First off I have had ok luck with the China "Birch" plywood. But decided when I make my next set of cabinets I would try something a little better. So I go to one of my local "Real" lumber yards and talk to the sales guy. He said he had shop grade Birch plywood for $45 a sheet. I specifically asked if it was the China stuff and he said no. So, I pay for 5 sheets and go out to the yard and pick them up. I started to wonder as it looked just like the Borg stuff but didn't see the tell tale label on it. So, I loaded up the 5 sheets and drove home. Thinking I got some decent ply for shop cabinets for only about 10% more than the Borg's. Was feeling pretty good.
Then I got to my shop and was getting ready to unload the ply. On the side where the lumberyard guy was helping load the ply were these big blue stamps. MADE IN CHINA Not only was it the same CHINA stuff but it ended up costing me $6 a sheet more! I thought it over and decided I would take it back. So, I took it back and was helped by a different salesman. He asked why and I said its the same made in China stuff sold at Lowes / HD. And I said I specifically asked before I bought it if it was mad in CHINA or not. After some talking I ended up switching to some 7 ply fir A/C ply for same price.
The other option was what they list as Birch ply for $72 a sheet. But they could not tell me the source of it. So, I just opted for the FIR.
I have had ok luck with the China stuff. But I am definately not going to pay more for it while still risking that I may get a bad sheet. Their recipt even says no waranty under the product. So they know it may delaminate. And unlike the Borgs will not take it back if it does. I will see how this FIR works out. I really dont want to pay $72 a sheet for garage cabinets.
