Types of Sanctions and How They Affect Your Business

U.S. sanctions fall into three main types — comprehensive, list-based, and sectoral — and which ones reach your business depends on who you deal with, what you ship, and where it ends up. Understanding the categories is the difference between a quick screen and an expensive surprise. This guide breaks down each type and how to figure out your real exposure, without the legalese.

Watch — How to Deal with Sanctions as a Business:

Who imposes sanctions, and under what authority

Most U.S. economic sanctions are administered by the Office of Foreign Assets Control (OFAC) at the Treasury Department, acting under statutes like the International Emergency Economic Powers Act (IEEPA). The United Nations and the European Union run their own regimes, and U.S.-listed companies with overseas operations often have to reconcile all three. For a U.S. business, OFAC is the starting point. (See our overview of what OFAC is and how it affects your business.)

The three main types of sanctions

Comprehensive sanctions (country-wide embargoes)

Comprehensive sanctions effectively prohibit almost all trade and financial dealings with an entire country or region. If a country is comprehensively sanctioned, you generally cannot export to it, import from it, provide services to it, or process payments involving it without a specific OFAC license.

As of 2026, the comprehensively sanctioned jurisdictions are Cuba, Iran, and North Korea, along with the Russian-occupied Crimea, Donetsk, and Luhansk regions of Ukraine. Syria sat in this category for years, but U.S. policy shifted substantially in 2025 toward easing and winding down those restrictions — a reminder that the embargo list is not frozen in time. Always confirm a country’s current status against OFAC’s program pages before relying on it, because designations are added and lifted in response to world events.

List-based (targeted) sanctions

List-based sanctions target specific named individuals and entities rather than whole countries. The flagship list is OFAC’s Specially Designated Nationals and Blocked Persons List (SDN List). A party on the SDN List has its U.S.-reachable property blocked, and U.S. persons generally cannot transact with it — no matter what country it operates from.

The reach extends through ownership: under OFAC’s 50 Percent Rule, a company owned 50% or more by one or more blocked persons is blocked too, even if its own name is not on the list. Targeted sanctions are the type most businesses brush up against, which is why name-and-ownership screening matters for routine deals.

Sectoral sanctions

Sectoral sanctions sit between the two extremes. Instead of banning all dealings, they restrict specific activities in specific sectors of a target economy — for example, prohibiting certain financing, debt, or energy-technology transactions with named firms in a country’s banking or energy sector while leaving other dealings permitted. They are narrower and more technical, and they require reading the specific directive rather than assuming a yes/no answer.

A few related restrictions worth knowing

Beyond OFAC’s core programs, two adjacent controls often travel alongside sanctions. Export controls administered by the Commerce Department (the EAR) and the State Department (ITAR) restrict where certain goods, software, and technology can go, independent of OFAC. And trade remedies like anti-dumping and countervailing duties are a different mechanism entirely — they tax unfairly priced or subsidized imports rather than block dealings. Lumping these together is a common and costly mistake; each has its own agency, rules, and penalties.

How to tell which sanctions apply to you

Your exposure is a function of three variables, not one:

1. Who you deal with — customers, suppliers, banks, agents, and their beneficial owners. Screen them against the SDN List.
2. What you move — some goods, software, and technology carry export-control restrictions on top of sanctions.
3. Where it goes — the ultimate destination and any transshipment points, checked against comprehensive and sectoral programs.

Map a transaction against all three and you will usually know your risk before you commit. Where any answer is unclear, that is the moment to get a written read rather than proceed on assumption.

Frequently asked questions

What’s the difference between sanctions and an embargo? “Sanctions” is the umbrella term for all restrictive measures. An embargo is the most severe form — a near-total ban on dealings with a country or region. Every embargo is a sanction, but not every sanction is an embargo.

Do U.S. sanctions apply to my deals if I’m doing business abroad? They can. U.S. sanctions reach all U.S. persons worldwide, transactions with a U.S. nexus (such as U.S.-dollar clearing), and in some cases non-U.S. parties through secondary sanctions. Operating overseas does not put you outside their reach.

Are sanctions and tariffs the same thing? No. Tariffs and trade-remedy duties are taxes on imports. Sanctions restrict or prohibit dealings with particular countries or parties for foreign-policy reasons. They are administered by different agencies under different laws.

How often does the sanctions list change? Constantly. OFAC adds and removes designations regularly, and comprehensive programs shift with geopolitics. That is why one-time screening is never enough — you screen at onboarding and then monitor over the life of the relationship.
