Why did H20 need a U.S. license even though Nvidia designed it for China?
H20 was designed after BIS tightened its 2023 rules and removed the interconnect-bandwidth test that earlier China-specific Nvidia products had relied on. That design did not secure a permanent safe harbor. In April 2025, the United States required licenses for H20 exports and for chips meeting the specified memory or interconnect-bandwidth criteria. For a prospective H20 buyer or seller, the relevant check is the current license rule, not whether the product was originally engineered to fit an earlier threshold.

US imposes a license requirement on Nvidia A100 and H100 exports to China
Nvidia disclosed that the U.S. government had imposed, effective immediately, a license requirement for exports of its A100 and forthcoming H100 chips to China, including Hong Kong, and Russia, along with systems containing them and any future chip at A100-level performance. Nvidia said it did not sell to Russia and that the rule could affect H100 development and A100 support.

Why it matters here. The A100 and H100 China license requirement was followed by BIS's October 2022 rules imposing advanced-computing controls generally on China.

BIS publishes the October 2022 rules on advanced computing chips and chipmaking tools for China
The Bureau of Industry and Security issued a package of export controls restricting advanced computing chips, supercomputer and semiconductor end uses, and chipmaking equipment for China. The advanced computing and supercomputer controls took effect on October 21, 2022, turning the company-specific August letter into a general rule.

Why it matters here. BIS turned the initial Nvidia-specific restriction into general advanced-computing rules for China, which it tightened again in 2023 by removing interconnect bandwidth as a control parameter.

BIS tightens the chip rules, dropping the interconnect-bandwidth test that A800 and H800 were built around
BIS released updated rules on advanced computing chips and chipmaking equipment. Among the changes it removed interconnect bandwidth as a parameter for identifying restricted chips, which brought Nvidia's China-specific A800 and H800 within the controls, and extended license requirements to more countries. Nvidia's same-day filing listed A100, A800, H100, H800, L40, L40S and RTX 4090 as covered.

Based on public comments, recent technological developments, and analysis of the prior rule's national security impact, the AC/S IFR removes 'interconnect bandwidth' as a parameter for identifying restricted chips.
Why it matters here. By removing the interconnect-bandwidth parameter and bringing A800 and H800 within the controls, BIS prompted Nvidia to prepare H20, L20, and L2 parts designed to fit the October 2023 limits.

US requires a license for H20 exports to China; Nvidia flags up to US$5.5 billion in charges
Nvidia disclosed that on April 9 the government required a license for exports of H20 and any chip with its memory or interconnect bandwidth to China, Hong Kong, Macau and D:5 countries, and on April 14 said the requirement would apply indefinitely. Nvidia expected up to about US$5.5 billion of first-quarter charges for H20 inventory, purchase commitments and reserves.

Nvidia takes a US$4.5 billion H20 charge, loses US$2.5 billion in shipments, expects US$8 billion hit next quarter
In first-quarter fiscal 2026 results Nvidia recorded a US$4.5 billion charge for H20 excess inventory and purchase obligations, said it could not ship a further US$2.5 billion of H20 revenue, and guided second-quarter revenue of US$45 billion reflecting about US$8 billion of lost H20 revenue.
Nvidia Newsroom ·
NVIDIA incurred a $4.5 billion charge in the first quarter of fiscal 2026 associated with H20 excess inventory and purchase obligations as the demand for H20 diminished.
Why it matters here. The licence requirement stopped being a policy question at that point and became a write-down: US$4.5 billion, plus revenue Nvidia could not ship.

Reports say Nvidia is preparing H20, L20 and L2 chips that fit under the new China limits
The Register, citing Chinese outlet Chinastarmarket and supply chain sources, reported that Nvidia was working on three GPUs for China, the H20, L20 and L2, engineered to stay below the performance thresholds in the October 2023 rules, with an announcement possible as early as November 16.

What it pushes against. Nvidia responded by preparing H20, L20, and L2 parts engineered for the new limits, a product-design workaround that initially pushed against further licensing.
