Thanks I've been looking for that list but not with vigor.
It looks like PRC T&M companies will be in trouble.
If anyone has been on the fence for gear its now or never, most any general purpose T&M instrument even in the MHz like a Rigol 1054z can be used for 'telecommunications' so its open to interpretation. Voltage control can be as mudane as a wall wart as defined below. But it much clearer that this involves at least DMM, signal sources and soldering irons/guns.
NESI or NESOI means 'not elsewhere specified or included' ergo a catch all for the category.

I was reading an article about the new 25% tariffs that Trumps wants to put on 1300+ products/items from China, and luckily there was a link to the document.
Included in the list, apart of industrial equipments, steel/iron/aluminum there is also a lot of electronic testing gear and also components like:
