Chip export controls

Also called export controls, AI chip ban

Chip export controls are government rules that limit which countries and companies may buy the most powerful AI chips and the machines that make them.

Chips and scaleCurious

Products, laws and numbers here change fast. Checked October 2026.

In plain words

The best AI chips, and the machines that build them, come from a small number of countries, chiefly the United States and its partners. Since 2022 the US government has used export rules to decide who may buy them. A seller needs a licence to ship the most powerful AI chips to certain countries, and for some destinations that licence is usually refused.

The main target is China. The stated reason is national security. The rules cover the chips themselves, the tools for making them and, since 2024, the fast memory AI chips depend on. The Netherlands and Japan have added limits of their own on chipmaking machines.

China has answered with limits on exports of gallium and germanium, metals used in making chips, and with a push to build its own AI chips. Most other countries, including India, face no US caps on buying AI chips as of October 2026, after a plan to cap sales to them was dropped in 2025.

Everyday example

The only ovens in town

Imagine one family of sweet makers owns the only ovens hot enough for a famous mithai, and also sells those ovens. If the town council tells them which customers may buy the ovens, rivals must make do with older ovens or spend years building their own. Chip export controls work like that council: a government decides who may buy the most advanced chips and the machines that make them.

Where the example breaks: A town council's rules stop at the town's edge. US export rules reach further: they can cover chips made abroad with American tools or designs, and buyers based in third countries, which makes them hard to enforce and often disputed.

How it actually works

In the US, export controls are run by the Commerce Department's Bureau of Industry and Security (BIS). They have changed many times since 2022, so dates matter.

  1. October 2022: the first broad rules

    BIS required licences to export advanced AI chips and some chipmaking equipment to China, and barred US people from helping certain Chinese chip factories without a licence. Applications were reviewed under a presumption of denial.

  2. 2023 to 2025: tightening

    An update in force from November 2023 widened the chip limits and covered companies headquartered in China wherever they operate. In December 2024 the US added HBM memory to its controls and 140 organisations to its Entity List. In April 2025 even Nvidia's H20, a lower-powered chip it sold in China, needed a licence.

  3. 2025: a global plan, then a reversal

    In January 2025 the US issued the AI Diffusion Rule, which sorted countries into three tiers and would have capped chip sales to most of them, India among them. In May 2025, two days before companies would have had to comply, the new administration said it would not enforce it.

  4. 2026: licences with conditions

    From January 2026, sales of chips like Nvidia's H200 to approved Chinese buyers moved to case-by-case review, with conditions and a 25% US duty. The newest chips, such as Nvidia's Blackwell, remain barred. On 31 May 2026 BIS confirmed that licences are still needed for China-headquartered firms anywhere in the world.

  5. How others are affected

    China required licences for gallium and germanium exports from August 2023 and banned them to the US in December 2024, and has reportedly told firms to prefer home-grown chips such as Huawei's. India faces no US limits on AI chips as of October 2026; its IndiaAI Mission had brought more than 38,000 GPUs onto a shared government platform by March 2026.

Do chip export controls work?

One view

They slow rivals down

Top AI chips are harder and costlier to get in China, which limits how much computing its labs can use for the biggest training runs.

The other view

They backfire

They cost US firms sales, encourage smuggling through third countries, and push China to build its own chip industry faster.

Most likely: Both effects are real. The controls have made advanced chips harder, but not impossible, to obtain in China, and have also spurred its own chip efforts. Whether the trade-off is worth it is a policy judgement on which governments and experts differ.

Questions people ask

Why does the US restrict AI chip exports to China?

The US government says the rules protect national security. Its October 2022 announcement said advanced chips help China's military planning and weapons programmes and can be used for surveillance and human rights abuses. China has objected and answered with export limits of its own, saying it is protecting its rights and interests.

Can India buy Nvidia AI chips?

Yes. As of October 2026 India faces no US export limits on advanced AI chips, and Nvidia and AMD GPUs are sold there. The 2025 AI Diffusion Rule would have placed India in a middle tier with caps, but it was dropped before it took effect.

What was the AI Diffusion Rule?

A US rule issued in January 2025 that would have required licences for advanced AI chips worldwide, sorting countries into three tiers: close allies with open access, most countries with caps, and embargoed countries such as China with near-total limits. It was withdrawn in May 2025 before taking effect.

Do export controls cover AI models too?

Rarely so far. The 2025 Diffusion Rule would have controlled the weights of the most powerful closed models, but it was dropped. In June 2026 the Commerce Department applied export controls to two Anthropic models, Fable 5 and Mythos 5. Anthropic suspended access on 12 June to comply. The controls were lifted on 30 June and access returned on 1 July.

What is the difference between export controls and tariffs?

A tariff is a tax on goods crossing a border, which makes them dearer but still allowed. An export control is a permission rule: some goods cannot be sent to some buyers at all without a government licence. The US now uses both on AI chips.
