What the Revival of H20 Exports from the US to China Means

How does this chip ban reversal affect NVIDIA, Huawei, TSMC, BBATs

Hi all, it’s Grace here. I know I’ve been procrastinating on a few timely matters, so I apologize. There have been headlines flying everywhere on NVIDIA’s H20 chip ban being reversed. But what are the real implications? Let’s take a look today.

Almost two weeks ago, NVIDIA confirmed it will resume sales of its H20 AI chips to China, marking a sharp reversal of U.S. export restrictions. This abrupt policy shift ends a three-month freeze that had left China’s AI ecosystem scrambling—and signals a pivotal moment in the U.S.-China tech rivalry.

If you've been following my previous pieces on China’s AI push—from the DeepSeek frenzy to the robotics surge—you know this isn’t just chip news. This marks a pivotal moment for the entire AI value chain. In this post, I’ll unpack the implications from three angles: NVIDIA’s rebound, Big Tech’s relief, and domestic players’ recalibration.

With that…

What Did the H20 Ban Mean?

The H20 is a scaled-down version of NVIDIA’s Hopper chips—purpose-built to meet U.S. export controls, yet still powerful enough for training and inference work inside China.

Washington initially blocked the H20 over national security concerns, fearing the chips would turbocharge China's AI advancements. That decision cost NVIDIA an estimated $10–15 billion in potential annual sales and forced it to write down $4.5 billion in inventory that was stuck in limbo.

Let’s Talk Capex

Morgan Stanley’s most recent report still projects China will spend around RMB 380 billion (~USD 52 billion) on AI infrastructure in 2025, with upside if supply bottlenecks ease. This H20 unban clears the biggest roadblock to accelerating mass-market GenAI rollouts, especially with apps like ByteDance’s Doubao and Tencent’s Yuanbao, AI-native interfaces, and cloud-based upgrades.

According to Morgan Stanley’s latest report, China AI: Reviving a Giant with H2O Chip Availability, China's capital expenditure (capex) trajectory is now aligned with NVIDIA’s own $50 billion revenue opportunity from AI accelerators in the region.

In short, as long as Chinese AI demand remains deployment-focused, then embedding LLMs into apps, services, and use cases will only increase the appetite for GPUs, and that hunger will not just persist but likely grow.

Big Tech’s Relief

For China’s tech giants, the BBAT—ByteDance, Alibaba, Tencent, and Baidu—the H20’s return is a godsend. These four accounted for roughly 80% of H20 shipments in 2024 and reportedly had over 1.1 million chips on order for 2025 before the ban hit. Many reports stated that insiders were concerned about the GPU constraints, which were considered the biggest bottleneck for further LLM development.

Now that the freeze is lifted, those plans are back in motion—along with cloud deployments, LLM training, and product timelines that had been stalled or derailed.

Semi Supply Chain Winners

This is also a tailwind for Asia’s hardware ecosystem.

During TSMC’s Q2 2025 earnings call, Chairman Dr. C.C. Wei called the H20 resumption “positive news,” and Morgan Stanley expects TSMC to beat its 45% CAGR target for AI semiconductor revenues over the next five years.

Samsung, too, stands to benefit: it had previously taken a ₩1.5 trillion (~$1.1 billion) write-off in Q2 due to the H20 ban. With sales back online, this loss may partially reverse. Samsung also remains a key GDDR7 memory supplier for NVIDIA’s RTX Pro series.

Component and server makers like Wistron, FII, KYEC, Auras, and Unimicron should also see demand rebound as GPU-related projects resume.

Domestic Hardware’s Short-Term Setback

However, it’s not all good news, at least probably not for Huawei, as we’ve written about how Huawei was initially poised to benefit the most from an H20 ban, given that the BBATs had no other viable option.

Ironically, while Jensen Huang recently called Huawei “formidable,” Huawei founder Ren Zhengfei has repeatedly admitted that their chips are still one to two generations behind. This unusual PR tactic, where NVIDIA hyped up Huawei while Huawei downplayed itself, was likely a combination of lobbying and expectation management.

The short H20 ban window gave Huawei and GPU foundry SMIC a temporary boost. However, domestic GPU vendors may now lose that incremental share to NVIDIA again.

That said, this is not a reason for Chinese firms to abandon self-reliance. What it will likely do is simply buy them time. As Huawei’s own leadership has said, the long game is still domestic.

NVIDIA’s Revenue Snapback

NVIDIA pegs China as a $50 billion market opportunity. With the H20 back, analysts expect it could recapture $10–15 billion in AI chip sales in 2025, including a backlog of $10.5 billion worth of demand per Bernstein estimates.

The catch? Every H20 unit still needs individual export licensing. There are over 1 million H20s in inventory or production, so timing will depend on how fast these licenses can be cleared.

NVIDIA’s CFO recently noted that shipments may resume in the company’s fiscal Q3, meaning revenue is expected to start trickling in then. But in the long term, China could again resume being a low-teens percentage of NVIDIA’s revenue mix.

(Oh, how Jensen’s probably so happy as all those 14-hour flights and press meetings under the scorching sun in Beijing wearing a leather jacket paid off.. And don’t forget, when he was asked what American firms have that others don’t? He said - President Donald Trump.)

Final Thoughts

The H20 ban lift gives NVIDIA a vital tailwind, re-energizes China’s AI giants, and temporarily relieves domestic pressure on Huawei.

However, this episode also highlights a broader truth: every GPU shipment now passes through a gauntlet of diplomacy and export controls. In this U.S.-China tango, nothing is guaranteed. (As there are a few unstable personalities involved, it seems)

And while NVIDIA may have regained access, the strategic plan in Beijing hasn’t changed. AI deployment comes first. And the push for indigenous innovation continues, just with a little more breathing room.
