Where to buy heat treated Plywood or OSB and lumber?
 
In the South East Wisconsin area, in and around Waukesha and Milwaukee, where can I get heat treated Plywood or OSB and heat treated lumber?

The products must have the HT tag/stamp on them.

At Menards, they say their CDX plywood is heat treated but it doesn't have the tag/stamp on it. They have lumber 2x4 that says HT only on the cross section. I need the lumber to say HT on the sides.

This is for making an export crate to comply with export regulations, which is why I need a stamp or printed on the products.

Heat treated as in kiln dried?, or heat treated as in fire retardant lumber?

I think it is klin dried.

Here is the explanation.

The international export standard, ISPM 15, requires that all wood packaging material be heat-treated at a core temperature of 56 degrees Celsius for a minimum of 30 minutes.
Here is a tag with HT

It's to kill insects.

For export/import purposes, the HT designation isn't the same as kiln-drying.

Spud, try an actual lumberyard. Not a box store, but somewhere that sells nothing but lumber. The HT grade stamp availability may be hit and miss though, you'll just need to call around.
