Bark Free Wood Definition, Photos, Tests

A Definition for Bark free wood is provided below:

Bark Free wood packaging material means that there is ZERO TOLERANCE for bark. There is no acceptable level of bark on a board to be considered Bark Free. There are currently no countries requiring this degree of bark restriction.

AUSTRALIA HAS RELAXED ITS POSITION ON BARK FREE WOOD PACKAGING TO MATCH THE INTERNATIONAL ISPM 15 BARK RESTRICTIONS

Bark Free Discussion [EXAMPLE1]

  1. [BOARD 1] This board has bark and vascular cambium, it is considered to be within the limitations of debarked lumber, but NOT bark free. FAIL
  2. [BOARD 2] This board is very similar to #1. It has small non-continuous pieces of bark. None of the bark on this board measured wider than 3cm, but it is NOT bark free. FAIL
  3. [BOARD 3] Two small strips of bark run along each of the top edges of this board. The strips are both less than 3cm wide. Because they less than 3cm wide, they could both run the whole length of the board and still pass as debarked, but the board is NOT bark free. FAIL
  4. [BOARD 4] There is no bark on this board. There is vascular cambium, which does not count as “bark”. This would count as debarked, but there is no clear definition of how Australia treats cambium. Timber Creek policy is to remove even the vascular cambium to avoid potential problems oversees. Therefore this board is NOT bark free. FAIL
  5. [BOARD 5] Similar to #3, this board has a thin strip of bark that counts as debarked, but is NOT bark free. FAIL
  6. [BOARD 6] This board is BARK FREE. There is absolutely no bark or cambium on this board. PASS
