Winning the Next Phase of the Chip War

02.07.25 | 22 min read | Text by Ben Noon

Last year the Federation of American Scientists (FAS), Jordan Schneider (of ChinaTalk), Chris Miller (author of Chip War) and Noah Smith (of Noahpinion) hosted a call for ideas to address the U.S. chip shortage and Chinese competition. A handful of ideas were selected based on the feasibility of the idea and its and bipartisan nature. This memo is one of them.

Summary

  1. Danger Ahead: Until now, the U.S. semiconductor policy agenda focused on getting an edge over China in the production of advanced semiconductors. But now a potentially even more  substantial challenge looms. Possible Chinese dominance in so-called ‘legacy’ chips  essential for modern economic life could grant it unacceptable leverage over the United  States. This challenge will require tools far more disruptive than ever before considered by policymakers for the chip competition. 
  2. The Foot on America’s Economic Neck: Collecting offensive economic leverage lies at the  heart of Chinese leader Xi Jinping’s strategy. Chinese dominance in legacy chips could  enable Beijing’s bullying of the United States it has thus far reserved for U.S. allies. China’s  growing leverage over Washington may embolden Beijing to think it could attack Taiwan with  relative impunity. 
  3. Familiar Semiconductor Policy Tools Won’t Work Alone: China increasingly has access to  the tech it needs for its legacy ambitions (via stockpiling and indigenization), damaging  possible expanded export controls. And unfair Chinese trade practices could reduce the  benefits of subsidies, as it has for solar and critical minerals. 
  4. Learning to Love Trade Protection: Only when the U.S. market cannot access Chinese  chips will they have sufficient incentive to manufacture chips in third countries. Washington could either turn to tariffs or outright bans on Chinese chips. Washington has several options  to block China’s chips – AD/CVD, 337, ‘ICTS’, 5949, and 232. But the most powerful tool would be Section 301 of the Trade Act of 1974. 
  5. The Keys to Success: Trade measures will have to target Chinese chips contained within  other products, not just the chips themselves. The U.S. government’s clarity into global  supply chains will have to grow dramatically. Allied participation and knowledge-sharing  might be needed. The United States can ease enforcement of a chips trade war by  incentivizing private industry to share the burden of detecting violations of U.S. law.  

The Generational Leap in U.S. Chip Policy 

For five years, U.S. concerns over China’s semiconductor sector focused on its cutting-edge chip  production. The bipartisan instinct has been to mix restrictions on Chinese access to Western  technology and to fund manufacturing of advanced chips at home. It began with the Trump  administration’s sanctions against Chinese chip giants Fujian Jinhua, Huawei, and SMIC. The Biden administration’s October 2022 export controls on China’s advanced chipmakers and the CHIPS and Science Act crowned a new era of technology competition focused on the absolute bleeding edge.  

Fast forward to July 2024: Washington entered the next phase of the chip war.  

Biden administration concerns about legacy chips emerged subtly last summer from one-off statements from Commerce Secretary Gina Raimondo. Before long Team Biden began to formally investigate the issue in an industry survey. Then in May the administration doubled existing tariffs on Chinese-made chips from 25% to 50%. 

Congress is equally concerned. The bipartisan China Committee endorsed tariffs on Chinese legacy chips in its December 2023 economic report and in a January 2024 letter to the administration. China’s growing position in the production of mature-node chips took center stage in a Committee hearing in June 2024, where Committee Chair John Moolenaar called for “a reliable domestic supply of semiconductors outside the reach of the CCP”. 

This apparently sudden shift reflects the growth of the stakes in the U.S.-China chip competition over the past year: 

Despite the scale of the challenge, Washington has not yet decided on its strategy to take on the  problem. The best approach to the legacy challenge will be one that can prevent U.S. reliance on  Chinese-made chips to ensure China cannot capture decisive leverage over the U.S. economy.  Doing so will require using trade measures to reject Chinese chips from the U.S. altogether.  

