What Chinese Companies Should Ask Their Korean Suppliers About US Export Licenses

Export Controls & Korea–China

Context → BIS Applied Materials settlement, 11 February 2026 — the case that made these questions necessary

This piece is written for the Chinese side of the Korea–China supply chain — the procurement and legal teams at Chinese robotics, equipment, and chip companies that buy components and tools from Korean suppliers. The message is direct: “Made in Korea” does not, by itself, tell you whether a U.S. export license is required. The Applied Materials settlement proved why, and it gives you a concrete reason to ask your Korean suppliers a short list of questions before you sign.

Why Korean origin is not the answer

U.S. export jurisdiction does not turn on where a product is finished. It turns on whether the item is “subject to the EAR” — which includes U.S.-origin items wherever they are located, and certain foreign-made items that contain enough U.S.-origin controlled content or are produced with U.S. technology or tools.

In the AMAT case, tools were partially built in the U.S., finished in Korea, and shipped to SMIC in China. BIS held that the Korean finishing step did not remove U.S. jurisdiction: U.S.-origin items are not made “foreign” by overseas assembly that uses “little or no foreign-origin parts” (Order, p. 12). SMIC received equipment it presumably believed was properly routed; it ended up at the center of a $252.5 million enforcement action. The lesson for a Chinese buyer is that your supplier’s Korean address does not resolve the question — the U.S.-origin content path does.

The three things that determine whether a license applies

  1. The component’s classification. Is it EAR99 (the lightly controlled catch-all) or does it carry a specific ECCN (e.g., 3B991 for certain semiconductor-manufacturing equipment)? EAR99 items face minimal controls in most cases; an ECCN-classified item may require a license for China specifically. But note: even EAR99 items can require a license if a party has received an “is-informed” letter — so classification alone is not the whole answer.
  2. Your regulatory status. Are you, or any affiliate in the transaction, on the Entity List, or otherwise a restricted party (military end-user, for example)? If so, the license requirement can expand to all U.S.-regulated items, regardless of how low-tier they are. SMIC’s Entity List designation moved its license universe from specific items to everything in under three months (Order, p. 4).
  3. The U.S.-origin and U.S.-technology path. Was U.S.-origin content shipped into the Korean production chain? Were U.S.-origin tools or technology used to produce the item (the Foreign Direct Product Rule)? Either can pull the Korean-made output under U.S. jurisdiction even if the final assembly is entirely Korean.

There is a genuine safe harbor worth knowing: BIS excluded the Singapore-origin enclosure and factory interface in the AMAT case because they were truly foreign-made and cleared the de minimis and FDPR tests (Order, p. 7). Foreign-made sub-assemblies that clear those tests are not the exposure. U.S.-origin content that gets integrated is.

What to request from a Korean supplier

Before signing a supply contract, ask the Korean supplier to provide, in writing:

  • Export classification: the ECCN or a documented EAR99 determination for each component or tool you are buying.
  • License basis: for any ECCN-classified item destined for China (or for your specific entity), the license or license-exception citation the supplier is relying on.
  • U.S.-origin content path: whether U.S.-origin parts or subsystems are integrated into the item, and an estimate of U.S.-origin controlled content.
  • FDPR analysis: whether U.S.-origin technology or tooling was used to produce the item, and the supplier’s conclusion on whether the foreign-direct-product rules apply.
  • Restricted-party screening: confirmation that the supplier has screened your entity (and end-use) against the U.S. restricted-party lists, and the result.

A supplier that can answer these cleanly is a supplier who has done the work. A supplier that treats the questions as strange is a risk you are inheriting.

Why this is now reasonable to ask

Two years ago, asking a Korean supplier for an FDPR analysis might have seemed aggressive. After AMAT, it is ordinary diligence. The case put on the public record exactly how U.S. jurisdiction can follow U.S.-origin content through a Korean factory to a Chinese buyer — and how expensive it is when the analysis is wrong. A Chinese company conducting due diligence on a Korean acquisition, or a Chinese law firm advising on Korean supply-chain risk, now has both the vocabulary and the precedent to make these requests standard.

The short version: do not buy the assumption that Korean origin equals no U.S. exposure. Buy the documentation that actually answers the question.
