Looks like in the EU "sugar free" is limited at 0.5g sugar per 100g or ml of product: https://ec.europa.eu/food/safety/labelling-and-nutrition/nutrition-and-health-claims/nutrition-claims_en https://ec.europa.eu/food/safety/labelling-and-nutrition/nut... I checked one and it contains 0.1g of sugar per 100g, but it's not added sugar, it's contained in the other ingredients. I don't know if it's possible to make it with absolutely 0g of sugar. But there is no separate ingredient "sugar" there.
