I'm less familiar with the current regulations and restrictions in terms of cross-border shipments, for example, of logs. Legal requirements that mandate the removal of the bark, for example, would certainly be an effective way —or hopefully an effective way—to ensure that stuff gets processed before it reaches the border; before it's even shipped. When it is at the border, try to step up those inspections to verify that products being brought in have been properly treated.
