wierd grading on Columbia Birch.. Made in USA says ON-GRADE

I can't find anything about ON-GRADE anywhere. I went to Columbia's site could not find anything.
Don't know what it means. see:

Anyone have an idea, got it from HD a few months ago for 51 cents before they stopped doing 51 cents..
The 51 cents were for the remnants of what someone already paid for. ie they bought a full sheet but only needed a portion of it and had it cut.. the rest would go to .51 or 1.02.. no more. Now HD wants 70% of the retail value.

Seems like a reasonable guess from the letters but looking at the stamp on the picture doesn't look like the chance of anything being missing is high since it's so clear over the entire edge so I doubt that's the answer.
Did you try the "contact us" link to ask Columbia directly? Since they have so many specialty products it's likely got a meaning specific to them would be my guess.

No I didn't. Just figured a search on their site would explain it, and it didn't. I guess I could go that route.

I didn't see it at a top level, either, but then again I didn't try to read the detail product data sheet on every product category, either... :)

Helps to understand how lumber is graded for specific use.
When it comes to a specific _use_ for interior, furniture, shop, etc., both hardwoods and softwoods are graded based on "appearance".
Hardwoods are basically "appearance" graded (board size and clear surface area) as a rule; softwoods are generally either one of two categories "construction" grade (strength), or "appearance" grade (finish and select), depending upon use.
With regard to the original question, you will find the phrase "on-grade" used mostly by global suppliers. I don't know it as a fact, but, from lack of any other guidance, I have presumed the phrase, in regard to the product designated as such, was to indicate it was in compliance with said "appearance based" grading standards??
Again, I could be wrong in that regard ...

Seems a plausible supposition; I don't recall having ever seen it before the posted picture. Then again, we don't have any of the big box stores around here...
Interestingly, like OP I did some searching and found no reference whatever to it in any of the ply association trade group sites or grading references, nor did a search at the Forest Products Lab site return any seemingly relevant hits. I didn't spend a lot of time, but generally stuff will show up pretty quickly...
But, that's as a good a guess as we gots at the moment until/unless OP does contact Columbia and gets an answer and then lets us know what they say...
I'd also guess it's that or something very similar.

I've always thought it was relevant to "appearance" ... IOW, the "appearance" of the plywood is "on grade" if it coincides with the standard plywood grading system of the country or area with regard to the "appearance" of lumber grade it is produced from.
But, I could be wrong ...
