A 2027 U.S.–China conflict with Australia aligned to the U.S. China trade stops immediately, Taiwan exports are slowed/limited, and China launches large‑scale cyber disruption in waves. Planning scenario, not a forecast. No end date is set.
The United States is a design and fab country with a large import bill, not an importer only. U.S.-headquartered semiconductor sales were 318.2 billion dollars. Firms based in the United States held 50.4 percent of shipments by company headquarters. Direct semiconductor employment was 345,000 jobs.
A China stop hits finished electrical goods harder than bare chips. WITS prints the U.S. electrical-machinery import total at 484,204,820.07 and China at 124,223,877.90, in thousands of U.S. dollars. China's calculated share of U.S. electrical-machinery imports is 25.66 percent. Mexico's calculated share of U.S. electrical-machinery imports is 18.25 percent. Mexico, Vietnam, Malaysia, Thailand, Korea, and Japan keep shipping that chapter.
Bare integrated circuits are a different bill. WITS prints the world total at 41,346,204.16 thousand dollars and China at 1,589,537.57. China's calculated share of U.S. integrated-circuit imports is 3.84 percent. The calculated Other Asia, nes share of U.S. integrated-circuit imports is 27.59 percent. Malaysia's calculated share of U.S. integrated-circuit imports is 23.41 percent. Malaysia, Israel, Korea, Ireland, and Mexico keep shipping bare chips if only China stops. Other Asia, nes is the lane the scenario slows, and it is not a pure Taiwan customs series.
Taiwan dependency is four different numbers. TrendForce prints TSMC at a 67 percent foundry market share on 26.85 billion dollars of fourth-quarter revenue. TSMC's own Foundry 2.0 share is 34 percent. Advanced technologies, 7-nanometer and beyond, were 69 percent of TSMC wafer revenue. Net revenue by platform was 51 percent HPC. Equipment trade is the separate customs line, not any of those shares.
Domestic wafer output continues at a smaller base than Taiwan. The EMSNow reprint of the SEMI forecast puts 2025 Americas capacity at 3.2 million wafers per month and Taiwan at 5.8 million, against a world total of 33.7 million, in 8-inch equivalents. TSMC's Arizona first fab entered high-volume N4 production in the fourth quarter of 2024. Three-nanometer, two-nanometer, and CoWoS expansion is still described in Taiwan.
The 0–3 month band is a short-horizon analog, not the full-year memory peak. The May print was 18 weeks. Memory contract prices rose over 20 percent in a month. Memory product sales rose 79.3 percent across the year, and that year print is not the 90-day band.
Materials are not the foundry share. China accounted for 99 percent of worldwide primary low-purity gallium production. U.S. net import reliance for gallium was 100 percent of reported consumption. In December 2024, China banned all exports of gallium to the United States.
Wave 1 is critical infrastructure and the gateways. Wave 2 is fabs' enterprise suppliers, design, EMS, and finance systems. Wave 3 is smaller board shops and retail repair. That order is a planning assignment on top of the CISA pre-positioning alert.
China trade stops on two different bills. Electrical machinery from China is 124,223,877.90 thousand dollars. Integrated circuits from China are 1,589,537.57 thousand dollars. The finished-goods stop is the larger cash hole. The bare-die stop is small next to Malaysia at 9,678,201.89 and Israel at 4,200,947.29 thousand dollars.
Taiwan exports slow on the largest bare-chip partner in this series. Other Asia, nes is 11,409,419.04 thousand dollars of U.S. integrated-circuit imports. UN Comtrade classifies Taiwan, Province of China as Other Asia, not elsewhere specified, code 490, and says other unspecified Asian territories can also land in that code. This report does not treat the residual as a pure Taiwan origin.
What keeps shipping on bare chips, if the Taiwan lane is the one that slows, is Malaysia, Israel, Korea at 2,455,700.09, Ireland at 1,918,690.04, and Mexico at 1,755,613.04 thousand dollars. Those partners are not a substitute for leading-edge capacity. Taiwan is forecast at 5.8 million wafers per month and the Americas at 3.2 million.
Finished electrical goods that keep shipping are Mexico at 88,361,378.76, Vietnam at 43,455,519.30, Malaysia at 28,679,092.03, Thailand at 23,008,062.95, Korea at 20,470,085.61, and Japan at 19,083,218.94 thousand dollars. Other Asia, nes on this chapter is 32,154,596.23 thousand dollars and carries the same code-490 caveat.
