A Z2 analysis of the ownership dispute, the fragilities it exposed, and the impact on manufacturers
A sanctions trigger, a government seizure, and Chinese export controls turned Nexperia into one of the most consequential supply chain stories in recent memory. A trade deal eased the immediate crunch, but the dependency, quality, and inventory shockwaves are still reshaping the market.
It began when the U.S. Department of Commerce announced the BIS “Affiliates Rule” at the end of September, triggering sanctions on Dutch chipmaker Nexperia because of its acquisition by Wingtech Technology, which had been added to the BIS Entity List in December 2024.
In response, the Dutch government attempted to seize ownership of the company. Days later, China, where much of Nexperia’s manufacturing is based, struck back with export controls on Nexperia’s Chinese facilities and subcontractors, posing a substantial risk to manufacturing across Europe and the broader global supply chain.
Nexperia semiconductors coming out of China, where much of the company’s IC assembly takes place, are used in consumer electronics, aerospace and defense, and medical technology, among other industries.
The October trade deal suspended the BIS Affiliates Rule for a year and China granted exemptions for chips used in civilian applications like automotive. European automakers confirmed shipments resumed, but the relief does not resolve the deeper damage to the chip supply chain.
Chips from China feed consumer electronics, aerospace and defense, and medical tech. The bottleneck from the dispute and China’s export controls rippled across European manufacturing and beyond.
Nexperia B.V. stated it cannot guarantee the IP, technology, authenticity, or quality of products from its China facility as of October 13, even as the Chinese unit sources wafers locally to keep producing IGBT parts through 2026.
The dispute exposed Nexperia’s reliance on its Dongguan facilities and Chinese subcontractors, and manufacturers’ dependence on Nexperia parts. Neither side has an easy path to reduce that exposure.
A Z2 analysis identified the ten Nexperia commodity categories most exposed to the crisis, ranked by the number of MPNs assembled or fabricated in China and the share of each group produced there. Over three-quarters of Nexperia’s Zener diodes, GP BJTs, and switches/multiplexers/decoders are assembled in China, with strong implications for the auto industry.
| Commodity | Parts assembled in China | % assembled |
|---|---|---|
| Zener Diodes | 4,428 | 89% |
| Logic Gates & Inverters | 863 | 53% |
| GP BJTs | 1,543 | 75% |
| Buffers & Line Drivers | 573 | 57% |
| MOSFETs | 804 | 54% |
| Rectifiers | 906 | 58% |
| Transient Voltage Suppressors | 669 | 35% |
| Analog Switch Multiplexers | 224 | 70% |
| Switches, Multiplexers & Decoders | 269 | 78% |
| Digital BJTs | 486 | 51% |
Share of each commodity IC-assembled in China
Nexperia’s primary Chinese site is an IC assembly facility in Dongguan, Guangdong, but the company also relies on subcontractors for both assembly and fabrication. China’s export controls extend to these subcontractors, and the break in oversight between Nexperia B.V. and its Chinese units likely affected them too.
Z2’s analysis of the five weeks from October 13 to November 10 surfaced three inventory trends across Nexperia’s five highest-volume commodity types: GP BJTs, logic gates and inverters, MOSFETs, rectifiers, and Zener diodes.
Inventory declined steadily from mid-October. Available stock for Nexperia GP BJTs, MOSFETs, and rectifiers each fell by more than 40% in just over a month, and some distributors stopped listing Nexperia parts entirely.
Inventory for the five major alternatives (Diodes Incorporated, Infineon, onsemi, Texas Instruments, Vishay) also declined across Nexperia’s largest product lines, as customers sought crosses and buyers stockpiled ahead of a possible shortage.
Brokers aggressively expanded inventory of Nexperia crosses. GP BJTs from the major competitors jumped more than fifteenfold in October alone, while MOSFETs and rectifiers rose roughly 1,300% and 700%.
Broker inventory increase for Nexperia crosses (October)
Few parts are reaching critically low levels, but inventory for Nexperia parts and their crosses fell sharply among authorized distributors while broker supplies surged, signaling fast-changing dynamics and possible price swings. Z2 recommends firms take decisive, data-informed action:
See inventory across every distributor, authorized and independent, find the best crosses with the Cross Engine, and use part-to-site mapping to flag exactly which of your parts are built in China and most exposed to a Nexperia-style shock.
