Introduction:
The U.S. government is thinking about ending chip tool waivers that allow top chipmakers like TSMC, Samsung, and SK hynix to buy American chipmaking tools for their factories in China.
These waivers were created to avoid disrupting global chip supply chains while still limiting China’s access to advanced technology.
But now, with rising trade tensions and China’s tighter control over rare earth exports, the U.S. may tighten the rules—putting key global semiconductor operations at risk.

At a Glance: Key Takeaways in 5 Points
Waivers Under Review: The U.S. is considering ending export waivers for American chip tools to foreign chipmakers operating in China.
Impact Targets: TSMC, Samsung, and SK hynix use these waivers to import essential tools for legacy and memory chip production.
Tools in Question: Restrictions could block equipment like etching, deposition, and metrology machines made by U.S. firms.
China’s Pushback: China has limited rare earth export licenses to six months—fueling the tech and trade rivalry.
Strategic Stakes: The U.S. aims to cut China off from tech, but risks alienating key allies and losing market dominance.

Background: Why the Waivers Mattered?
In October 2022, the U.S. began limiting exports of advanced semiconductor tools to China, aiming to curb its AI and military development.
But to keep global supply chains steady, Washington granted waivers to foreign firms—mainly TSMC (Taiwan), Samsung and SK hynix (South Korea)—for their Chinese fabs.
These waivers allowed them to buy U.S. chipmaking tools without special government licenses. They were seen as a compromise to protect U.S. companies like Lam Research, KLA Corp, and Applied Materials, which supply vital semiconductor equipment.
What Might Change: The Kessler Doctrine
Earlier this month, Jeffrey Kessler, Under Secretary of Commerce for Industry and Security, told lawmakers and industry insiders that the waivers may be revoked.
According to The Wall Street Journal and Reuters, Kessler warned chipmakers the U.S. must close loopholes that help “adversaries cultivate their technology.”
He emphasized that partnerships with allies must evolve to stop sensitive tech from leaking into Chinese hands.

Tools on the Chopping Block
Here’s what the potential restrictions could hit:
| Tool Type | Function | Key U.S. Supplier |
|---|---|---|
| Etching Equipment | Carves patterns into wafers | Lam Research |
| Deposition Tools | Applies thin material layers | Applied Materials |
| Metrology Tools | Inspects wafer quality | KLA Corporation |
These machines are critical even for producing mature-node chips and memory, not just cutting-edge processors.

The Rare Earth Bargain: What’s Driving This?
The move also appears to be retaliation against China’s rare earth policy. Beijing recently introduced six-month expiration dates on export licenses for rare earth minerals—used in magnets, chips, and defense tech.
Washington wants guaranteed long-term access to these materials. Ending tool waivers may be a bargaining chip in trade talks.

The Domino Effect: Risks of Overreach
Ending these waivers could cause ripple effects:
- U.S. toolmakers may lose billions in sales.
- South Korea and Taiwan may see this as a threat to business stability.
- China may accelerate its domestic chip tool production, boosting firms like AMEC, ACM Research, and NAURA, which grew over 40% in 2024.
Conclusion: No More Free Pass—But at What Cost?
The U.S. risks tripping up allies while trying to outrun China in the chip race. Canceling waivers may feel like a power move, but it could open doors for China’s tech ecosystem to grow stronger, faster, and more independent.
This isn’t just about controlling chips. It’s about setting the pace for the future of technology—and deciding who gets to cross the finish line first.
