USDA honey grades are voluntary and measure clarity, flavour, aroma and freedom from defects rather than purity or authenticity.
The United States Standards for Grades of Extracted Honey are issued by the USDA Agricultural Marketing Service as voluntary standards used on request, and the grade factors are soluble solids, defects, flavour and aroma, and clarity.
What this does not claim: This is not a claim that graded honey is unregulated. Federal misbranding and adulteration law applies regardless of grade, and several states have their own honey standards. Nor is it a claim about the current content of any FDA guidance, which is issued and revised separately from the grading standards.