The wafer that still has to be made in Taiwan is not the same fact as customer headquarters. Advanced technologies were 69 percent of wafer revenue. Platform mix was 51 percent HPC, 35 percent smartphones, 6 percent IoT, 5 percent automotive, 1 percent DCE, and 2 percent other. Automotive at 5 percent is an end-market label, not the electronics-industry content share.
Gallium is the materials choke already in force. China's primary low-purity gallium price rose 17 percent. The June average was 380 dollars per kilogram. The December 2024 ban stops Chinese primary metal to the United States even when Malaysia still ships packaged chips.
Cyber disruption is the third hit. CISA, NSA, and FBI, with ACSC among the co-authors, say Volt Typhoon actors are seeking to pre-position on IT networks for disruptive or destructive activity against U.S. critical infrastructure in a major crisis or conflict.
Short-horizon price analog: DDR4 contract prices rose over 20 percent in a month. That monthly floor is the 0–3 month price band. Memory product sales rose 79.3 percent across a year, and that peak is not this band.
Short-horizon time analog: chip lead times increased by seven days to 18 weeks in May. The May print was 18 weeks. Power-management lead times hit 25.6 weeks. These are delivery times. They are not the year-over-year sales peak.
Half-year materials analog: China's primary low-purity gallium price rose 17 percent between January and June, from 325 to 380 dollars per kilogram. By October the price was 420 dollars per kilogram, an 11 percent increase from June that the page places after the first-half move.
Full-year product analog: Memory product sales rose 79.3 percent, to 165.5 billion dollars. Logic sales were 215.8 billion dollars, up 20.8 percent. The June gallium price was 58 percent above 240 dollars per kilogram a year earlier. Global sales later printed at 791.7 billion dollars, up 25.6 percent.
Wave 1 is critical infrastructure and chokepoints: fabs, ports, air gateways, and the systems inland freight and customs depend on. CISA says actors are pre-positioning for disruptive or destructive activity against U.S. critical infrastructure in a crisis or conflict.
Wave 2 is enterprise supply chain: design firms, equipment and materials indirectly, distributors, EMS, advanced packaging, cloud buyers, EDA indirectly, and trade credit indirectly.
Wave 3 is smaller firms: printed-circuit and module assemblers, and electronics retailers and repair.

The official TSMC annual-report PDF returned HTTP 403 and was not used for any figure. HTML pages of that report were read. Foundry 2.0 at 34 percent, advanced wafer revenue at 69 percent, platform mix, and customer headquarters are taken from those HTML pages.
Decision-changing limits. Other Asia, nes is UN code 490 and can include territories other than Taiwan. TrendForce 67 percent, TSMC Foundry 2.0 at 34 percent, the trade guide's over 60 percent and more than 90 percent, and the 69 percent wafer mix are different statistics. The 6.5 percent Taiwan headquarters share is not a foundry share. The China market of 185.1 billion dollars, the Asia Pacific prose total of 333.4 billion dollars, and the separate Asia Pacific / All Other market of 152.3 billion dollars are not forced into one ratio. End-use pie shares other than Government at 1.0 percent are unused. Distributor days of inventory, EMS revenue, Applied Materials ship-to geography, and an Arizona wafer count are unpublished here. The SIA memory sentence for the second product category says the increase was in 2024, to 223.1 billion dollars, inside a 2025 article. That year clause is not used as a 2025 fact.

Calculated shares use only printed WITS or ITA pairs and are rounded to two decimal places. They are 25.66 percent, 18.25 percent, 3.84 percent, 27.59 percent, 23.41 percent, 8.54 percent, 9.5 percent, and 18.77 percent. The 9.5 percent capacity share uses 3.2 and 33.7 from the EMSNow reprint. No other product in this report is a homemade statistic.
Cyber tags are not attack frequencies. Wafer fabs and gateways are Wave 1 direct. Inland trucking and export-control screening are Wave 1 indirect. Design, distributors, EMS, packaging, and cloud buyers are Wave 2 direct. Equipment, materials, EDA, and trade credit are Wave 2 indirect. Board shops and retailers are Wave 3 direct.
Tripwires at 18 weeks, 20 percent, 2.7 percent, 17 percent, and 50 percent of the printed China electrical line are planning lines. The 20 percent DDR4 figure is a floor because the page says over 20 percent. Gallium net import reliance of 100 percent excludes gallium-arsenide wafers. The SEMI capacity figures are a forecast reprinted by EMSNow, not a census of operating output.
