Chip Export Rules Tighten
US lawmakers push for stricter regulations on contract chipmakers supplying Chinese overseas units.

A bipartisan pair of U.S. senators pushed the Trump administration on June 8 to close a major gap in chip export rules. Senators Jim Banks (R-IN) and Andy Kim (D-NJ) sent a formal letter to the Bureau of Industry and Security, urging tighter controls on contract chipmakers like Taiwan Semiconductor Manufacturing Co. (TSMC) Reuters. Their concern: Chinese firms could use front companies to secretly order custom-made AI chips from foundries, bypassing rules aimed at cutting off Beijing's access to advanced semiconductor technology.
The push follows a June 1 clarification from the BIS — the Commerce Department office that enforces export laws — stating that selling advanced chips like Nvidia's Blackwell to any company whose parent is headquartered in China requires a U.S. license, no matter where the sale takes place Reuters. But experts warn that clarification leaves a dangerous door open.
How Hundreds of Thousands of Chips Slipped Through
The story starts in May 2025, when the Trump administration paused enforcement of the so-called 'AI Diffusion rule.' Many companies read this as a green light. Chinese tech giants like Alibaba and ByteDance rushed to set up data centers in Malaysia, Singapore, and the UAE, ordering chips through local subsidiaries Reuters. During this window, an estimated 100,000 or more advanced Nvidia and AMD AI chips reached Chinese-controlled units in Southeast Asia, according to Reuters.
Malaysia alone saw a 366% spike in AI chip shipments during the enforcement gap, according to reporting by Reuters. On June 1, 2026, the BIS issued updated guidance signaling that the parent-company rule had technically been in force all along. Trade lawyers call it a 'restatement' rather than a new law — a way to close the gap without admitting one existed.
The 'Front Company' Loophole Lawmakers Want Closed
The June 1 guidance fixed one problem but left another wide open. Even if Chinese subsidiaries can no longer buy off-the-shelf Nvidia chips, they could still hire TSMC or Samsung to manufacture custom AI chips — like Huawei's Ascend line — using front companies to hide the real owner. Former State Department official Chris McGuire called this a 'HUGE problem,' noting that foundries like TSMC currently face far less scrutiny than direct chip sellers Reuters.
Senators Banks and Kim argue that 'failing to address this gap could weaken U.S. national security' and fuel China's military capabilities, according to Reuters. Their letter asks BIS chief Jeffrey Kessler to require contract manufacturers to adopt strict 'Know Your Customer' checks — the same kind of due diligence that banks use to verify who they're really doing business with.
Bipartisan Pressure Builds Alongside Stiff Penalties
Banks and Kim are not alone. House Select Committee on China Chairman John Moolenaar (R-MI) and Ranking Member Raja Krishnamoorthi (D-IL) have also been pushing action. They recently introduced the Stop Stealing Our Chips Act to crack down on semiconductor smuggling. The BIS has backed up the political pressure with real enforcement — Applied Materials recently paid a $252 million penalty for export control violations tied to China's SMIC chipmaker, according to Reuters.
New proposals on the table would also impose a 25% tariff on any chips that pass through Chinese-linked supply chains before entering the U.S. BIS chief Kessler has said that 'export controls should evolve with changes in technology, while protecting national security.' So far, the BIS has not formally responded to the June 8 letter on contract manufacturers.
Southeast Asia's Chip Boom Faces a Sudden Chill
The rule changes carry big economic consequences beyond Washington. Countries like Malaysia built an investment boom on data center deals during the 2025 enforcement gap. If strict licensing now applies to all Chinese parent-company subsidiaries regardless of location, that boom could cool fast. China's Commerce Ministry has already pushed back, with spokesperson He Yongqian calling the moves an 'abuse of export controls' that 'destabilizes the global semiconductor supply chain,' according to Reuters.
For Nvidia, the guidance changes little in practice — the company says the government had already privately warned it about the licensing rules. But for contract manufacturers like TSMC, the pressure is new and growing. Lawmakers want foundries held to the same strict standard as chip sellers. Whether the BIS acts on that demand could define the next chapter of the U.S.-China tech war.
