The Foreign Direct Product rules are a set of provisions in the United States Export Administration Regulations, codified at 15 CFR § 734.9, that bring foreign-made items located outside the United States within the EAR's jurisdiction. An item falls within the rules when it is a "direct product" of specified United States technology or software, when it is produced by a complete plant or major component of a plant that is itself such a direct product, or, for certain specified commodities, when it contains an item produced by such a plant (Source: ecfr.gov).
The doctrine is the principal legal instrument by which United States export controls reach semiconductors fabricated abroad by non-US firms. Because advanced logic fabrication depends on United States design software and equipment, a chip made in Taiwan by a Taiwanese company and sold to a third country can require United States authorization when it is ultimately destined for a controlled destination. The scope and consequences of that reach are treated at Export Controls (AI) and Chip Smuggling and Export-Control Evasion.
Structure
Each FDP rule in § 734.9 pairs a product scope with a destination, end-user, or end-use scope; an item is subject to the EAR only when it satisfies both. The section is organized into lettered paragraphs, each defining one rule — a national-security FDP rule, a 9x515 and 600-series rule, an entity-list rule with several sub-paragraphs including one directed at foreign-produced commodities, an advanced-computing rule, and further rules addressing specified destinations and end uses (Source: ecfr.gov).
The section in its current structure dates to 87 FR 6024 (February 3, 2022) and has been amended more than a dozen times since, including at 87 FR 62195 (October 13, 2022), 88 FR 73488 (October 25, 2023), 89 FR 96810 (December 5, 2024), 90 FR 4557 and 90 FR 5308 (January 2025), and 90 FR 47211 (September 2025).
Application to advanced computing
The Bureau of Industry and Security introduced two FDP rules addressed to advanced computing in the interim final rule of October 7, 2022, "Implementation of Additional Export Controls: Certain Advanced Computing and Semiconductor Manufacturing Items; Supercomputer and Semiconductor End Use; Entity List Modification" (87 FR 62186, published October 13, 2022). The Bureau's stated reason was that many of the advanced computing integrated circuits controlled by that rule are produced outside the United States by manufacturers relying on United States software, technology, or tools, so a control limited to United States-origin items would not reach them (Source: federalregister.gov).
The October 25, 2023 interim final rule (88 FR 73458) adjusted the technical parameters defining a controlled advanced computing integrated circuit and extended the licence requirement to Country Groups D:1, D:4, and D:5 as an anti-circumvention measure.
The December 5, 2024 interim final rule (89 FR 96810) added further FDP rules directed at impairing the capability of specified destinations and entities of concern to produce advanced-node integrated circuits, added controls on certain high-bandwidth memory important for advanced computing, and clarified controls on software keys enabling the use of tools. It was issued the same day as a final rule adding entities to the Entity List and removing firms from the Validated End-User programme.
Enforcement and circumvention
The FDPR is the legal basis for enforcement against transactions in which a controlled item reaches a restricted end user through intermediaries. Following the expansion of FDPR controls on Huawei, TSMC was found in late 2024 to have shipped approximately two million advanced dies fabricated to Huawei specification through intermediaries including Sophgo, in violation of export controls as interpreted by the Bureau; TSMC halted the relationships and disclosed to the agency, and Gregory Allen of CSIS documented the pattern (see Chip Smuggling and Export-Control Evasion).
The AI diffusion rule published in January 2025 controls model weights, including through the foreign direct product rule, but is not being enforced pursuant to a May 2025 Bureau announcement, so licence requirements on AI model weights are not in effect; that reading is set out at The Department of Commerce Restricted Access to Anthropic's Latest Models. What Comes Next? (CSIS, June 2026) and the rule itself at BIS Framework for AI Diffusion — Interim Final Rule (RESCINDED).
Debates and positions
The rule is the most extraterritorial instrument in the export-control toolkit, and commentary divides on whether that reach is sustainable. It creates friction with allied jurisdictions whose firms are subject to United States licence requirements for transactions with no United States nexus other than the tooling used, a tension noted at Chip Smuggling and Export-Control Evasion.
In the strategic literature, the FDPR appears as evidence for the position that the United States can hold a durable compute advantage: on that account, under the rule roughly all advanced semiconductors destined for China require United States permission. The counter-position identified in the same material is that controls can be circumvented — DeepSeek and the Huawei Mate 60 Pro are cited as cases — that algorithmic efficiency may matter more than raw compute, and that leadership disappears if the frontier becomes commoditized. Both readings are set out at Three Theories of Victory (US / EU / China AI Governance).
The mechanics as taught to a policy audience, including the ITAR/EAR distinction and the 3A090 classification for advanced AI chips, are recorded at Inside My AI Law & Policy Class 23: When Silicon Valley's Effective Altruists Meet Washington's Export Controls (Farahany / Hamilton, November 2025).

Open questions
- Whether the model-weights controls in the AI diffusion rule are revived, and on what terms, has not been announced as of August 2026.
- Whether allied jurisdictions adopt equivalent domestic controls in place of accepting United States extraterritorial licence requirements remains unresolved.
