Here in the northeast the lumberman's association that issues grade stamps to mills told us that they wouldn't issue a grade stamp to a portable sawmill. So I can't get one.
To overcome this problem when a building inspector wanted grade stamped timbers, we (the customer and I)hired the association's traveling graded to come here to my sawmill yard and inspect and grade stamp all the timbers.
This then satisfied the building inspector for the town where the barn was going to be built.
If you contact the WWPA ask them about hiring a grader who will travel to your site and inspect your timbers.
When he arrives he'll want to look at every timber and every face of every timber so be prepared to lay them out so he can look at everything. He'll also want to know which are posts and which are horizontal timbers as different grade rule apply to these timbers. At least they did when he came here to my yard.
Good luck with your project.
