Everything Is Tradable Except the Chips

In October 2025, Donald Trump and Xi Jinping sat down and traded almost everything. Tariffs came down from 57% to 47%. Rare-earth exports resumed. Port fees were suspended. ^[1] The one category neither side would put on the table was advanced semiconductors — Nvidia's Blackwell chips stayed restricted even as everything else moved. The chips were carved out, not traded. Trump was explicit about the role he wanted to play.

I said (to Xi) that's really between you and Nvidia, but we're sort of the arbitrator or the referee. — Donald Trump

That split — broad tariffs negotiable, specific components not — is the real structure of the trade war. The tariffs are the loud part, the part that gets cut in summit deals and swapped out when courts strike it down. The decoupling is the quiet part, and it happens one component at a time. The Apple memory-chip case shows the mechanism at its sharpest. Squeezed by the AI-driven memory shortage, Apple petitioned in June to buy chips from China's CXMT and YMTC — first for products sold outside the US, then for everything. The Chinese suppliers had the spare capacity Apple needed. ^[2][3] Micron's chief executive, Sanjay Mehrotra, personally lobbied Commerce Secretary Howard Lutnick and Treasury Secretary Scott Bessent to block the deal, warning that state-subsidized Chinese firms would gut the domestic chip industry. ^[3] Lutnick made the administration's position plain.

There have to be other solutions to the memory issue, but it’s not great American companies using Chinese memory. — Howard Lutnick

The government didn't just say no. It steered Apple toward an alternative it partly owns: Intel, in which the US government holds a 10% equity stake worth over $600 billion. ^[4] And it used Apple's own $600 billion US manufacturing commitment as the lever. ^[5] A domestic supplier against a domestic buyer, a state-backed alternative as the off-ramp, the company's own promises as the pressure point. That is component-level decoupling, applied to a single sourcing decision. The same pattern runs across the board. The GAIN Act, passed in October 2025, requires Nvidia and AMD to fill domestic orders for advanced AI chips before foreign ones. ^[6] In June, the Commerce Department's Bureau of Industry and Security closed the loophole that let Chinese firms get Blackwell chips through overseas subsidiaries in places like Malaysia. ^[7] The defense bill bars the Pentagon from buying batteries from "foreign entities of concern" — mostly China — even as officials concede that every US weapon system contains foreign parts. ^[8] China runs the same play in reverse. It restricts specific rare-earth minerals — cadmium, yttrium, samarium-cobalt magnets — that aerospace and defense can't do without, and 76% of affected US companies are now hunting for non-Chinese suppliers. ^[9] Yet its broad tariff countermeasures stayed negotiable: the October truce cut tariffs and resumed rare-earth exports even as the mineral controls stayed in place. ^[1] The obvious objection is that the tariffs never went away. Trump called them "permanent" in December 2025. ^[10] When the Supreme Court struck down the IEEPA-based universal tariffs, the administration simply replaced them with Section 301 duties covering 99.4% of imports. ^[11][12] But that persistence is the point, not a contradiction. The tariffs are the public instrument — the revenue engine, the headline, the thing that gets renegotiated and re-legalized. The decoupling runs underneath them, and it stays off the table. Two layers, running in parallel. One is loud, tradable, and replaceable across legal regimes. The other is quiet, surgical, and deliberately excluded from every bargain. The trade war's public face is a number that moves in summit deals. Its actual work is a chip model here, a battery component there, a memory supplier steered away from a buyer — pressure applied to individual companies to excise individual parts.
