Sanctions Screening for Buyers: SDN List and the 50 Percent Rule

The Bank's Question Before the Prepayment

Days before a scheduled prepayment, the bank's compliance team asks you to confirm that the receiving party is not subject to sanctions. For a buyer who has spent months negotiating a container order of ceramic dinnerware, the request lands like an accusation. It is not: the bank runs this screen on every cross-border transfer, because money in transit passes through correspondent banks, and each of them must know who stands at the other end.

Buyers selling into European and North American markets meet the question in three forms: a bank asking for confirmation before a wire, an internal compliance team asking for supplier due diligence before a contract is signed, and a retailer requesting the supplier list for its vendor approval. Tableware is not sensitive merchandise, but sanctions attach to parties, ownership and payment routes, not to the nature of the goods: a dinner set bought from an entity that a sanctions authority treats as blocked is not a neutral purchase for any of them.

This guide is an operating map for importers, traders and the people who talk to banks: how the main screening frameworks work, which parties to cover, what the 50 percent rule means when you look through a supplier's shareholding, and what to keep on file so a bank, customs authority or customer can be answered in hours. The mechanisms below reflect official public sources as of September 2026; lists change without notice, so verify every transaction against current official publications before money moves. This is not legal advice; whether a specific transaction is permitted is a question for qualified compliance or legal counsel.

Why a Sanctions Question Reaches a Tableware Buyer

A buyer who has never touched a sanctions list can still be stopped by one, because the question arrives through three doors unrelated to the product category.

• The bank. Wires are screened by the sending bank, every correspondent in the chain and the receiving bank. A beneficiary, account bank or intermediate institution that matches or resembles a list entry makes the payment held or declined.
• Customs and the supply chain. Customs authorities, forwarders and shipping lines check parties and vessels against sanctions and export-control records. Vessel names are listed in their own right, and a carrier will not load a vessel that flags in its own screening.
• The customer. Retailers that sell into regulated markets screen their vendor base, including the suppliers you source through and their ultimate shareholders.

Each country's rules differ in scope. OFAC rules bind U.S. persons and transactions with a U.S. nexus; a buyer elsewhere follows its own law, and the UN framework binds states, which implement it nationally. The practical question is which layers touch your transaction. If it involves U.S. jurisdiction, treat the U.S. framework as applying to you; if it moves through or into the European Union, the EU layer applies; if your country has implemented UN sanctions by statute, that domestic law is the version you must meet. Every "should" below is conditional on the jurisdictions your transaction actually touches.

The U.S. Layer: OFAC and the SDN List

The U.S. Treasury's Office of Foreign Assets Control, known as OFAC, administers U.S. sanctions programs and publishes the Specially Designated Nationals and Blocked Persons List, the SDN List, which names individuals, entities, vessels and aircraft. OFAC rules prohibit U.S. persons from transacting, directly or indirectly, with anyone on the SDN List or with other blocked persons, and require U.S. persons to freeze the property that blocked persons own or control. U.S. persons include U.S. citizens and lawful permanent residents wherever located, anyone physically in the United States and entities organized under U.S. law.

Two features matter more than the list's size. First, it has no fixed update cycle: entries can be added, amended or removed at any time, so a name that cleared last month is no guarantee this month. Second, the list is only the visible surface: the duty to avoid blocked persons extends beyond printed names through the 50 percent rule. Screening is therefore a condition of dealing with any party that touches U.S. jurisdiction, and it is not one-time: screen at onboarding, again at each new order, and re-check when a corporate structure or shipping route changes.

The 50 Percent Rule: Screening Ownership, Not Just Names

A name check answers one question: is this party listed? The 50 percent rule exists because much sanctions evasion works by owning through, not appearing on, a list. Under the rule, an entity directly or indirectly owned in the aggregate of 50 percent or more by one or more blocked persons is treated as blocked even if it does not appear on any list. Three features decide how a supplier screen must be run.

• Ownership aggregates. If three shareholders each hold 20 percent of a supplier and each is a blocked person, the supplier is treated as blocked: the holdings count together, not one by one.
• Ownership is looked through layers. Indirect ownership counts. A blocked person may own a holding company that in turn owns the supplier, through several tiers, so the screen must trace the shareholding chain upward until the ultimate owners are visible, not stop at the entity that signed the contract.
• The rule covers ownership, not control. An entity controlled by a blocked person but owned below 50 percent is not automatically treated as blocked under the rule, although the authority may still designate it separately. That narrow line is why supplier screening is a facts exercise, not a judgment call.

Operationally, screening a supplier means screening its shareholding structure. After the registration documents, ask who the shareholders are up the chain, including nominees and holding companies, and compare each name against the applicable lists. The question is not whether the factory's legal name matches a list entry, but whether it is owned, through layers, by anyone who is listed. If your transaction involves U.S. jurisdiction and the structure shows aggregate ownership at or near the threshold through a blocked person, stop and have it confirmed by qualified compliance or legal counsel first.

Beyond the U.S.: UN Security Council and EU Layers

The U.S. framework is the one buyers meet first, but not the only one. Buyers selling into Europe or dealing with UN member states meet two further layers.