Dominance Means Leverage 

China’s fast-rising position in the legacy chip industry threatens U.S. national security because it  would grant Beijing extraordinary strategic leverage over the United States. That would encourage Chinese economic coercion and even a war over Taiwan.  

2.1. Xi’s Plan for ‘Offensive Leverage’: Geoeconomics lies at the heart of Chinese leader Xi  Jinping’s international strategy. The strategy is to exploit foreign dependence on Chinese critical  supply chains to accomplish Beijing’s objectives abroad. 

Xi himself laid the foundation of this vision in a pair of speeches in 2020 in which he called for  economic “deterrence” over the rest of the world. He called for an economic “gravitational field”  to “benefit the formation of new advantages for participating in international competition and  cooperation”. China would achieve this by heightening “the dependent relationships of international  industrial chains on our country, to form a powerful countermeasure and deterrence capability  against external parties who artificially cut off supply”, according to Xi. 

The Chinese Communist Party’s 2021 Five-Year Plan enshrined these principles in Party jargon,  calling for a “powerful domestic market and strong-trading country” to “form a powerful gravitational  field for global production factors and resources”. This is often called the “dual circulation” strategy by outside observers. It could more usefully be  called “offensive leverage”

2.2. Beijing’s Bullying Could Come for Washington: Since Xi Jinping rose to power in 2012, China  has repeatedly demonstrated these geoeconomic principles by flashing its economic strength to accomplish strategic objectives. 

The list of examples of Chinese economic coercion is long. In 2010, China limited Japanese  purchases of rare-earth minerals over a Senkaku Islands dispute. Norwegian salmon rotted that  same year on Chinese docks in retaliation for dissident Liu Xiaobo winning the Nobel Peace Prize. In  2012, Philippine bananas also rotted over the Scarborough Shoal dispute. In 2016, Beijing conveyed its displeasure toward Seoul for agreeing to host U.S. missile defense systems by squeezing South  Korean auto sales in China and slashing Chinese tourism in the country. 

This bullying has not slowed since Xi unveiled his economic thinking in 2020. That year, China  embargoed Australian wine, barley, wheat, coal, fish, and other products after Canberra passed  laws to reduce foreign influence and called for an investigation into the origins of Covid-19.In 2021, China blocked imports of Lithuanian goods over the state opening a “Taiwanese Representative  Office”. In just the past month, Beijing has threatened French luxury brands, German car makers, and Spanish pork producers in retaliation for EU duties on Chinese electric vehicles. 

Washington faces less blatant coercion compared to its allies. True, China has targeted U.S. firms  such Micron over the past few years. But the scale and ambition of this bullying has never  approached what China has applied to the likes of Australia and Lithuania. This may be because  Beijing does not believe it yet maintains necessary leverage over Washington to brandish its  economic blade as it does toward smaller economies.  

China’s growing position in the legacy semiconductor market could change that. How would  Beijing’s behavior change if sales of the Ford F-150 relied on Beijing’s willingness to sell its semiconductors?  

2.3. Reliance Endangers Taiwan: Western European reliance on Russian energy was one factor (among many) that encouraged Vladimir Putin to believe he could invade Ukraine with relative impunity. Likewise, deepening U.S. dependence on China for strategic supply chains could make it  far more difficult to challenge Beijing on sensitive geopolitical issues.  

The United States already relies on China for other key inputs to its economy: generic  pharmaceuticals, critical minerals, solar panels, and printed circuit boards, among others. U.S.  reliance on Chinese-made legacy chips – the product at the heart of modern economic life – could be the crown jewel of Chinese geoeconomics. American economic reliance on China could embolden Xi Jinping to think he could attack Taiwan with tolerable penalty.  

The Case for Blocking China’s Chips 

Familiar semiconductor policy approaches – export controls and subsidies – are inadequate alone to prevent reliance on Chinese-made legacy chips. Washington and its allies will instead have to turn  to the old-fashioned, disruptive tools of trade defense in the face of a challenge of this scale.  

