“Does anyone know what specific products from China will be hit with this increase?”
Cellphones ($45 billion) and laptops ($39 billion) are the big billpayers; and also PC monitors, networking gear, toys, gaming consoles, meat, fish, and other items.
China only imports about $100 billion in US products, and has already raised tariffs on basically all of it already, in the earlier rounds. Some of those US imports are components that go into Chinese exports, so they would be shooting themselves in the foot by raising tariffs on them. They are basically out of ammo to return fire in kind.
Meat would be mostly pork, and the door should be slammed shut there anyway. Quarantine. (The “pig plague” can be carried by pork products, so, if uncooked or poorly cooked scraps are discarded and fed to hogs, the disease is spread.)
Soybean / feed farmers are going to take a hit regardless, if 200 million Chinese hogs die from disease, in short order, and more in other parts of Asia / the world.
If PC monitors are on that list, I’d guess TV’s might be, too? Some are dual purpose, anyway.
