SIA's origin count cuts the US, Europe and Japan share of chip equipment and materials spend to 68%
China supplies about 5% of the equipment and materials US chipmakers buy but over 90% of certain rare earths, the Semiconductor Industry Association says. Headquarters-based supplier counts understate the upstream dependency, so decoupling is harder to plan than the 5% suggests.
The Investor · Invest desk
95% of US chipmakers' equipment and materials spend went to firms headquartered in the US, Europe and Japan; counted by country of origin that share is 27 percentage points lower, about $7.3 billion a year originating elsewhere; China supplies about 5% by country of manufacture.
| Figure | Value | Note | Claim |

| Originates elsewhere | $7.3bn per yr, about | 9 | |
| China, by manufacture | 5% about | 1 |
What happened
- The SIA says 95% of the nearly $27 billion American chipmakers spend each year on manufacturing equipment and materials went to companies headquartered in the US, Europe and Japan.
- Counted by country of origin instead, that share dropped to 68%, according to the SIA.
- Suppliers "often rely on production chains outside their country of domicile," the SIA said in a report published Friday.
- Semafor adds a software channel: US startups use cheaper open-source Chinese AI, and nearly 300 US firms spoke out when the Trump administration considered banning it.
Why it matters
- constraint Switching to a US, European or Japanese vendor cannot close a 27-point gap, about $7.3 billion a year, because the gap sits in those vendors' own upstream supply.
- contradiction Semafor says more than 5% of supply "originate[s]" in China and cites 90% of the rare earths required; the SIA ties the 5% to manufacture and the 90% to certain rare earths. The wording changes what the 5% measures.
- decision An analyst sizing a chipmaker's China exposure has two inputs, 5% by manufacture or an origin share nobody has published, and the choice moves the estimate.
Start with the 5% as a cost line. On nearly $27 billion a year [4], and if the share applies to the same bill, 5% is about $1.35 billion [12]. That is small money, or rather it is small on a dollar basis.
The SIA took the 5% by country of manufacture [1]. On its origin count, if the 68% covers the same three regions as the 95%, up to 32% of the spend originates somewhere else [11], about 6.4 times the 5% direct share [13].
Kyle Chan, an AI specialist at Brookings, told The Washington Post "We're so deeply intertwined" and "There's a lot of actual dependency," Semafor reported [7]. For the one input where the SIA gives a concentration, certain rare earths, China holds over 90% [2].
In our view the spend line understates the exposure. Semafor describes the rare earths as those required to manufacture semiconductors [3], and a supplier holding over 90% of certain ones puts more at risk than those inputs' share of the bill. Neither account breaks out China's share on the origin count, prices the rare earths or gives a revenue-at-risk figure, so the gap between spend and exposure cannot be sized from what has been published.
The counter-case is that the 32% is mostly not China. If the SIA report assigns most of it to other countries, China's hidden share stays near 5% and the dependency narrows to the rare earths. A China origin share near 5%, or evidence that chipmakers can source those rare earths outside China, would mean we had read too much into the 68%.
What to watch
- Whether the SIA report or later coverage gives China's own share on the origin count: a figure near the 5% direct share weakens the thesis, one near the ceiling confirms it.
- Any chipmaker disclosure of rare earth sourcing outside China, which would test the 90% concentration figure.
- Whether the administration revives the ban on Chinese open-source AI that it considered.

More than 5% of equipment and materials supplied to US chipmakers originate in China, which also possesses some 90% of the rare earths required to manufacture semiconductors, a new report showed.

95% of the nearly $27 billion annual spending by American chipmakers on manufacturing equipment and materials was sourced from companies headquartered in the US, Europe and Japan.

The gap between the headquarters-based share and the origin-based share is 27 percentage points.

27 percentage points of nearly $27 billion is about $7.3 billion a year of spending with US, European and Japanese vendors that originates elsewhere.

The US tech startup ecosystem relies on cheaper, open-source Chinese AI, so much that when the Trump administration considered banning it, nearly 300 US firms spoke out.

If the 68% covers the same three regions as the 95%, up to 32% of the spend originates outside the US, Europe and Japan, which is a ceiling on China's share on the origin count.
- [12]
If the 5% direct share applies to the same $27 billion base, China-manufactured equipment and materials come to about $1.35 billion a year.
- [13]
The 32% ceiling is about 6.4 times the 5% direct share.
