Randy, the post office has updated the unauthorized list and wood has been taken off, but customs still has a local wood restriction on it's list. The term local is used of any untreated wood and they just suggest not to try and take any out since if in doubt they will confiscate it.
Basically it will be up to whoever inspects your package at the post office as to if it can be shipped or not. There was so many issue with frames, plaques, and such that it is just easier for them to have to inspect packages with wood that looks untreated or not manufactored.
You may have a good chance of getting it shipped out. Good luck and hope you can put the wood to good use.