3.1. It’s Too Late for Export Controls: The crux of current U.S. semiconductor policy toward China  is to contain the growth of Chinese advanced chip production by limiting its access to exquisite  machine tools produced by the United States and its allies (often called the ‘restrict’ agenda). Without those tools, China will be unable to build the cutting-edge chips that enable AI and  advanced weapons.  

Why not do the same for legacy chips? Washington and its allies could grow its existing rules so that China could not purchase machines capable of manufacturing legacy chips from Western producers. 

The issue is that China increasingly already has the tools it needs for its legacy chip production, in two ways: 

Export controls may have worked for the legacy challenge five or ten years ago. It’s unlikely to work alone today. 

3.2. Chinese Trade Practices Undermine Subsidies: The second pillar of Washington  semiconductor strategy for the past couple of years has been what’s often called the ‘promote’  agenda. The United States is deploying $39 billion in subsidies through the 2022 CHIPS and Science  Act to incentivize new chip factories at home. The strategy has helped galvanize $447 billion in  private investment across 25 states, 37 new chip fabs, and expansions at 21 other fabs. The United  States is now projected to make 30% of all advanced logic chips by 2032. But the CHIPS and Science Act  focuses on advanced chips, not legacy ones. Only a quarter of CHIPS funding ($10 billion) is planned to be spent on legacy-chip production.

Why not pass a Chips Act for legacy chips? California Representative Ro Khanna has called for doing  so: “a Chips Act 2.0 and 3.0 to better focus on legacy chips for our cars, refrigerators, and dryers”.  Indeed, subsidies may be a key tool to spur additional domestic legacy chip  production.  

But subsidies alone are unlikely to rise to the challenge. China’s “brute force” economic strategy  might render a legacy ‘promote’ agenda stillborn.  Beijing’s approach is to eliminate foreign  competitors with low prices by flooding international markets with state-sponsored artificially high  supply. China could flood the market with cheap chips to deter private Western investment into new chip production despite generous subsidies. The result could be billions of taxpayer dollars spent  with insufficient new chip capacity to show for it. 

Two recent examples demonstrate how Chinese industrial policy practices can undermine  Washington ‘promote’ policy: 

One Pentagon-funded Idaho mine, the only cobalt mine in the United States, was planned to open last year. It’s instead been mothballed since over low cobalt prices – down by almost two-thirds in two years.The  owner of that mine, Australian firm Jervois, told investors in March it would lay off 30% of its senior corporate management over “adverse cobalt market conditions caused by Chinese  overproduction and its impact on pricing”.

The warning signs in the legacy chip sector are already flashing. Chinese semiconductors were “20  to more than 30%” cheaper than their international counterparts in 2022 and 2023, according to the  Silverado Policy Accelerator.This price advantage will likely only widen with time. 

3.3. Don’t Compete with China on Price: The challenge facing U.S. policymakers is that Chinese  industrial policy is designed to make it impossible for Western firms to offer prices competitive  against Chinese players. The solution is to deny Chinese chips access to Western markets.  

The logic is simple yet unfamiliar for some following semiconductor policy. Only if the U.S. market is denied to Chinese chips will those producing for the United States be forced to source chips outside  of China, and only then will the construction of scaled chipmaking capacity in third countries  become economic.  

How It Would Work 

Preventing U.S. reliance on Chinese chips would be more complicated than simply raising the tariff  on Chinese-made chips imported into the U.S. market. For it to work, Washington would need to  target goods that contain Chinese chips, not just the imports of the chips themselves. It also may need allied cooperation.  

4.1. Target Chips as Components, not the Chips Themselves: Semiconductors are  overwhelmingly an intermediate good, not a final product of the sort Washington typically tariffs or blocks at the border. U.S. policy will have to reflect that complexity.  

The Biden administration in May doubled U.S. tariffs on imported Chinese chips from 25% to 50%,  citing China’s “rapid capacity expansion that risks driving out investment by market-driven firms”. The original 25% tariff, imposed by the Trump administration in 2018, reduced direct imports of  Chinese chips by around 72%, according to the U.S. International Trade Commission. But direct  imports represent only a portion – likely a minority portion – of the Chinese-made chips that  otherwise enter the United States as components within other devices. 

