Summary

Semiconductors are strategic and uniquely important electronic devices. They are fundamental to most industrial and national security activities and serve as essential building blocks of other technologies, such as artificial intelligence (AI). Policymakers, including top leaders in the United States, the People's Republic of China (PRC, or China), and elsewhere, see semiconductors and AI technologies as critical to future economic competitiveness, national security, and global leadership. In 2014, the PRC government issued a national semiconductor industrial policy with the stated goal of establishing a world-leading semiconductor industry in all areas of the integrated circuit supply chain by 2030. To achieve its goals of technology leadership and independence, China has used government financing and certain policies to foster targeted foreign commercial ties across the semiconductor supply chain.

Since 2018, the U.S. government has sought to strengthen U.S. export controls of advanced semiconductors with the stated intent of both restricting PRC access to the technologies and ability to produce advanced chips, and curtailing PRC access to related computing and AI applications. U.S. actions have also sought to sustain U.S. leadership in advanced chips, related parts of the semiconductor supply chain, and computing and AI applications, while slowing China's development of competitive capabilities. U.S. actions have been grounded in concerns about PRC efforts to build an indigenous, self-sufficient, and secure and controllable semiconductor ecosystem; and PRC military-civil fusion policies that seek to use commercial advancements in semiconductors, AI, and other technologies for military uses. Some analysts have noted that before 2018, some U.S. controls and licensing policies vis-a-vis China allowed some U.S. firms across the supply chain to contribute to the development of China's semiconductor industry. U.S. efforts to enhance controls have restricted some advanced technologies and activities from China. Other parts of the semiconductor supply chain remain open to China.

Congress and the Trump Administration are assessing how to advance U.S. competitiveness in semiconductors and AI. In this context, some stakeholders have called for removing controls on advanced chips to promote U.S. competitiveness and possibly increase PRC entities' reliance on U.S. firms; others have said liberalizing controls could cede some U.S competitive advantages to China in part by filling PRC gaps in advanced chips. Some stakeholders have argued U.S. controls could encourage PRC efforts to indigenize technology. PRC policies already seek technology "self-reliance" and restrict foreign firms' market access as PRC firms gain technological capabilities. Some Members of Congress have raised concerns about President Trump's negotiation of U.S. export control terms with China and approval of Nvidia's H20 and AMD's MI308 for sale in China. Some former U.S. officials have expressed concerns about what they have described as negotiating national security decisions in exchange for trade concessions or government revenue, and have pointed out that such actions could be seen as contradicting past U.S. practice to reject PRC efforts to negotiate on such terms. Congress may assess the authority for the U.S. government to receive proceeds from licensed chip sales. Of potential relevance, depending on the facts as they continue to emerge, may be Article I, Section 9, Clause 5 of the U.S. Constitution, which prohibits the federal imposition of export taxes and duties (not user fees), and 50 U.S.C. §4815(c), which prohibits BIS from collecting fees for considering or issuing export licenses.

Introduction

Since 2018, the U.S. government has sought to strengthen U.S. export controls to restrict the PRC's access to advanced semiconductor ("chip") technologies and ability to produce advanced chips. U.S. actions have focused on sustaining the lead in advanced chips, and related computing and AI applications, and slowing China's development of competitive capabilities, including in defense and intelligence.1 The controls also sought to counter and slow PRC efforts to build an indigenous, self-sufficient, and secure and controllable semiconductor ecosystem and thwart PRC military-civil fusion policies that have sought to apply commercial advancements in semiconductors, AI, and other technologies for military purposes.2 Prior to 2018, U.S. controls and export licensing policies vis-a-vis China allowed firms across the semiconductor supply chain to sell a range of products and services in China.3 This activity provided revenue for U.S. firms. It also allowed China to develop some competitive capabilities.4 Parts of the supply chain that remain open to China include some advanced chips (through licensing) equipment and tools; third-party computing; mature-node technology; research and development (R&D) and open-source technology; materials and intermediates; and training for PRC staff. This report discusses U.S. export control actions related to advanced semiconductors, potential gaps, and issues before Congress. Text Box I describes the technologies discussed in the report; Table A-1 provides a timeline of U.S. export control actions.5

