The FDA Standards of Identity, which we follow, lists, “Sugar Free" as less than 0.5 g sugars per RACC (Reference Amount Customarily Consumed) and per labeled serving size . It also contains no ingredient that is a sugar or generally understood to contain sugars. Coco Polo’s 70% Dark was developed originally in 1996 as fully “Sugar Free”.
"No Added Sugars" and "Without Added Sugars" are descriptions allowed if no sugar or sugar containing ingredient is added during processing. It is also used if the naturally occurring sugars present, such as from nuts, exceeds the 0.5 g sugar rule per serving size
Zero Added Sugar is another description similar to No Added Sugars.