The original 2018 tariffs had no effect on Chinese chips arriving as components of other goods – and  neither will the new Biden tariffs, which double the rate of the 2018 tariffs without changing their design. Closing this loophole would require the administration to do just that.  

One way of doing so would be to apply a “component tariff”, effectively increasing the import cost of  the final good (whatever it is) because it contains a chip or chips made in China. The China Committee called for this in January 2024. Another way would be to deny outright products containing Chinese chips entry into the United States. Both options could work, assuming a component tariff is  high enough to overcome any possible Chinese price advantage (e.g., 200% or higher).  

Some experts have expressed doubt that it is even possible as a policy matter to target Chinese chips  because they are intermediate goods. But this view is erroneous. In fact, various laws allow  Washington to tariff or outright exclude from the U.S. market any product made with Chinese  semiconductors. (See Section 5). 

4.2. Bring the Allies Along: A strategy to prevent U.S. reliance on Chinese chips would have higher  odds of success if U.S. allies join, most importantly Europe and Japan. The risk is that without allies,  international chip players would continue to design their microelectronics with Chinese chips, leaving the United States out of the best the market has to offer. A more optimistic assessment would be that the U.S. consumer market is so large that unilateral Washington action would be  enough to force leading market players to design their products without Chinese chips. 

Either way, allied signals are positive. The EU said about legacy chips last  April that it was “gathering  information on this issue”, and that it would coordinate with the United States to “collect and share  non-confidential information” about Chinese “non-market policies and practices”.The bloc’s new  duties on Chinese automakers indicate it could be open to similar measures toward chips. Japan  has taken fewer concrete steps than Europe, but Tokyo’s Minister for Economy, Trade and Industry Ken Saito told reporters that participants took “great interest” in legacy chips at the first Japan Korea-U.S. Commerce and Industry Ministerial Meeting on 28 June 2024

Washington’s Toolkit 

The United States has multiple policy tools that could be used to prevent U.S. reliance on Chinese made semiconductors. Th following summarizes these tools, in roughly ascending order of magnitude.  

5.1. Countervailing Duties: This form of tax can be placed by the Commerce Department on foreign goods that it finds to be subsidised and that the U.S. International Trade Commission (ITC) finds  materially injure a U.S. domestic industry. After an investigation prompted either by a petition from U.S. industry or initiated by Commerce itself, Commerce can impose “CVDs” on the goods in  question

Two challenges, however: First, it can sometimes be difficult to prove that Chinese state subsidies  have boosted specific goods. Second, chips imported as components of other goods aren’t a natural  fit for CVD investigations, so some policy creativity would likely be required

5.2. Anti-Dumping Duties: This alternative tax is like its sister duty in how it comes about and who  investigates it, but in this case it seeks to counter imports that have been “dumped” at artificially low prices in the U.S. market. 

As with CVDs, however, some policy creativity may be required to use anti-dumping duties for chips  imported as components of other goods. Further, it can be challenging to establish a baseline “fair”  price against which to measure the price of any Chinese goods in the U.S. market. Former senior Commerce official Nazak Nikakhtar noted: “It is nearly impossible to find a surrogate  country that has not been adversely affected by the PRC’s predatory pricing. . . . Virtually all  benchmark prices in trade cases are now understated and inadequate for measuring [dumping] by the PRC.” 

5.3. Section 337: This provision (from the Tariff Act of 1930) allows the U.S. ITC to investigate  imported goods for alleged links to intellectual-property theft and a range of other unfair trade  practices. Relief can take the form of exclusion orders, cease-and-desist orders, or sequestration of goods.  

But the 337’s bureaucratic process might be too burdensome. The ITC is an independent agency not subject to direction by the White House. In 2018, the Commission on the Theft of American  Intellectual Property, led by ex-ambassador and ex-governor Jon Huntsman, recommended speeding up the ITC’s 337 process.