I: Advanced Semiconductor Chips and Supply Chains

Discussions of advanced semiconductors focus on a particular set of chips, specifically, advanced logic chips—including Field-Programmable Gate Arrays (FPGAs) and Application-Specific Integrated Circuits (ASICs)—advanced memory chips—including High-Band Memory (HBM) and Dynamic Random Access Memory (DRAM) chips, and graphic processing units (GPUs), which provide the speed and levels of computing power required to process vast amounts of data and perform complex calculations used in supercomputing and AI applications.6 Other parts of the advanced semiconductor supply chain include: a) design and intellectual property (IP); b) certain materials (e.g., metals, minerals, elements, chemicals, and gases); c) specialized processed inputs (e.g., photoresists and photomasks); d) specialized manufacturing processes (e.g., deposition, etching, and photolithography); e) semiconductor manufacturing equipment (SME); f) electronic design automation (EDA) hardware and software tools; and g) advanced packaging and testing techniques and tools that can enhance a chip's performance.7

Overview of U.S. Government Actions

The first Trump Administration expanded export controls on semiconductor technologies to China, mostly through an actor-based approach that added some PRC firms (e.g., Huawei) to the Commerce Department's Bureau of Industry and Security (BIS)' Entity List (EL). The EL lists foreign persons and entities who are involved, or have the potential to be involved, in activities contrary to U.S. national security or foreign policy interests. It requires licenses for exports of dual-use items (items with both commercial and military uses) listed on the Commerce Control List (CCL) and other items.8 In 2020, BIS expanded the foreign-produced direct product rule (FDPR) to subject any firm to U.S. export controls when using U.S. technology, software, or equipment to produce chips for Huawei.9 BIS also reconstituted its Military End User (MEU) list—a list of entities requiring licensing for exports, reexports, or transfers of specific dual-use items to the PRC, Russia and China because of risks of technology transfer for military use and retightened license requirements for PRC firms on the MEU.10 BIS had previously waived license requirements for dual-use exports to PRC military firms if the items were for non-military uses.

During the Biden Administration, BIS added more PRC entities to the EL and strengthened technology-based and country-based controls for advanced chips and related semiconductor manufacturing equipment (SME), such as SME using extreme ultraviolet lithography (EUV) and deep ultraviolet lithography (DUV). The U.S. government also negotiated terms with Japan and the Netherlands to align SME export controls vis-a-vis China.11 In 2022, BIS added controls on certain advanced logic chips, integrated circuits, and SME related to advanced computing.12 In 2023, BIS added PRC entities involved in advanced computing and AI to the EL.13 BIS closed gaps in controls for certain Nvidia chips designed for China that fell below earlier computing control thresholds and added details to SME controls.14 BIS also exempted some foreign-owned facilities in China that are not PRC-majority owned from certain controls. Also, in 2023, former President Biden issued Executive Order 14105, followed by an implementing rule in 2024, to restrict U.S. investment in advanced chips and certain types of AI in China.15 In 2024, BIS expanded the FDPR to apply to SME and chips and further restricted exports to 16 PRC entities.16 BIS added China wide-controls for advanced packaging SME, high-bandwidth memory (HBM), and dynamic random-access memory (DRAM), which, with the expansion of the FDPR, extended controls to South Korean firms operating in China.17 BIS added controls for "node-agnostic" tools (used for legacy and advanced chip production) and DUV and multi-patterning techniques. Other SME is subject to end-use/end-user controls and has a new license exception. BIS added 140 PRC entities to the EL and removed three PRC firms from the validated end-user program (VEU).18

On January 15, 2025, BIS issued a global AI Diffusion Rule to curtail PRC access to advanced chips and AI computing power through third countries and in an effort to create a secure global ecosystem for AI data centers.19 The rule proposed a global licensing framework that grouped countries into three categories for export controls on advanced chips, computers, and AI model weights. Tier I included the United States and 18 countries with whom the United States partners on intelligence, security, and semiconductors, and exempted them from licensing. Tier II included most other parts of the world; these countries would be licensed through a data center VEU program, which would operate under a presumption of license approval. The VEU program provided a general authorization for U.S. exports of advanced chips to pre-approved data centers. These countries also were subject to a per-company per-country cumulative total computing power allocation. Tier III included China, Russia and North Korea, which were subject to a presumption of denial.20 The rule also aimed to close gaps in controls by considering multichip modes and total computing power, and by restricting PRC access to third parties, including via cloud computing services. BIS also ended license exceptions for front-end chip fabricators and outsourced assembly and testing; and restricted PRC access to advanced U.S. AI model weights.21

