Label on Wood, what's this mean?

[Patrick Irish]

I think it means heat treated Japan. Any idea of anything else? If chemicals were used or not? Several boards were milled and processed and much do not look the same. Lot of vary in color. Same weight though.

It looks like it was dunnage used for a shipping container. Most countries require that any wood being imported be heat treated to prevent the spread of insects. The heat treatment is not the same as kiln drying as they don't check moisture levels, just temperature reach for the required duration.

The military requires kiln dried wood for their pallets because they have automated warehouse systems and warpage can jam stuff up. But they do not care how wet the pallety is as long as it was kiln dried at some time in it's life.

In Canada ..

The # is the mill number .. or more specifically a stamp number which leads back to the mill .

HT is Heat Treated.. No bugs.. mold .. etc.

And the small logo would be the grading company . PLIB for instance is Pacific Lumber inspection board. I can't read that one but if you google it, I would bet is some lumber grading rule assn.

Most borders won't accept pallets that are only KD .. Kiln Dried wood can still contain living organisms. SPF for instance is commonly dried to 17% .. Heat Treated wood is basically sterile.. Its heated to an extreme temperature for a minimum amount of time.