5.4. Section 5949: With relatively little fanfare, Congress in late 2022 enacted a measure that will  curb some Chinese legacy-chip sales in the U.S. market – but only some, and slowly. Via Section  5949 of the annual defence bill, Congress prohibited the U.S. federal government and its contractors  from procuring semiconductors for “critical” uses from three Chinese firms (SMIC, YMTC, CXMT),  beginning in four years. This provision could be expanded in multiple ways that would block Chinese chips from large swathes of the U.S. market. Policymakers could shorten the phase-in period, blacklist additional companies (beside SMIC, YMTC and CXMT), or force U.S. government  contractors not to buy proscribed Chinese chips even for their own private use.

The federal government does not, however, have the authority to force state governments to adopt similar rules. This approach would also allow any company that does not contract with the federal  government to purchase Chinese chips.  

5.5. ‘ICTS’: The Commerce Department’s “Information and Communications Technology and  Services” (ICTS) regime is probably capable of restricting the import of goods containing Chinese made chips. The regime, first outlined in the final days of the Trump administration and embraced by  the Biden administration, has broad authorities to restrict transactions (from limits on cross-border  data flows to import bans) across theoretically the entire digital economy: critical infrastructure,  network infrastructure, data hosting, surveillance and monitoring tech, communications software, and emerging technology.The ICTS office’s current investigation on Chinese ‘Connected Vehicles’, will restrict Chinese-controlled critical components from being used in cars on U.S. roads. The  president might similarly be able to use ICTS to restrict the import of products containing Chinese made semiconductors.  

Taking on Chinese legacy chips, however, would not fit the ICTS Office neatly:

5.6. Section 232: This instrument (from the Trade Expansion Act of 1962) allows any federal  department to require a Commerce Department investigation of specified imports that may threaten  national security (defined broadly). The President may then impose tariffs or quotas as a remedy.  The Trump administration used Section 232 to tariff imports of steel and aluminum in 2018, and it  could be a viable approach to legacy chips too.  

232’s main drawback is that it does not allow import bans. An obvious workaround would be to apply a component tariff onto Chinese semiconductors so high that it works effectively as a ban (e.g., north  of 200%).  

5.7. Washington’s Most Powerful Tool – Section 301: The strongest tool for the legacy-chips  challenge might be the Section 301 of the Trade Act of 1974, which gives the Office of the U.S. Trade  Representative broad scope investigate “unreasonable”, “discriminatory”, or  “unjustifiable” actions that burden U.S. commerce.  After an investigation, USTR has sweeping  powers to impose remedies as it sees fit, e.g. with tariffs, import bans, or other sanctions. It gives a president notably broad, flexible, and discretionary powers. 

301 has become the bipartisan tool of choice to address unfair Chinese trade and industrial practices and to reshore supply chains: 

A future 301 investigation could almost certainly find a way to prohibit goods with Chinese-made semiconductors from entering the U.S. market. The United States could open a 301 investigation into  Beijing’s state-led subsidy strategy to do so, as the Biden administration considered doing in 2021

Some may worry that 301’s required investigation before applying remedies would slow down a  solution that would ideally begin as soon as possible. But a public investigation of China’s position in the semiconductor industry could have major benefits. It could provide the administration insight into the international microelectronics supply chain, needed to implement a legacy restriction policy. 

And it would send industry a clear message that it should begin shifting its supply chains before the new U.S. policy began.  

Some of History’s Lessons on Decoupling  

One challenge facing this strategy is if it is practically possible to stop Chinese-made chips from  entering the U.S. market, no matter U.S. law. Some have called banning Chinese chips tantamount to trying to “hold sand in your hands”. The U.S. government has limited visibility into global supply chains. How could Washington enforce the next phase of China chips containment? 