The second Trump Administration to date has both tightened and loosened export controls on chips. Initial actions tightening controls have included adding 42 PRC entities to the EL; and requiring Nvidia to apply for a license to sell its H20 GPU in China.22 The H20 is the latest in a series of chips Nvidia modified in response to U.S. export controls (see Text Box II). Also, BIS assessed in May 2025 that Huawei had developed its Ascend chips in violation of U.S. controls and warned that using such chips would violate U.S. export controls.23 BIS also informed firms that produce electronic design automation (EDA) hardware and software tools that they would need a license for PRC sales.24Actions loosening controls have included rescinding the Biden Administration's AI Diffusion Rule, which ended proposed controls on PRC access to third-party computing centers, and issuing the AI Action Plan in July 2025, which promoted the U.S. export of "its full AI technology stack—hardware, models, software, applications, and standards—to countries that join America's AI alliance."25 Also, BIS reportedly withheld export control actions against China during U.S.-China tariff talks.26 In July 2025, BIS rescinded license requirements for EDA firms after the PRC agreed to resume licensing rare earth magnets for U.S. firms.27 In August 2025, BIS approved Nvidia's H20 and Advanced Micro Devices, Inc. (AMD)'s MI308 GPUs for sale in China under terms that the U.S. government would receive 15% of proceeds.28

Gaps, Workarounds, and Countermeasures

BIS's targeting controls on certain PRC entities, technology levels, and industry segments has left gaps in controls and enabled corporate workarounds. The EL's actor-based approach is limited to specific entities, of which only parts of the firm and named subsidiaries are listed.29 Some PRC firms have restructured around these EL-based controls. For example, in November 2020, Huawei sold its 5G business, Honor, to a PRC government consortium.30 Huawei reportedly transferred some of its R&D teams and advanced technology and design capabilities to the new entity.31 BIS did not list Honor on the EL—either as a Huawei subsidiary or affiliate, or under a new listing—allowing Honor to come out from under U.S. export controls and resume technology licensing and partnerships with U.S. and foreign firms.32 U.S. firms AMD and Nvidia have responded to controls by calibrating GPUs for China that fall just below control thresholds but still support AI development and advanced computing functions.33 Licensing guidance in some cases only restricts certain technologies and allows BIS discretion to approve dual-use exports on a case-by-case basis, such as BIS's approval of Nvidia's H20 and AMD's MI308 for export to China.34 Some critics have contended that BIS has been slow to list PRC firms, strengthen controls, and respond to workarounds to address White House concerns about PRC semiconductor policies since at least 2016.35 Also, BIS's process of developing controls takes time and may signal to firms that controls may be coming. BIS's issuance of general licenses after controls are in effect would allow some sales of the controlled technology to China to continue for certain periods of time. With such possible signaling of impending BIS actions, together with BIS' use of general licenses, PRC firms may then be able to stockpile SME and chips.36 Advanced packaging techniques, aimed at enhancing performance and competitiveness with leading-edge nodes, also may allow firms to circumvent controls by grouping multiple mature-node chips.37 U.S. joint ventures (JVs) and R&D in China have supported some PRC chip advancements.38 BIS "red flag" guidance obligates certain corporate due diligence but a "knowledge" standard limits the extent to which firms are liable for knowing the end use of their exports. Some Members of Congress criticized Nvidia for not stemming PRC circumvention via third markets.39

