It looks like the country of origin is not required if a USDA grade is not printed on the label...
" Under this rule, any honey that has an official U.S. grade mark must include in its label the country of origin in letters at least the same size and in close proximity to the grade mark. For example, if foreign or domestic honey were labeled U.S. Grade A, then it would have to identify its country or countries of origin. Conversely, if the honey is not officially grade labeled, the country of origin labeling is not necessary whether the honey is domestic or foreign."
What part of the Code of Federal Regulations don't you understand?
