US-China Chip Decoupling – A Due Diligence Guide for Overseas Businesses Navigating the New Landscape
The global semiconductor industry has entered what analysts call an era of “managed decoupling” — a state where the world’s two largest economies are neither fully integrated nor completely severed, but instead navigating a complex web of export controls, domestic substitution mandates, and shifting supply chains. For overseas businesses with operations, suppliers, or customers in China, this new landscape demands a fundamentally different approach to due diligence. Understanding the structural gaps between the US and Chinese chip industries — and how those gaps are being reshaped by policy — is no longer optional. It is a compliance imperative.
1. Five Core Dimensions of the US-China Chip Gap
The competitive gap between the US and Chinese semiconductor industries is not a single metric — it manifests across five interconnected dimensions. Together, they explain why the US holds 94% of global computing chip supply while China holds just 6%, and why that gap is both a source of tension and a driver of change.
China: Huawei CANN — open-sourced in 2025, approximately 8 years of development, still maturing in usability and toolchain depth.
China: SMIC at 7nm-class; ~2-3 generation gap; EUV lithography still at prototype stage.
China TOP5: ~$2.3 billion annually — a ~20x gap in absolute R&D spending.
China: Largely internal consumption within cloud providers (Alibaba, Baidu) and government procurement.
China: ~300 chip architects estimated, talent gap of 18,000 etching equipment technicians and 30,000 chip design architects over next four years; university curricula often “theory-heavy, engineering-light”.
2. The Export Control Timeline — From A100 to H200 and Beyond
US export controls have evolved through three major phases since October 2022, each progressively tightening the technological ceiling for chips that can be sold to China.
First phase: Biden administration bars exports of advanced semiconductors (A100, H100) and chipmaking equipment to China.
Second phase: Curbs expanded to cover A800, H800, and L40S — chips specifically designed to comply with earlier restrictions; licensing requirements tightened for exports to more than 40 countries.
Foreign Direct Product Rule expansion: Any item shipped to China containing US chips, regardless of where it was manufactured, now subject to controls.
Third phase — case-by-case review: BIS shifts from “presumption of denial” to case-by-case licensing for NVIDIA H200, AMD MI325X, and equivalent chips. Eligible chips must have TPP < 21,000 and DRAM bandwidth < 6,500 GB/s. Conditions include 25% revenue tariff, 50% volume cap, mandatory US testing, and KYC certification.
Chip Security Act (H.R.3447): US House Foreign Affairs Committee passes bill marking shift from “license management” to “technology monitoring”.
Third round of curbs imminent: Commerce Department official warns new AI and semiconductor regulations are coming — potentially the third major expansion since 2022.
The result is a tiered global AI ecosystem. The H200 is permitted (with onerous conditions); the more advanced Blackwell B200 and Rubin R100 remain strictly prohibited. As of May 2026, despite US approval for approximately 10 Chinese companies to purchase H200 chips, not a single unit had been shipped — Chinese buyers are increasingly opting for domestic alternatives.
3. Who Benefits, Who Feels the Pressure
📈 Benefiting — The Domestic Champions
Huawei is the primary beneficiary. The company plans to double production of its Ascend 910C AI chips in 2026 to approximately 600,000 units, with total die production across the lineup reaching 1.6 million. Huawei is also targeting shipment of approximately 750,000 of its new-generation 950PR chips in 2026. Cambricon, Alibaba T-Head, and Baidu Kunlunxin are also capturing market share. Domestic manufacturers now hold 41% of China’s AI accelerator server market.
At the policy level, China is drafting a ¥2 trillion ($295 billion) plan to build a national AI data centre grid, with at least 80% of underlying technology to be sourced domestically — effectively excluding NVIDIA and AMD from one of the world’s largest infrastructure projects.
📉 Feeling the Pressure — NVIDIA and the US Ecosystem
NVIDIA is the biggest loser in this standoff. At its peak, the company controlled 95% of China’s high-end chip market, with China accounting for 13% of total revenue. Since export controls tightened, NVIDIA’s China revenue fell 21.2% year-over-year in fiscal 2025. CEO Jensen Huang has acknowledged that NVIDIA’s share of China’s AI chip market has “effectively collapsed to zero”.
The H200 approval was meant to stem that decline — but the 25% US revenue “Trump Cut” has halved NVIDIA’s gross margin on these sales, while Chinese buyers remain reluctant. The broader US semiconductor industry faces headwinds: the CHIPS Act continues to fund domestic fabrication, but the three largest US chipmakers (NVIDIA, AMD, Intel) together derive roughly 25% of sales from China and other restricted markets.
4. Supply Chain Due Diligence — New Dimensions for Overseas Businesses
The decoupling landscape requires overseas businesses to ask new questions about their Chinese partners and suppliers. Here are the key dimensions to include in your due diligence framework.
- Chip source and origin verification. Does your Chinese partner use US-origin chips (NVIDIA, AMD, Intel) or domestic alternatives (Huawei Ascend, Cambricon, T-Head)? With US export controls tightening, the origin of chips matters for compliance — not just for your partner, but potentially for your own downstream obligations.
- Technology licensing and IP dependencies. Does your Chinese partner rely on US-licensed IP, EDA tools, or manufacturing equipment? The Foreign Direct Product Rule means that even products manufactured outside the US may be subject to controls if they contain US technology.
- Entity List and sanction exposure. Has your Chinese partner — or any of its subsidiaries or affiliates — been added to the US Entity List? Since 2022, BIS has added more than 150 Chinese entities to the list. New legislation in 2026 specifically targets companies including CXMT, Hua Hong, Huawei, SMIC, and AMEC.
- Domestic substitution compliance. Is your Chinese partner in compliance with China’s domestic procurement mandates? State-funded data centres must now source at least 50% of chips locally, with some projects required to reach 80% domestic content. Non-compliance could affect your partner’s ability to fulfil contracts.
- Supply chain resilience and contingency planning. What happens if your partner’s chip supply is disrupted by further export controls? Are they diversified across multiple suppliers, or heavily reliant on a single source? The answer affects your own supply chain risk.
🔍 Know your Chinese partners — in a decoupling world. The rapid pace of US-China chip decoupling means that relying on outdated information about your Chinese counterparts is increasingly risky. Whether you need to verify a company’s business registration, check for legal disputes, or obtain an official credit report, having access to authoritative, up-to-date Chinese corporate records is indispensable.

Final Take — A New Due Diligence Imperative
The US-China chip decoupling is not a temporary disruption — it is a structural shift. The five gaps between the US and Chinese chip industries — ecosystem, process technology, R&D investment, commercial scale, and talent — are being reshaped by policy on both sides of the Pacific. Export controls have evolved through three phases, with a fourth potentially imminent. Chinese domestic champions are scaling rapidly, while US incumbents face shrinking access to the world’s second-largest market.
For overseas businesses, this new landscape demands a new approach to due diligence. Chip source verification, technology licensing review, Entity List screening, and domestic substitution compliance are no longer niche concerns — they are core elements of supply chain risk management. The companies that build these capabilities now will be the ones that navigate the decoupling era successfully.