II: Nvidia's Modified Chips for China

In October 2022, after BIS controlled its A100 and H100 GPUs, Nvidia customized its A800 and H800 chips for China by reducing the NVLink interface (high-speed, low-latency GPU-to-GPU communication) from 600GB/s to 400GB/s. (PRC firm DeepSeek used the H800 in its AI language model). In November 2023, after BIS controlled the A800 and H800 chips, Nvidia announced H20, L20, and L2 chips for China. The H20 is a modified H100 chip that is optimized for AI inference and memory bandwidth. It has a reduced core count but uses HBM3 technology, which BIS restricted in 2024, that supports AI applications. The L20 is a modified AD102. The L2 is a modified AD104. In May 2025, after BIS controlled the H20, Nvidia announced a new R&D center in China and said it would further optimize the H20 and develop the B30 based on its Blackwell RTX Pro with multi-GPU scaling and GDDR7 memory instead of HBM3 (which is subject to BIS controls).

BIS has coordinated export controls with certain governments; differences in controls and licensing nevertheless exist. China has access to foreign-owned foundries in the PRC and Taiwan.40 PRC dual-use industrial policies complicate BIS's ability to implement controls by obfuscating military and civilian entities and functions, and by requiring firms in strategic sectors, including semiconductors, to use a PRC government-tied partner, raising risks of technology spillage.41 BIS has also faced challenges in inspecting licensed end users in China.42 The PRC government has used export controls on advanced manufacturing inputs (e.g., germanium, gallium, and rare earth magnets) and antitrust and other regulatory actions to retaliate against U.S. export controls.43 As U.S. and foreign firms have complied with PRC technology transfer requirements, the PRC has pressed to secure even more advanced technology. After the H20 was approved, the PRC raised security concerns about the chip and reportedly is also pressing to relax controls on HBM chips.44 China may use its purported security concerns about the H20 to press for technology disclosures and access to more advanced chips.45 Nvidia's CEO has said he plans to sell chips more advanced than the H20 to compete in China.46

Issues for Congress

Congress and the Trump Administration are assessing how to advance U.S. competitiveness in semiconductors and AI. In this context, some stakeholders have called for removing controls on advanced chips to promote U.S. competitiveness and possibly increase PRC entities' reliance on U.S. firms; others have said liberalizing controls could cede some U.S competitive advantages to China in part by filling PRC gaps in advanced chips.47 Some stakeholders have argued U.S. controls could encourage PRC efforts to indigenize technology. PRC policies already seek technology "self-reliance" and restrict foreign firms' market access as PRC firms gain technological capabilities.48 Some Members of Congress have raised concerns about President Trump's negotiation of U.S. export control terms with China and approval of Nvidia's H20 and AMD's MI308 for sale in China.49 Some former U.S. officials have expressed concerns about what they have described as negotiating national security decisions in exchange for trade concessions or government revenue, and have pointed out that such actions could be seen as contradicting past U.S. practice to reject PRC efforts to negotiate on such terms.50 Congress may assess the authority for the U.S. government to receive proceeds from licensed chip sales. Of potential relevance, depending on the facts as they continue to emerge, may be Article I, Section 9, Clause 5 of the U.S. Constitution, which prohibits the federal imposition of export taxes and duties (not user fees), and 50 U.S.C. §4815(c), which prohibits BIS from collecting fees for considering or issuing export licenses.

Congress could consider legislation barring profit sharing in exchange for licensing approval or permitting BIS to charge fees for such approvals; requiring quarterly BIS reports on classification determinations, licensing decisions, and export data; instructing BIS to issue the annual public reports it has traditionally published in the past on China trade, which it has not issued since 2022; codifying existing BIS rules; and directing BIS to report to Congress on PRC semiconductor advances, possibly including, for example, on how such progress may have been made with U.S. support and on the quality of such advances (e.g., the ability of PRC firms to produce chips at consistent quality and scale to meet PRC demand).51 Legislation related to semiconductor export controls introduced in the 119th Congress include H.R. 1316 passed the Senate in August 2025 to require BIS to report annually to Congress with specific licensing details; H.R. 3447/S. 1705 to require the Secretary of Commerce to issue standards for chip security mechanisms; H.R. 2683 to require remote access for export licensed trade; H.R. 1122 to control the export to China of some chip technology; S. 1053 and H.R. 2246 to restrict some semiconductor investments in China and PRC firms; and S. 1473 to create an export control whistleblower program.
