The foregoing list reflects FDA's current best judgment as to those nuts that are "tree nuts" within the meaning of section 201(qq). In order to be comprehensive, this list employs broad scientific categories that may include a species that currently has no food use. The fact that a species falls within a scientific category on this list does not mean that the species is appropriate for food use. FDA further advises that, as with any guidance, the list may be revised consistent with the process for revising guidance documents in our regulation on good guidance practices in 21 CFR 10.115.
