I just had the windshield replaced in my 2002 Camaro that I'm picky about. Had a body shop that works on $100k+ classics make a recommendation on a glass installer.
Long time independent shop. Owner came out to help his worker. I had indicated to him I was willing to pay for top glass. Didn't want Chinese glass.
He related to me that the top U.S. glass companies have been bought out by Chinese industrialists (or one industrialist, don't remember). There have apparently been culture shocks on both sides. I'm not sure if quality has been impacted, but I have no doubt it will be.
So I think I ended up with U.S. made Chinese glass. That statement about not having a choice may be true sooner than later.
Nowadays the brand names etched into the glass don't really mean much.
PPG is no longer in the business. They were renamed to PGW and I believe are currently owned by LKQ Corp. If you buy any PGW windshields now, they all seem to have a DOT563 mfr code which is XYG based out of China.
Pilkington was bought by Nippon Sheet Glass, which is potentially OK since NSG still makes decent quality glass in their Japanese plants.
Fuyao is the one you're probably talking about where the Chinese billionaire owner opened up a plant in Ohio to produce glass here. Some of their stuff is OK, some of it is meh. I detailed a Honda Civic recently that had an OEM Honda windshield made by Fuyao and it was flawless. The Fuyao windshield on my vehicle has terrible distortion at the edges.
Frankly it seems like Ford and Carlex are the only ones not impacted yet. I've started looking to see which cars in the grocery parking lot have replacement glass and Fords rarely seem to. My previous vehicle, an F150, managed to keep the OEM windshield for 13 years until I sold it. Tons of 'speckling' from road debris but no chips or cracks.
Similarly, a friend of mine has a Nissan Titan which also has Carlex glass and it has been through dozens of hail storms and no cracks or bullseyes.
