I remember when I bought my brand new VR10000 in 2014 that the solenoids were Chinese and some parts had a Mexico label and some had USA...so basically just a Chevy, dodge or ford type of situation where they have cheap crap made in other countries and assemble it wherever with the minimum required percentage of US made parts to qualify it for the made in USA sticker. At least it's not like Chevy and ford where they have their parts cast and machined in Mexico and their product assembled in Mexico just across The border and finished with enough American part to qualify it. As mentioned by @shocktower they're assembled in Oregon...which isn't much better than China or Mexico because the whole state is high out of their minds anymore.
All of the machined and cast parts are right here, in Oregon and if you work there, you have to pass a piss test, when ever they want. BTW I don't do anything no alcohol or anything to get high, ok I do crack the windows to smell burning diesel fumes
