Export Control Terms Every Chip Investor Confuses: EAR, Entity List, FDPR
Semiconductor headlines run on a small vocabulary that most readers use interchangeably and almost nobody uses correctly. The difference between a company being added to the Entity List and a company being sanctioned is the difference between a licensing requirement and an asset freeze. The difference between the de minimis rule and the Foreign Direct Product Rule is the difference between a control that stops at the US border and one that reaches into a Dutch or Taiwanese factory. Both mistakes get priced into stocks.
This is a working glossary of the terms that actually move numbers, with the confusions they cause.
EAR
The Export Administration Regulations, administered by the Bureau of Industry and Security within the Department of Commerce. The EAR governs dual-use items: things with both commercial and military application, which is most of the semiconductor supply chain.
The common error is conflating the EAR with ITAR, the International Traffic in Arms Regulations. ITAR is administered by the State Department and covers defence articles. Chip equipment, GPUs and EDA software sit under the EAR. Missiles sit under ITAR. Different agencies, different lists, different penalties.
An item is “subject to the EAR” if it is US-origin, physically located in the US, or foreign-made but captured by one of the extraterritorial mechanisms below. That last category is where the interesting cases live.
ECCN and the Commerce Control List
Every controlled item has an Export Control Classification Number identifying where it sits on the Commerce Control List. For advanced computing the numbers to know are 3A090 and 4A090, which cover high-performance integrated circuits and the computers containing them. Items that are subject to the EAR but not listed anywhere on the CCL are designated EAR99, which is the low-control default.
When a rule is described as covering “chips above a certain performance threshold,” the threshold is written into the ECCN parameters. Rule changes often work by adjusting those parameters rather than by naming companies.
Entity List
A BIS list of foreign parties for whom a license is required to export, reexport or transfer items subject to the EAR. It has grown from roughly two hundred entries at its creation in the 1990s to well over three thousand, heavily weighted toward Chinese firms in telecoms, AI, quantum and semiconductors.
Two persistent misreadings. First, an Entity listing is not a sanction. It does not freeze assets, does not prohibit US persons from dealing with the party generally, and does not stop the company selling its own products. It restricts what can be exported to that party. Second, a listing is not automatically a ban. Each entry carries a license review policy, and that policy is where the economics sit.
Presumption of denial versus case-by-case
The review policy attached to a listing or a control determines whether licenses actually get issued. Presumption of denial means applications are refused absent exceptional argument. Case-by-case means the application is genuinely assessed.
The distinction has been the single most consequential variable in AI chip trade. The January 2026 shift moving Nvidia H200 and AMD MI325X exports to China from presumption of denial to case-by-case review, subject to conditions including a tariff, a volume cap and third-party performance testing, changed nothing about the ECCN and nothing about the Entity List. It changed three words in a review policy, and it repriced the addressable market.
MEU List, SDN List, Unverified List, Denied Persons List
Four separate lists that get collapsed into “blacklist” in reporting.
The Military End User list covers parties subject to restrictions for military end use in specified countries, and it is illustrative rather than exhaustive. The Specially Designated Nationals list is OFAC’s, at Treasury, and it is a true sanctions list: asset freeze, comprehensive prohibition on dealings by US persons. The Unverified List covers parties BIS could not verify through an end-use check, which is an administrative flag rather than a finding of wrongdoing. The Denied Persons List covers parties who have lost export privileges through enforcement action.
Being on the Unverified List and being on the SDN List are not remotely the same event, and headlines routinely treat them as one.
De minimis rule
The classical extraterritorial hook. A foreign-made item becomes subject to the EAR if it contains more than a threshold percentage of controlled US-origin content by value. The threshold is commonly twenty-five percent, lower for certain destinations.
De minimis is a content test. It asks what is inside the product.
FDPR
The Foreign Direct Product Rule is the mechanism most people mean when they say “the US can block that.” It captures foreign-made items that are the direct product of specified US-origin technology or software, or that are produced by a plant whose major equipment is itself a direct product of US technology or software.
FDPR is a provenance test. It asks what made the product, not what is in it. A chip designed entirely outside the US, fabricated entirely outside the US, from a fab full of American-origin tooling, can still be subject to the EAR. That is why Taiwanese foundries and Dutch equipment makers comply with US rules that on their face govern American exports.
Recent expansions have applied FDPR logic beyond hardware, including to model weights trained using controlled US technology. Anyone modelling the reach of a control needs to ask whether it runs on de minimis or on FDPR, because the answers differ by orders of magnitude in coverage.
The Affiliates Rule, or 50 percent rule
Historically BIS applied a legally distinct standard: only the named entity was restricted, and a wholly owned subsidiary trading under another name was not. The Affiliates Rule, published September 2025, closed that by extending restrictions automatically to any entity fifty percent or more owned, directly or indirectly, individually or in aggregate, by listed parties. This mirrors the long-standing OFAC fifty percent rule.
It was then suspended for one year effective November 2025, as part of a broader understanding involving Chinese rare earth export measures, with reintroduction scheduled for November 2026 absent further extension. That date is a live calendar item for anyone holding exposure to companies with Chinese subsidiary customers, and the suspension applies globally rather than only to Chinese entities.
Validated End User
A program allowing pre-approved end users to receive controlled items without individual licenses. VEU authorisations for Korean memory makers operating fabs in China were replaced with annual licenses, which converts a standing authorisation into a yearly renewal decision. The practical effect is not a shutdown. It is the introduction of an annual political variable into capital equipment planning for facilities producing a meaningful share of global DRAM and NAND.
Deemed export
Releasing controlled technology to a foreign national inside the United States counts as an export to that person’s country. This is why engineering teams have nationality-based access controls on design files, and why staffing decisions at US fabs and design houses carry export compliance weight.
Reading a control announcement
Four questions extract most of the signal. Which list or rule changed, and which agency owns it. Does it operate on content or on provenance. What is the license review policy, not just the license requirement. And what is the effective date, including any suspension that expires on a known calendar day.
A headline that says a company was “blacklisted” answers none of these.