UN Security Council sanctions are established by resolutions under Chapter VII of the UN Charter. Each regime runs through a sanctions committee of representatives of the Council's fifteen member states, which handles listing and delisting, generally by consensus, and the Council publishes a consolidated list of designated persons and entities across regimes. UN sanctions bind all member states, but enforcement runs through each state's domestic law, so the list a company must obey is the national implementation, not the UN list itself.

The European Union calls these restrictive measures. They belong to the Common Foreign and Security Policy and are enacted as Council decisions combined with Council regulations, with a legal basis including Article 215 of the Treaty on the Functioning of the European Union. The EU acts autonomously or to implement UN decisions, and keeps a consolidated list of persons, groups and entities subject to EU financial sanctions, published by the EU's External Action Service, while the legally binding text is the version in the Official Journal. Measures are reviewed periodically, autonomous regimes typically on a roughly twelve-month cycle, and the EU Sanctions Map is the official entry point for the current state of each regime. The UK, after leaving the EU, keeps its own sanctions and export-control lists through its Treasury.

Across all layers the discipline is identical: know which regimes your transaction touches, screen against the current official version of each applicable list, and treat every list as moving.

Whom and What to Screen: A Party Map

A screen that checks only the supplier's trading name has not screened the transaction. Sanctions lists reach every party that touches an order, and the map below is the minimum a compliance-conscious buyer should cover.

Two habits make the map usable. Collect this information at onboarding rather than at payment time, and screen the transaction as well as the counterparty: a new port, a new account bank or a consignee that differs from the contract party is precisely when a listed name can enter an otherwise clean flow.

Screening the Right Way: Tools, Variants and Records

Free tools are a legitimate starting point, not a safe harbor. OFAC offers a free Sanctions List Search tool with approximate matching and adjustable confidence, and similar public search functions exist for other regimes. They answer "does this name resemble a listed name?" - the beginning of a screen, never the end. Larger institutions subscribe to commercial databases and embed checks into their transaction systems; a buyer's own screen should follow the same logic at a scale the trade justifies.

Three errors defeat most well-intentioned screens.

• Screening one spelling only. Suppliers operate under legal, trading, brand and translated or transliterated names; check the variants, and compare addresses as well as names, because addresses often confirm a resemblance.
• Treating a match as a verdict. A hit is a flag for human review, not a finding of guilt; lists contain common names, and a resembling supplier may be unrelated. Verify against full name, address, registration data and the ownership chain until the match is confirmed or excluded.
• Screening once. Lists have no fixed update cycle and ownership changes, so the screen belongs at onboarding, at every new order and at any structural event between.

Every screen should leave a record: the date, the tool or list version, the names checked, the result and, where a hit was resolved, the conclusion and its basis. When a bank asks a question, customs holds a shipment or a customer audits the vendor base, the file that answers in hours is the one built before the question was asked.

Red Lines, Early Signals and Records

Most of this work is routine screening, but a few situations admit no routine answer.

• Do not transact with a directly listed party. If the supplier, a shareholder in its chain, the consignee or the account bank is on an applicable list, the transaction does not proceed.
• Do not sign a contract with a blocked person's signature. If the individual signing or receiving funds for the supplier is listed or blocked, the signature route itself is the problem.
• Do not guess at a 50 percent structure. If ownership look-through suggests aggregate ownership at or near the threshold through a blocked person, obtain confirmation from qualified counsel first.
• Do not rely on the supplier's own assurance. A statement that the factory "is not sanctioned" is not a screen; the screen is your check against current official lists, over the ownership chain.

The earliest practical signal is often the bank itself: banks screen every payment, so a wire that is declined, frozen or returned for explanations is usually the first indication of a problem no internal review caught. The disciplined response is not to argue but to re-run the screen over the beneficiary, the account bank and the ownership chain, and to bring the file - screening records, ownership documents and verification conclusions. The same file answers a customs query or a customer's compliance questionnaire. A problem, when it appears, is rarely proof of wrongdoing; it is a test of documents assembled in advance.

The Screening Checklist

This guide reflects official public sources as of September 2026. Sanctions lists and the rules around them change continuously, so treat this checklist as a process rather than a set of names: verify every specific transaction against the most current official publications of the relevant authorities, and confirm the details with qualified compliance or legal counsel before acting.

• Identify the layers that touch the transaction, U.S., EU, UK or your own country's law, and screen only against the applicable ones.
• Collect the party map at onboarding: supplier entity and registration, shareholders up the chain, directors and signatories, bank details, ports and carriers.
• Run the screen against current official lists, over every party and vessel, with name variants and addresses.
• Apply the 50 percent rule by reading the ownership chain, and confirm any structure approaching the threshold through a blocked person with counsel.
• Resolve every hit by verification and record the conclusion; a resemblance is a question, not a verdict.
• Re-screen at each new order and structural event: ownership changes, new account banks, changed ports, a new carrier.
• Keep the file, every result, outcome and clearance basis, dated per supplier, because the file answers a bank, customs authority or customer.
