Three independent EAR levers replace what would have been the AI Diffusion Rule's three-tier country framework:
1. GP10 + ECCN 3A090 (Huawei Ascend track). The guidance states that all 3A090 ICs designed by firms headquartered in the PRC — wherever fabricated — are likely subject to the EAR and likely produced in violation of US export controls. That triggers GP10, which prohibits any US or non-US person from selling, transferring, financing, transporting, or servicing an item known to have been produced in violation of the EAR. Huawei Ascend 910B, 910C, and 910D are named as presumptively-covered models. The reach is extra-territorial: a non-US data centre running Ascend chips for inference is a presumptive GP10 violator.
2. AI training / inference policy statement. BIS's policy statement asserts that providing US-origin advanced computing ICs (including the 3A090 set) for training or inference of advanced AI models in support of Chinese end-users risks an EAR violation under existing end-use / end-user controls. This is the substantive replacement for ECCN 4E091 (the AI Diffusion Rule's model-weight control), achieved without a new ECCN.
3. Diversion-diligence industry guidance. A standalone guidance document specifying red-flag indicators and expected diligence steps (front companies, freight forwarders, secondary distributors, cloud-compute intermediaries). Aligns with the "high probability" enforcement posture BIS signalled in parallel public statements.
The package leaves the underlying export-control statutes and existing 3A090 thresholds untouched — it changes enforcement interpretation, not rule text.
Ascend 910B/910C/910D are now globally radioactive for any buyer wanting to transact with US-linked counterparties. Western cloud + AI infrastructure customers cannot run Ascend without a presumptive GP10 violation. Practical effect: forces a hard split between China-domestic Ascend deployments and ROW NVDA/AMD deployments.
Diffusion Rule's hard country caps. Net effect for Tier-2 destinations (UAE, Saudi Arabia, India, Singapore, Israel) is a permissive shift relative to what would have been Jan-2025 caps; bilateral G42-style deals fill the authorisation pathway. Hyperscaler VEU pathway is gone.
the structured VEU pathway but gain flexibility on ROW data-centre buildout. Must implement diversion- diligence programmes per guidance #3.
enforcement frontier. The "designed by PRC-headquartered firms" framing reaches Ascend wafers fabricated outside China, tightening the trilateral perimeter without new rule text.
Federal Register rescission notice and replacement rule are the next-shoe-to-drop. Until then, the Jan-2025 rule formally remained on the books with compliance dates of 15 May 2025 and 15 January 2026 — though enforcement posture is non-enforcement per the press release.
publish, and does it carry a replacement rule with it?
challenged? Foreign-designed-and-fabricated chips have thin precedent for being EAR-subject.
expand to non-PRC end users (e.g. UAE, Saudi labs running open-weight models with PRC fine-tunes)?
interact with traditional knowledge-based EAR enforcement in actual prosecutions?
