Bark Restriction Terminology
The official definition of debarked wood:
Irrespective of the type of treatment applied, wood packaging material must be made of debarked wood. For this standard, any number of visually separate and clearly distinct small pieces of bark may remain if they are: – less than 3 cm in width (regardless of the length) or – greater than 3 cm in width, with the total surface area of an individual piece of bark less than 50 square cm.” [per the Revised ISPM 15 Annex 1]
The official definition of bark free wood:
This definition was created by Australia, however, effective July 1, 2010, Australia no longer requires this level of bark restriction. Instead, Australia has adopted the international standard set forth by the 2009 revision of ISMP 15 Annex 1
“…ZERO tolerance for bark on timber packaging and dunnage. Bark is the external natural growth layer covering trees and branches…bark around knots, bark pockets between rings of annual growth, and inclusions in the vascular cambium are difficult to remove. However these have the potential to harbor quarantine risk materials such as fungal spores, fungal decays and insects.” [per Australia’s AQIS Website]
