CATL offers US automakers a pickup battery they would build under license

Tariffs attach to goods and localization rules attach to plants. A license is neither, and the factory that uses one sits on US soil, so CATL's offer to let American companies manufacture its design locally routes around both barriers ^[5]. The designation is the harder term: the Defense Department last year put CATL on its list of companies suspected of ties to the Chinese military ^[4], and the report does not say whether royalties paid to a designated firm would be allowed.

The pressure to try shows up in the production data. Chinese lithium-ion output topped 1,240 GWh in the first half, up 44% from a year earlier, according to the Ministry of Industry and Information Technology ^[12], which implies about 861 GWh in the same half of last year ^[20]. Hold that pace and the year lands near 2,480 GWh, 41% above the 1,755 GWh China produced across all of last year ^[18]. More than 100 plants cleared approval procedures through July with combined capacity of 2,600 GWh a year, according to the China Industrial Association of Power Sources ^[14]. Newly approved capacity by itself is 845 GWh more than last year's entire national output ^[19]. Cathode, anode, separator and electrolyte production each rose more than 50% ^[13].

Trump recently said it would be "OK" for China to build auto plants in the United States as long as they employ American workers ^[9]. Beijing's side of the trade is volume: overcapacity remains unresolved even as global battery demand surges ^[17].

Open door, and CATL earns a royalty on US-built packs without shipping a cell across a customs line. Closed door, and the security rules that stopped the cells reach the license too, leaving a pack engineered for one vehicle format in one country with nobody to sell it to. The third case is the one the demand numbers support, because the US electric vehicle market is retreating sharply after the expiration of tax credits and the administration's rollback of vehicle emissions rules ^[11]. The thesis that a summit reopens this market fails on a single ruling that royalties from a designated company are themselves a security matter.

I'd expect the storage business to pay first. Ford has expanded its CATL partnership on energy storage ^[6], and Beijing has suspended new approvals for energy storage cell plants since May, after a full survey of capacity and utilization rates ^[15]. That freeze points to storage as the segment carrying the domestic overhang. Chinese forecasters have their own share of the global EV battery market falling from 70.4% last year to between 60% and 68% by 2030 ^[16], a loss of as much as 10.4 points ^[21].
