A House China Committee letter pushed BIS to clarify advanced-chip foundry due diligence.
Tom's Hardware reported that Representative John Moolenaar asked the Bureau of Industry and Security to clarify that the Foundry Due Diligence Rule remains in effect. The committee's August 10 release said ambiguity after the AI Diffusion Rule rollback could let advanced dies move through designers outside China without the due diligence BIS previously required. The underlying Federal Register rule says BIS revised export rules to add due-diligence procedures for advanced computing integrated circuits.

What happened
Tom's Hardware reported that Representative John Moolenaar asked the Bureau of Industry and Security to clarify that the Foundry Due Diligence Rule remains in effect. The committee's August 10 release said ambiguity after the AI Diffusion Rule rollback could let advanced dies move through designers outside China without the due diligence BIS previously required. The underlying Federal Register rule says BIS revised export rules to add due-diligence procedures for advanced computing integrated circuits.
Pressure point
The letter is political pressure, not a new BIS rule. The material issue is whether existing control language is enforced consistently enough to stop diversion through third-country design, fabrication or packaging paths.
What to watch
Whether BIS issues guidance, a rescission rule or enforcement action; whether foundries change attestation requirements; and whether chip companies disclose compliance frictions in China-linked demand.
