export restriction

in English: export control

basicwidespread

A state regulation that prohibits or requires a license to sell certain advanced technologies – such as AI chips – to specific countries or companies.

In plain terms

Export controls mean a state defines what, to whom, and where goods can be sold abroad. These are not everyday commodities but technologies that could provide military or strategic advantage. In the AI world, these are primarily the most powerful chips and chip-making machines; in the United States, restrictions on trained models (model weights) were put on the agenda in 2025, but that rule was withdrawn.

It is like a prescription drug at a pharmacy. The product exists, and the manufacturer is willing to sell it, but it is only dispensed to those with permission. Here, the 'prescription' is the export license, and the 'pharmacist' is the authority that checks who the buyer is and what they intend to use the goods for.

It has become a constant feature in AI news because training large models requires vast numbers of top-tier chips, which only a few companies can design and manufacture. Whoever controls the path of these chips influences how quickly any country can build advanced AI.

It differs from a tariff or a sanction. A tariff makes goods more expensive; a sanction punishes a country or a person. An export control regulates the outflow of a specific technology, and what decides is whether a licence exists, not the price.

How it works

The authority compiles a list of controlled products. For AI chips, it typically sets technical thresholds, such as computing power: anything above this requires a license.
It also determines where and to whom goods cannot go. There are country lists and company-specific lists (colloquially blacklists) on which specific companies and research institutes appear; they can only be supplied with special permission, and the authority usually denies this permission.
The seller must verify the buyer and the end use before shipment. If the product or the destination is affected, a license must be requested, which the authority may grant, attach conditions to, or refuse.
The rule may also apply beyond the border. For example, US regulations can apply to products manufactured abroad if they were made with US technology.
The authority also checks afterwards. Violations can lead to heavy fines, loss of permits, and criminal proceedings in cases of intentional circumvention.

An everyday example

You read in the news that a chipmaker is producing a separate, weakened version for the Chinese market, or that its share price fell due to a new Washington regulation. Both are underpinned by export controls: the company cannot freely sell its strongest product there. However, an AI service being unavailable in certain countries is usually not due to export controls, but rather sanctions, local regulations, or the provider's business decision.

Who is affected

entrepreneur, executiveIf your company sells advanced hardware, software, or technical expertise abroad, you must know whether it requires a license and who the end user is.

bank customer, investorA single new rule can rewrite the revenue outlooks of chipmakers and AI companies within days, thus affecting their stock prices. → Money

A common misconception

MythAn export ban is a total prohibition after which the affected country cannot access the technology at all.

In realityIn most cases these are licensing regimes, not total bans, and weaker products can be sold freely. The restrictions mainly slow things down and raise costs: through workarounds, smuggling and in-house development, part of the technology still gets through.

Limits and risks

Rules change quickly and according to political decisions, so a news item from six months ago may already be outdated. Always check the date.
The impact of restrictions is debated: it slows down the target country but also encourages it to build its own chip industry.
Enforcement is difficult because chips are small and can be transferred via intermediary countries, while computing capacity can be rented remotely via the cloud.
The restriction could also affect allied countries and smaller markets. A US rule from early 2025 would have classified countries based on how many AI chips they could purchase, but this was withdrawn in 2025.

Similar, but not the same

sanction – Sanctions punish a country, company, or individual with general economic prohibitions, whereas export restrictions regulate the export of a specific technology.
customs – A tariff is a financial burden that makes goods more expensive, but after payment they can move freely; in export restrictions, the permit decides, not the price.
data localization – Data localization requires that data remain within a country, while export controls apply to the export of equipment, software, and technical knowledge.

A brief history

Export of strategic technologies has been restricted since the Cold War: the Western coordinating body, COCOM, ceased to exist in 1994, replaced in 1996 by the Wassenaar Arrangement. The AI-specific era began in October 2022, when the United States made the export of the most advanced AI chips and chip manufacturing equipment to China subject to licensing.

Where things stand

At the end of 2026, export controls are one of the main geopolitical tools of the AI race, especially between the United States and China. China uses them too: among other things, it makes exports of rare earth elements and other raw materials important for chip manufacturing subject to licensing. The detailed rules (which chips, to which countries, under what conditions) change frequently; in the EU, the regulation on dual-use items provides the framework.
