or OFSI designation. In our cross-border practice, we regularly advise businesses managing parallel challenge processes across two or more regimes, which requires a co-ordinated evidential and timing strategy from the outset.
What are the principal risk flags in OFAC reconsideration submissions?
Most reconsideration submissions that fail do so for identifiable reasons. Understanding them in advance allows a submission to be structured to avoid them.
Incomplete or inconsistent ownership documentation. OFAC's 50 percent rule analysis depends entirely on the accuracy of the ownership record. If corporate-registry filings, shareholder agreements, and beneficial-ownership declarations are inconsistent with one another, OFAC will note the inconsistency and the submission will lose credibility at its core. Reconcile every discrepancy before submission, not after.
Over-reliance on assertions without evidence. Stating that the designated entity is independent of the blocking party is not evidence of independence. Demonstrating it – through board minutes, contractual terms, third-party valuations, audited accounts – is evidence. OFAC's reviewers are experienced in identifying submissions that assert facts without proving them.
Failure to address the actual designation criterion. A submission that rebuts the wrong criterion – for instance, arguing about beneficial ownership when OFAC designated on material-support grounds – is worse than no submission at all. Read the designation basis carefully and answer it directly.
Gaps in the timeline. If there is a period for which the designated party cannot account – funds transferred, contracts signed, intermediaries used – OFAC will draw the most unfavourable inference. Address gaps proactively; do not leave them for OFAC to discover.
Delay. There is no statute of limitations on a reconsideration request, but every day of designation is a day of business harm. Delay also allows the factual record to harden and witnesses to become unavailable. An early, well-prepared submission is almost always preferable to a later, perfect one that never arrives.
One persistent myth deserves direct correction: the view that OFAC will not delist a business with ongoing commercial connections to the relevant sector or region. In practice, OFAC evaluates the specific designation criteria; it does not delist or refuse to delist on the basis of sector membership alone. What matters is whether the grounds for the particular designation are sustained by the evidence. A business in a high-risk sector with a strong, documented rebuttal is in a better position than a business in an unrelated sector with a weak or unsupported submission.
When should you involve sanctions counsel – and what does that engagement look like?
The honest answer is: before you submit anything. A reconsideration submission, once filed, is part of the record. An ill-considered initial submission can be harder to recover from than no submission at all, because it sets the factual baseline that OFAC and, ultimately, a reviewing court will work from.
Counsel involvement at the earliest stage serves three functions. First, it imposes analytical rigour on the factual assessment: is this a genuine designation error, an ownership mischaracterisation, or a more contested factual dispute? Second, it ensures that the evidence package is built systematically, with legal-professional privilege protecting communications to the extent available. Third, it creates a co-ordinated strategy across regimes – if OFSI or the EU are also involved, the US submission does not inadvertently concede facts that complicate the parallel challenge.
We have acted for businesses, financial institutions, and individuals at each stage of this process – from the immediate post-designation crisis through to a concluded OFAC review. Our approach at Calder & Vance is to build the evidence package, prepare the petition, and manage the regulator's queries in a structured sequence aligned to the specific designation basis. We do not apply a template; each matter turns on its own facts.
