Topic tags/keywords: baltic birch counterfeit

How does one identify fake Baltic Birch? There is a Craigslist add for 4×8 sheets.
Does Baltic Birch only come in 5ft widths?
How many layers make up Baltic Birch.

They call it Marine Grade Real Russian Birch

Here is a photo from the ad

Edit: The author of the Craigslist ad copied the picture above from Toledo Plywood, so I have my suspicions.

BB typically has more plys than birch and the plys will be from BB,too. the plys in birch are poplar and other woods.
BB is also stiffer than birch.

BB can be had in 4 by 8, 5 by 5, 5 by 8, and 5 by 10 sizes.
i dont think theres a standard ply count for it but i could be wrong. even then, different thicknesses will= different number of plies.

My nominally 1/2” BB has 9 plys. The nominal 3 /4” has 11. Not saying it doesn’t exist but, I’ve never seen true BB in those thicknesses with less than those counts.
My supplier only handles the 5’X5’ size. Finding it in 4X8 would be nicer to haul.

I can find either 5’ X 5’ or 4’ X 8’ Baltic birch plywood locally. I’d say that the real distinguishing feature is that the face sheets aren’t thin veneer, but the same thickness as the rest of the plies, and all the plies are indeed birch. I’ve not heard of “marine grade”. That would imply that it has an exterior grade glue, and I’ve never seen that with Baltic Birch. I’m willing to be educated on that, though.

Locally we have WoodCraft, and Rockler stores, both of which carry the 5×5 only. A few of the local Wood sources also carry 5×5 s Menards where I source mine has 4×8 s 3/4 for 66 bux a sheet.

Every 4×8 sheet, and most of the 5×5 also have a Cryllic stamp on one corner. I am assuming that it s on just some of the 5×5 s because I have heard they cut 5×10 sheets in half for the 5×5 s.

It comes in larger sizes as well. I once saw 20×40 sheets coming in on a container ship. I was in Baston Taxxachucets with a friend, and he was delivering a tool and die job that was going to Germany. I saw them, and couldn t realize it was plywood. Freaked me out when I heard it was. Frieght guy? Stevedore said they saw it all the time. Made my back hurt thinking of moving a sheet.

The importer of much of it.

Be aware of importers claiming to carry BB ply, and Chinese ply in the same mouthful. Chinese is muti-ply, and often passed as BB ply. BB ply ONLY comes from Finland, and Russia in the Baltic Sea area. [email protected]@K for the Cryllic stamp.

Sheet sizing, and plies per found here.

Grades of BB ply, you want B/BB You’ll know when you see it, usually it is clear both sides. Note they say “allows” up to 3 to 6 patches on the BB back side. Usually zero. I find the 5×5’s have patches more than the 4×8’s

@therealSteveN – I forgot about that stamp. It should be on the sheets as well. Good point.

I usually see it on the edges. Cyrillic characters are a good indication of origin.

I have been told this, and from the source it’s probably correct. There used to be side stamped in Cryllic if it came from Finland, and face stamped if it was from Russia. (&() Chinese (&(()3 started to use some gibberish printed on the edges of the crap they sell, trying to deceive buyers. The Fins have started using the stamp the Russians use. So if it’s new plywood I would be cautious of the side stamped stuff now.

Old Finnish stamp.

The Chinese was placed similarly, but used English letter fonts, and it didn’t make sense. I have heard those were placed in Chiner, and I have heard they were placed here by Home Cheapo????? Would be like
