Washington re-tightens chip export controls on China

The test Between 26 Oct 2026 and 25 Oct 2027, BIS publishes in the Federal Register a final or interim final rule that tightens export controls on advanced chips or chipmaking tools for China, by narrowing the licence policy of 15 Jan 2026 or adding chips, tools, parts or memory to the China controls (a rule that only adds or changes Entity List entries does not count).

Impact is the average of the four parts, rounded, plus one point when Canada is directly hit on two or more channels, up to 10.

Two separate scales from 1 to 10. Strature never multiplies or merges them.

What changed

Dated, newest first

  1. China was 5% of TSMC's 3Q26 net revenue, against 8% in 3Q25. [11]

Why it matters

US chip policy toward China eased in 2026: H200-class chips moved to case-by-case review and the UAE got licence-free access. Nvidia's outlook assumes no data-centre compute revenue from China. Bills in Congress and past practice push towards a new tightening rule; the truce with Beijing is the main brake.

Why Likelihood 4 Pushes: the bill, May 2026 guidance, a possible truce lapse. Brakes: the administration eased in January and July 2026, the truce bargain, chip sales to China small on the figures cited.

Why Impact 6 Threshold case: one new BIS rule that tightens chip exports to China.

The other facts on file (6)
  • BIS moved H200-class chips for China and Macau from presumption of denial to case-by-case review, effective 15 Jan 2026. [2] (15 Jan 2026)
  • China shipments are capped at 50% of a product's shipments to US end users; a US third-party lab tests the chips before export. [2] (15 Jan 2026)
  • Proclamation 11002 put a 25% duty on certain advanced computing chips from 15 Jan 2026. [3] (20 Jan 2026)
  • Commerce announced on 10 Jul 2026, and published on 14 Jul, a rule moving the UAE to Country Group A:5. [4] (14 Jul 2026)
  • BIS revoked VEU status for Intel Dalian, Samsung China and SK hynix China, effective 31 Dec 2025. [6] (2 Sep 2025)
  • Nvidia's outlook assumes no Data Center compute revenue from China. [8] (26 Aug 2026)

  2. US sellersLicensed China sales of US chips and tools cut; tool sales not sized.
  3. Taiwan, South Korea, Netherlands, JapanForeign direct product rules carry US controls to their chips and tools.
  4. Trade politicsA new US rule risks China's paused controls.

Three scenarios and their signposts

  1. S1

    Easing holds

    BIS keeps case-by-case licensing; China keeps buying little.

  2. S2

    Tightening by statute

    Congress passes a licence requirement and BIS writes it into the rules.

  3. S3

    Tightening in a breakdown

    The truce lapses and BIS adds tools or parts.

The signposts of each scenario
PathSignpost
S1A new BIS licence notice or partner easing like the UAE's
S2H.R. 6875 reaches a floor vote
S3No Affiliates Rule notice by 9 Nov 2026

No probability is given for the three paths.

The other side

A tighter rule would steer more advanced chips to US and partner buyers; the January rule already caps China shipments at half of shipments to US end users [2]. Partners such as the UAE gain licence-free access when they line up with US rules [4].
