The ISPM NO. 15 is the standard that governs over the treatment and de-infestation of imported and exported material for ridding these materials form pests. This includes the treating of wood, especially of raw wood, whether it is the main trade material or the packaging. An exception to this is wood that has been processed and rid of pests like plywood.
