From Smuggling Scheme Uses Low-End Processors to Bypass Chip Export Rules

How could the smuggling of restricted high-bandwidth memory affect China?

Likely What happens if… A possibility worth considering, not a forecast.

Smuggling scheme increases restricted memory supply into China The smuggling scheme exploits a gap in US export regulations by pairing high-bandwidth memory (HBM) from Samsung and SK hynix with deliberately useless processors. These packages are manufactured in packaging houses across Southeast Asia and South Korea, then smuggled into mainland China. Once inside, workshops heat the packages to pry off the HBM stacks, which are then sold to Chinese customers, such as Huawei. This process increases the availability of restricted memory components in the Chinese market, while simultaneously challenging the integrity of international export controls.

How it reaches China

Reported by news outlets

From the export point, the packages are smuggled into mainland China via luggage, car trunks, and the bags of daily cross-border commuters. This allows the restricted components to bypass formal customs checks. In workshops in Shenzhen, the packages are heated until the solder gives way, allowing the memory stacks to be pried off and sold for about $4,000 a stack, primarily to Huawei customers. This increases the supply of restricted HBM in the Chinese market.

Why it matters

The availability of restricted high-bandwidth memory is critical for China's domestic AI industry and its ability to compete globally. By circumventing US export controls, this smuggling scheme provides a vital, albeit illicit, supply channel for components needed by major Chinese tech firms, helping to sustain the appetite for advanced AI accelerators.

This activity highlights the ongoing tension between global technology supply chains and national security regulations. The precedent is significant, as other companies, such as TSMC, have faced US investigations after their chips were found in Huawei products, underscoring the high stakes of maintaining compliance with international trade restrictions.

What we don't know yet

Will the US Commerce Department's Bureau of Industry and Security (BIS) clarify the rules regarding co-packaged chips?
How will Chinese regulators respond to the circumvention of international export controls?

What would change this answer

BIS issues red-flag warnings on packaged HBM deployed in ways that allow easy removalThe smuggling scheme would become significantly riskier and less functional, potentially reducing the supply of restricted memory.

Chinese AI memory appetite significantly decreasesThe incentive for the smuggling operation would diminish, making the market for processors nobody wants less healthy.