Two examples of U.S. efforts to remove goods from international supply chains point to lessons about how the United States could go about doing so successfully today: implementation of the  Uyghur Forced Labor Prevention Act (UFLPA), and the ‘Kimberley Process’ to prevent sourcing blood  diamonds from Africa. They show that Washington will need three things to enforce this strategy: supply chain clarity, active participation from private industry to detect lawbreakers, and an allied  coalition to ensure success in preventing U.S. reliance on Chinese-made chips.  

6.1. Improving on the UFLPA Enforcement: Removing Chinese-made legacy chips from the U.S.  market would not be the first time Washington moved to fundamentally change the U.S.-China  trading relationship in pursuit of excising specific Chinese goods from the United States. The Uyghur Forced Labor Prevention Act, passed by Congress in late 2021, prohibited entirely any goods from  Xinjiang – or those with supply chains stemming from there – from coming into the United States on  grounds that they were tainted with forced labor. UFLPA Republican co-author Marco Rubio vowed  in 2021 that it would “fundamentally change our relationship with Beijing”. Jim McGovern, the  Democratic congressman who authored the House version of the bill, said “No more business as  usual”. 

Yet the law has had a less significant impact on U.S.-China trade flows than initially anticipated, most importantly in the solar industry. Some half of all global polysilicon, a base material for solar panels, comes from Xinjiang. Chinese firms have nonetheless increased their market share in the  United States since the passage of the UFLPA

There are three lessons to take from these challenges that policymakers can apply to the coming legacy chip trade war: 

  1. Supply Chain Clarity Needed: The UFLPA granted the administration no additional funding  for enforcement, likely forcing difficult decisions across the administration of how to fund  the stiff demands for research into global forced labor supply chains. Enforcing legacy-chip  protectionism would likely require a major expansion of supply chain analytical capabilities  across the U.S. government, including in the Commerce Department and within Customs  and Border Protection. 
  2. Let Private Industry Help with Enforcement: UFLPA enforcement might have been more  successful if detecting those who violated U.S. law was the responsibility of private industry,  not that of the government. Is this even possible?  


It appears so. The False Claims Act of 1863 allows private parties to initiate a lawsuit on  behalf of the U.S. government against those who have defrauded the U.S. government. Whistleblowers receive some 15% to 30% of the government’s award if they win. This law,  originally passed in the Civil War to crack down on fraud from military contractors, has  increasingly been used against those who commit customs and tariffs fraud. The law triples damages and civil penalties for violators.  

These cases (called “qui tam” cases) have been brought against those who transshipped  Chinese goods through third countries to dodge 301 tariffs. In one case, manufacturing  tools firm King Kong Tools paid $1.9 million in November 2023 to settle allegations that the  firm dodged paying 301 tariffs by falsely claiming its goods were made in Germany. The  case began when a competitor to King Kong brought a qui tam suit alleging that King Kong  produced its products in China, shipped them to Germany, then sent them to the United  States. The whistleblower received an award of $286,000

Washington could similarly enlist the private sector to help detect violations of legacy-chip trade rules. At a minimum, the Justice Department could begin a public campaign to  encourage whistleblowers to bring qui tam cases against violators. (Including technology research firms. TechInsights, the company known for teardowns of Chinese  microelectronics to determine their quality, comes to mind here.) The U.S. government  could also find ways to increase the incentive for private parties to bring cases against tariff  dodgers. Congress could update the False Claims Act to boost the reward for whistleblowers,  for example.  

6.2. An Allied System for Legacy-Chip Trade Protection: The Kimberley Process is a UN-mandated  certification scheme launched in 2003 to prevent diamonds that fund conflict from entering global  markets. 85 member states, civil society groups, and industry agreed to commit to transparent  practices and share data to certify that imported diamonds are not tainted by conflict. 

Washington and its allies should agree to collectively work to restrict the import of Chinese made legacy chips. They could share best practices and supply chain intelligence. It could make it  easier for Washington to know where Chinese semiconductors are moving throughout global supply chains. Doing so would help build an allied coalition collectively more resilient against Beijing’s economic coercion.
