Quite apart from the dimensions, I Googled "Chinese plywood" looking for more info. I don't know if they are true but there are a LOT of stories out there about inferior quality, and also possible toxicity of the glue. With so many from people claiming to be woodworkers, I think I'd pay extra for domestic.

Keep in mind that I used a $10 tape measure with an unassigned uncertainty value to measure it. And I took one measurement of one panel. This is the summer season and the plywood can expand a bit due to moisture and temperature. The temperature in my house, in which it has now been sitting for ~12 h, is ~25 °C with a relative humidity of 54 %. Jim John M.
