Key Takeaways
- A C4ADS report reveals three primary channels through which advanced U.S. AI accelerators reach China despite export bans: university purchases, drop‑shipping via Southeast Asian hubs, and opaque shell‑company networks.
- The report documents $6.48 million of chips sent to Chinese research institutions between 2024‑early 2026 and $13.4 million routed through Vietnam, India, and Malaysia from 2022‑2025.
- A single entity, Megaspeed International, is linked to $4.6 billion worth of silicon flowing to China, highlighting the scale of covert transshipment.
- C4ADS recommends strengthening end‑user verification, allocating more resources to the U.S. Bureau of Industry and Security (BIS), and embedding geopolitical risk analysis into corporate supply‑chain frameworks.
Overview of the C4ADS Findings
The nonprofit monitoring group C4ADS, which receives most of its funding from the U.S. government, released a report detailing how “American AI accelerators reach China” despite formal restrictions. The authors note that “only explicitly mentioned chips are accounted for, meaning the actual amount of hardware changing hands could be far higher.” They identify three major avenues for chip smuggling: direct acquisitions via Chinese research institutions, drop‑shipping through other Southeast Asian countries, and purchases routed through a matryoshka‑doll‑like structure of shell companies.
U.S. Export Controls and China’s Official Stance
Under current U.S. policy, “the sale of H100, A100, and Blackwell-family chips to China” is prohibited, while lower‑end parts such as the H20 and H200 (and AMD’s MI325X) may be traded case‑by‑case, the latter incurring a 25 % tariff. China, meanwhile, “discourages and restricts the purchase of American AI chips” to bolster domestic efforts led by Huawei, yet “multiple reports indicate the authorities often turn a blind eye to gray/black‑market imports,” with official exceptions granted in 2026 to giants like ByteDance, Alibaba, and Tencent.
Method 1: University and Research‑Institution Purchases
The first quasi‑legal route involves Chinese universities or research bodies buying the forbidden chips. According to C4ADS, these entities “reportedly include Nvidia GPUs inside ‘sprawling multi‑vendor contracts,’ routed through small Chinese regional integrators.” The report adds that “some buyer institutions have ties to the CCP and the country’s defense and intelligence sectors.” In the July 2025‑January 2026 window, C4ADS tracked “56 chips worth $1.7 million sold this way,” and a broader 2024 investigation uncovered “$6.48 million worth of silicon heading to China” via this channel.
Method 2: Drop‑Shipping Through Southeast Asia
A second, technically legal pathway uses drop‑shipping via nations such as Vietnam, India, and Malaysia. C4ADS analyzed transactions from 2022 to 2025 and found “$13.4 million of Nvidia A100, H100/GH100, and AD102-series GPUs routed through the aforementioned countries, in a ‘consistent pattern.’” Some chips moved from Taiwan to Vietnam, possibly exploiting local testing facilities as a pretext. The investigation notes that “the timing, volume, and destination of many shipments could obscure their true intent.” A portion of the flow continued to Hong Kong, where two firms—Profit New Limited and ELB International Limited—“dominate the import side,” with Profit New Limited alone trading “$8.7 million of silicon in a single day in March 2025,” likely ahead of tighter export controls that took effect in April 2025. Suspiciously, several high‑value shipments lacked cost, insurance, weight, or freight values and displayed “nice round zeros in their import value declarations,” raising doubts about the accuracy of the paperwork.
Method 3: Shell‑Company Networks and Megaspeed International
The largest share of illicit silicon flows through opaque ownership structures. C4ADS states that “this method accounted for $4.6 billion worth of intelligent sand migrating to China, on the account of just one entity, Megaspeed International.” Megaspeed was the biggest Southeast Asian importer of Nvidia hardware between 2023 and 2025, yet its “actual ownership is ‘unresolved.’” The firm has subsidiaries across Singapore, Indonesia, and Malaysia, was purchased in 2023 by Singapore‑based Swiftdata, and prior to that was owned by Chinese gaming company 7Road Holdings. During the transition, Chinese businesswoman Huang Le served as a temporary major shareholder and remains a director of a Hong Kong firm that bought transceivers from Megaspeed Indonesia; C4ADS observes that “Le may still be calling the shots at Megaspeed,” citing her identification as the firm’s chairwoman at a conference as recently as 2025. The rapid reshuffling of ownership and the fact that Megaspeed reportedly obtained export‑locked Blackwell chips make its dealings “more than a tad murky.”
Scale of Smuggling and Strategic Implications
Combining the three channels, the report suggests that a substantial fraction of China’s AI compute capacity is built on smuggled U.S. silicon. An earlier Epoch AI study estimated that “around a third (and possibly most of) China’s AI compute power is comprised of smuggled GPUs.” This influx enables Chinese firms and state‑linked laboratories to continue training large‑scale models despite official bans, potentially narrowing the technological gap with the United States and eroding the effectiveness of export controls as a strategic lever.
Recommendations from C4ADS
To curb these flows, C4ADS urges the U.S. Bureau of Industry and Security to receive “additional staff and resources so it can verify where the wares landed after their sale, and who their end users are.” The authors acknowledge that such verification would demand cooperation from other nations, which may be difficult amid current geopolitical tensions. In their own words, “U.S. and friend‑shored semiconductor manufacturers, equipment makers, and distributors should invest in a robust end‑user verification system that goes beyond standard restricted‑party list screening, incorporating on‑the‑ground due diligence, corporate ownership tracing, and post‑shipment verification.” For private companies, the report advises integrating “geopolitical and risk analysis into their frameworks… to assess if their direct or downstream customers could be selling wares to China’s military or intelligence sectors.”
Conclusion
The C4ADS investigation illuminates a sophisticated, multi‑layered evasion network that blends quasi‑legal academic purchases, regional transshipment hubs, and convoluted shell‑company arrangements to funnel billions of dollars’ worth of cutting‑edge AI chips into China. While U.S. export rules remain formally strict, the practical enforcement gaps uncovered by the report suggest that policy alone is insufficient. Strengthening end‑user verification, allocating more enforcement capacity, and compelling corporations to scrutinize the ultimate destinations of their products are essential steps if the United States hopes to preserve its technological edge and prevent advanced semiconductors from bolstering China’s military and AI ambitions.
