A U.S. Secretary Warned Apple Off Chinese Memory; No Rule Bans It
The U.S. Commerce Secretary told The Wall Street Journal plainly that the administration opposes Apple buying memory from Chinese manufacturers. But one of the two suppliers is not even blacklisted, and the blacklist does not forbid that purchase anyway.
A Ribbon in Houston, a Headline the Next Day
On August 13, a ribbon was cut at Apple's new manufacturing facility in Houston. Tim Cook held one end of it; U.S. Commerce Secretary Howard Lutnick held the other. The following day, The Wall Street Journal published what Lutnick said after the ceremony. Asked about Apple buying memory chips from Chinese manufacturers, he said: "The Trump administration is not in favor of that." There were other solutions to the memory problem, he added, but the solution could not be "great American companies using Chinese memory."
Asked whether he had told Apple this directly, he answered in one word: "Plainly."
Headlines read it as "the U.S. blocks Apple." It did not. Lutnick announced no ban, issued no rule, published no draft in the Federal Register. He stated a preference. And that is precisely the subject of this piece: as of today, no instrument exists to make that preference binding.

Binding U.S. rules that stop Apple today
The two Chinese companies on stage occupy different legal positions. Yangtze Memory (YMTC) has been on the Commerce Department's Entity List since December 16, 2022. ChangXin Memory (CXMT) is not on it. Both appear on the Pentagon's list of Chinese military companies, but that list does not prohibit commercial purchases; it mainly governs Defense Department procurement and shapes investor perception.
What a Blacklist Forbids, and What It Does Not
The common misunderstanding here concerns what the Entity List actually does. It is an export control instrument. It requires a license before a U.S. company gives goods, software, or technology to a listed firm. It does not govern the reverse: a U.S. company buying a finished part that the listed firm manufactured in China.
The distinction is not academic. Export controls lawyer Kevin Wolf summarized it for The Wall Street Journal in a single sentence: Apple can buy off-the-shelf CXMT components and haggle over price, but it cannot commission chips designed to its own requirements.
Why the Trigger Never Gets Pulled
For the rule to engage, Apple has to do something specific: ask for customization. Order a custom chip and you must share technical specifications; sharing specifications is a technology transfer; a technology transfer requires a license; a license application lands on the Commerce Department's desk, and the department can refuse it. Every link depends on the one before it.
The Chain That Triggers the Rule
- 01Customization requestApple writes its own specification
- 02Technical disclosureThe specification crosses to the other side
- 03Technology transferIt falls under the EAR
- 04License applicationCommerce can refuse
Break the first link and the rest never forms. Buying a standard, off-the-shelf memory chip requires giving no one a specification — the part is already built to catalog. No transfer means no license, and no license means no moment ever arrives at which the department could intervene.
In Houston, Apple COO Sabih Khan declined to confirm that Chinese chips were being tested, but he did offer one line: with memory chips, "there isn't a lot of customization." That is not an idly chosen technical detail. It is a statement that Apple has positioned itself outside the regulatory trigger.
The Memory Bill: One Line Item Accounts for All of It
So why is Apple knocking on such a risky door? The answer is in memory prices. According to TrendForce's August 10 estimate, the bill of materials for the 256GB iPhone 18 Pro rose roughly 38% year over year, and memory's share of that bill climbed to about 34% in the third quarter. A year earlier that share was roughly 10%.
Put those two figures side by side and the result follows.
The arithmetic is a rough approximation — the percentages come from different reporting periods. But the order of magnitude holds, and it explains Apple's behavior. The company raised the MacBook Air M5 by $200 in June and lifted prices across Macs, iPads and home devices; even so, lead times on 24GB and 32GB configurations have stretched to five weeks. TrendForce expects Apple to give up part of its gross margin on the iPhone 18 line to soften the increase.

Not Cheapness — Availability
This is the most widely mis-told part of the story. Most headlines said Apple turned to China "to cut costs." Yet according to reporting on the talks, CXMT's prices are level with those of Samsung, SK hynix and Micron, and in some cases above them.
Paying the same price to a supplier that carries blacklist risk explains only one thing: allocation. On its December earnings call, Micron said it could meet only 55–60% of its core customers' demand. If price does not solve the problem and queuing does not solve it either, what remains is the door that is not on the list.
Global DRAM Market Share, Q2
- Samsung%39
- SK hynix%26
- Micron%25
- CXMT%7
- Others%3
CXMT's 7% may look small, but its revenue rose 716% year over year in the same period, making it the fastest-growing DRAM supplier in the world. On the NAND side the share is higher still: Counterpoint data published August 12 put YMTC third globally in bit shipments with a 14% share, passing Micron and Kioxia for the first time. That headline ran exactly one day before Lutnick spoke.
Washington's Three Separate Doors
There is no single authority pressuring Apple. Three voices are coming from three places, and none of them holds the same instrument.
| Who | What they want | The instrument they hold |
|---|---|---|
| Senators (July 29 letter) | A commitment not to use CXMT or YMTC memory in any device | None — public pressure and an August 21 reply date |
| House Select Committee on China | CXMT added to the Entity List, further limits on YMTC | None — a letter to the Commerce Department |
| Commerce Department | Apple to walk away | Real but indirect: the authority to add CXMT to the list |
| Micron | The plan rejected | Lobbying; met with Lutnick in July |
The senators' letter already rejects Apple's likely defense that the parts would go only into devices sold in China: once a component clears qualification for Apple production, they write, extending it worldwide is a single procurement decision away. As of August 15, Apple has not replied to the letter.

What the Market Actually Priced
Memory stocks rose on Friday: SanDisk gained 7%, Western Digital 4%, Micron 3%; in Korea, SK hynix added 3.26% and Samsung 2.43%, while the KOSPI closed up 2.41% to end the week 11.5% higher. Attributing that move to Lutnick would be wrong — the day's real catalysts were SanDisk's investor day and a soft U.S. inflation print. No source draws the causal link.
The real information is in Apple itself. AAPL closed Friday almost flat, up 0.22%. Yet on August 9, when the news broke that Apple was testing CXMT parts, the stock fell 1.54%. The market is pricing a supply risk; it is not pricing a ban. That is the most concrete evidence for the argument that no binding rule exists.
The chart below shows how the memory side has traded over the past three months. It is context only, not evidence for the argument above.
What Is Left
Three separate things are true at once. The Commerce Secretary does not want Apple buying Chinese memory. No binding rule stops Apple from doing so. And the department has the power to create one — adding CXMT to the list is a matter of a signature.
That is why Apple's June request for assurance that CXMT would not be listed matters. The company knows the risk exists and understands it as political rather than legal. Risk of that kind cannot be closed with a contract, because the counterparty does not sign contracts.
