It might not be specifically where the parts are made, it IS important to which SPECS they are built to, which includes the materials used. It all depends upon just how much the re-seller wants to sell them at and at what profit level, even if the parts were Made in the USA. Before there were Chinese parts (in the 1960s), there were parts made here that were better than others, as I recall. "Name brands" to trust and others which were not as good.
The vast majority of former (1950s-1960s) USA Name Brands are now a part of probably TWO conglomerates, by observation. Yet there are some Canadian companies whose websites look interesting with some lesser prices, too. As are others are "North American", too. Some of the Asian brands look really nice, too, as they are OEM over there.
Over here, I determined that there were "OEM Level" parts and "used car lot level" parts. The former can include companies as Wix, Fram, Moog, ACDelco, Motorcraft, and similar. The latter are not really bad parts, but will not always be up to the complete standards of the OEM Level group, by observation, but can give good service under many conditions. Nor is everything in the latter group automatically "junk", either.
As to what many of the auto supply chains and smaller auto supplies feeder chains might sell, if it was really bad, they wouldn't be in business very long. Nobody wants a history of warranty returns to deal with. But it's that non-returning customer that costs them, which they do not know about.
By the same token, just because some big-box source might sell some brand of off-shore part does not automatically mean that the off-shore part is a good one, by observation. Just that it might fill a niche in their line-up at a particular price point where they can make money on it. "Greedy profits"? Not necessarily. What might you do if YOU were in that situation?
There are some off-shore OEM Level brands which I do not hesitate to purchase and use, as I have for a long time. Just better for my needs than a USA brand of similar products. But others that I do not desire to even try and waste my money on. FWIW
The KEY is what I term "OEM Level" parts, no matter what, though. With time, though, I have learned which of the non-OEM Level parts which are good, too. Just as I have also learned that spending for higher-than-OEM Level parts is not always a good upgrade to do, at least for me.
In so many cases, the OEM Level items have already been "fire-tested" for 100K mile durability, or as much durability as the OEMs were willing to pay for to get the car to the end of the assembly line and past any applicable warranties. Which opens the door for others to make something better, if desired, at competitive price points. Even to re-sell quality USA-made NOS parts, as
@mobileparts does.
No easy answers, anymore . . .
