The Wassenaar Arrangement is a group of countries that agree to control exports of weapons and sensitive technology. It is a multilateral export-control regime for conventional arms and dual-use goods. Dual-use goods are items with both civilian and military uses, like advanced electronics, sensors, and encryption. The Arrangement gives member states a shared list of what to control. Each country then writes those controls into its own law.
It is not a treaty and it has no police power. Members join by choice and keep full control over their own export decisions. The goal is simple. Stop weapons and sensitive tech from reaching people who would use them to destabilize a region. If you handle exports or run compliance, this Arrangement shapes many of the rules you already follow.
A short history
During the Cold War, Western nations ran an export-control body called COCOM. Its job was to block strategic goods from reaching the Soviet bloc. When the Cold War ended, that focus no longer fit. COCOM shut down in 1994.
Governments agreed on a replacement in December 1995 in Wassenaar, a town in the Netherlands. That is where the name comes from. The new regime started work in 1996. Its first plenary meeting was held in Vienna, Austria, in April 1996. Vienna is still home to the Secretariat today.
The change in focus mattered. COCOM aimed at one bloc of countries. The Wassenaar Arrangement aims at destabilizing transfers anywhere. It watches the behavior of buyers, not a fixed list of enemy states.
Who takes part
The Arrangement has 42 participating states. It started with 33 founding members in 1996. Nine more have joined since, including India, South Africa, and Estonia. Members include the United States, most of Europe, Russia, Japan, Australia, and many others.
Some large exporters are not members. China, Israel, and Belarus are outside the Arrangement. That gap is one of its known weak spots. A buyer blocked in one country may still find a willing seller elsewhere.
New members are not admitted lightly. Applicants are judged on several factors:
- They must be a producer or exporter of arms or industrial equipment.
- They must maintain effective national export controls.
- They must adhere to the main non-proliferation regimes and treaties.
- They must apply the Arrangement’s control lists in their own law.
The two control lists
The Arrangement keeps two lists. Together they name the goods and technology members agree to control. Members review and update both lists every year.
The Munitions List
This list covers conventional military equipment. Think tanks, combat aircraft, warships, missiles, and small arms. These are items built for military use. Most countries already control them tightly.
The List of Dual-Use Goods and Technologies
This is the list most exporters run into. It covers items that have a normal commercial use and a possible military use. It is split into nine categories. Within it sit tiers for basic, sensitive, and very sensitive items. The very sensitive tier includes things like stealth materials and advanced radar.
| Category | Covers |
|---|---|
| 1. Special Materials | Advanced materials, chemicals, coatings |
| 2. Materials Processing | Machine tools, bearings, robots |
| 3. Electronics | Integrated circuits, microwave parts |
| 4. Computers | High-performance computing |
| 5. Telecommunications & Information Security | Encryption, network gear |
| 6. Sensors & Lasers | Cameras, radar, lasers, sonar |
| 7. Navigation & Avionics | Inertial systems, flight controls |
| 8. Marine | Submersibles, marine systems |
| 9. Aerospace & Propulsion | Engines, spacecraft, drones |
How it actually works
The Arrangement makes no binding orders. It sets standards. Each member takes the agreed lists and writes them into national law. Then each member decides on its own exports, case by case.
Decisions inside the Arrangement are made by consensus. The Plenary is the main decision body. It meets once a year, usually in December. Any single member can block a change. That keeps standards agreed by all, but it can also slow things down.
Transparency is a core tool. Members share information so they can spot risky patterns:
- They report arms transfers and dual-use export licenses to non-members twice a year.
- They report denials of sensitive dual-use items, in some cases within 60 days.
- They do not hold a veto over each other’s individual export decisions.
- Each state keeps sole responsibility for what it approves or blocks.
That last point matters. One member can approve a sale another member refused. This is called undercutting. The reporting rules exist to bring that into the open.
How it reaches your exports
You will rarely deal with the Arrangement directly. You deal with your own country’s version of its lists. In the United States, the Bureau of Industry and Security runs this. Learn more at the Bureau of Industry and Security, the agency that writes and enforces these controls.
The US Commerce Control List mirrors the Wassenaar dual-use categories. It uses the same numbering, then adds a nuclear category. Each controlled item gets an Export Control Classification Number, or ECCN. Your ECCN tells you which rules and license requirements apply. If you want the steps, see our guide on how to determine an ECCN number.
Here is the practical chain. The Arrangement sets the list. Your government adopts it. You classify your product against it. Then you decide if you need a license before you ship. For the wider picture, read what export controls are and export controls basics for international trade.
Wassenaar controls versus sanctions
People mix these up. They work in different ways. Export controls ask what you are shipping. Sanctions and screening ask who you are shipping to.
| Feature | Wassenaar-based controls | Sanctions screening |
|---|---|---|
| Main question | What is the item? | Who is the party? |
| Tool | Control lists and ECCNs | Restricted party lists |
| Trigger | Item is listed | Party is designated |
You often need both checks on the same order. A clean party can still need a license for a controlled item. A basic item can still be blocked because of the buyer. See the difference between export controls and sanctions for more. Screening the parties is where denied party screening comes in.
Common compliance steps
You do not need to memorize the Arrangement to stay compliant. You need a routine. A simple order of steps keeps you safe:
- Classify each product against your national control list.
- Record the ECCN or confirm the item is EAR99.
- Check the destination country against your rules.
- Screen every party in the deal against restricted lists.
- Decide if you need an export license before you ship.
- Keep records of each decision and each check.
Not every item is controlled. Many low-tech goods fall under EAR99 and need no license for most destinations. When you are unsure whether a shipment needs approval, work through whether you need an export license.
Frequently Asked Questions
Is the Wassenaar Arrangement legally binding?
No. It is not a treaty. It sets shared standards and lists. Members turn those into their own national laws. The legal force comes from each country’s law, not from the Arrangement itself.
How many countries are members?
There are 42 participating states. It began with 33 in 1996. Nine more joined later. China, Israel, and Belarus are notable non-members.
Does the Arrangement approve or block my exports?
No. It never touches your shipment. Your own government approves or blocks exports under national law. The Arrangement only shapes the lists your government uses.
How does it affect encryption products?
Encryption sits in Category 5 of the dual-use list, under information security. Many countries control it. That is why some software and hardware need review before export, even to friendly markets.
Key Takeaways
The Wassenaar Arrangement is a voluntary group of 42 states that agree on what arms and dual-use goods to control. It sets two lists, a Munitions List and a dual-use list, and updates them each year. It makes no binding orders and blocks no shipments. Each member writes the lists into national law and decides its own exports. For you, the practical work is the same as always. Classify your item, check the destination, screen the parties, and keep clean records. If you want help building that routine, contact our team.
