The nonproliferation sanctions list is a set of parties the U.S. State Department has sanctioned. These parties are named for activities tied to the spread of weapons of mass destruction. That includes nuclear, chemical, and biological weapons, plus the missiles and systems used to deliver them. If your company deals in sensitive goods or technology, this list matters to you.
The State Department runs several nonproliferation programs. Each one comes from a specific U.S. law. When a party breaks one of those laws, the government can impose sanctions and publish the name. Screening against these names is a normal part of denied party screening. This guide explains what the list is, who is on it, and what you should do.
What the nonproliferation sanctions list covers
The list is not one single file. It is a group of sanctions actions taken under U.S. nonproliferation laws. The State Department, through its Bureau of International Security and Nonproliferation, manages these programs. The focus is on stopping the spread of weapons of mass destruction and their delivery systems.
Parties end up on the list when they help build, supply, or transfer items linked to these weapons. The sanctioned party can be a company, a person, or a government body. Once sanctioned, they face limits on trade and dealings with the United States.
The laws behind the sanctions
Several U.S. laws give the State Department power to impose these sanctions. Each law targets a different concern. Here are some of the main ones you may see referenced.
- The Iran, North Korea, and Syria Nonproliferation Act. It targets transfers of goods and technology to or from those countries.
- The Chemical and Biological Weapons Control and Warfare Elimination Act. It addresses the use of chemical or biological weapons.
- Executive Order 13382. It targets proliferators of weapons of mass destruction and those who support them.
- The Arms Export Control Act. It can trigger sanctions for missile technology transfers.
The exact legal basis shapes what the sanction blocks. Some laws bar U.S. government contracts. Others block licenses for exports. It depends on the program and the party.
How it differs from other U.S. lists
Many people mix up the U.S. restricted party lists. Different agencies keep different lists for different reasons. The table below shows where the nonproliferation sanctions list sits among the common ones.
| List | Agency | Main focus |
|---|---|---|
| Nonproliferation sanctions | State Department | Weapons of mass destruction and delivery systems |
| SDN List | Treasury (OFAC) | Blocked persons under sanctions programs |
| Entity List | Commerce (BIS) | Parties of national security concern |
| Denied Persons List | Commerce (BIS) | Parties denied export privileges |
You can read more about each in our guides to the OFAC SDN List, the BIS Entity List, and the Denied Persons List. Each one has its own rules and effects.
Where to find the list
The State Department publishes nonproliferation sanctions actions in the Federal Register. It also lists them on its own website under the nonproliferation programs. That is the primary source when you need the official record.
For day to day work, many parties from these actions also appear in the Consolidated Screening List. That tool brings several U.S. lists into one search. It saves time when you screen names across agencies.
Why it matters for your business
Dealing with a sanctioned party can carry heavy costs. You could lose export privileges. You could face fines. You could damage your reputation with banks and partners. This is true even if the deal seemed small or routine.
Who should pay attention
Any firm that sells dual-use goods, chemicals, electronics, or advanced technology should care. Freight forwarders and brokers who move such goods should care too. If you are unsure whether this applies to you, see our guide on who needs to do denied party screening.
Watch for evasion signs
Proliferation networks often hide behind front companies and odd routing. Learn the common sanctions evasion red flags so you can spot trouble early. A vague end user or a strange shipping path is worth a second look.
How to screen against the list
Screening does not need to be hard. A clear process keeps you consistent. Follow these steps for each transaction.
- Collect full names and addresses for every party in the deal.
- Screen those names against U.S. lists, including nonproliferation sanctions.
- Review any hit carefully before you clear or block it.
- Rule out or confirm each match to remove false alarms.
- Keep records of the check and the result.

Frequently Asked Questions
Who maintains the nonproliferation sanctions list?
The U.S. State Department maintains it. Its Bureau of International Security and Nonproliferation runs the programs. Actions are published in the Federal Register and on the department’s website.
Is it the same as the OFAC SDN List?
No. The SDN List is kept by Treasury’s OFAC. The nonproliferation sanctions list comes from the State Department under different laws. Some parties may appear on both, but they are separate lists.
How often should I screen against it?
Screen before each transaction and when parties change. Lists update over time, so a clear party today may not stay clear. See our guide on how often to run denied party screening.
