Product with sugar labeled as "no sugar"

Each pack weighs 15–18 g and contains about 36 Tic Tacs. New packs in Australia and Canada weigh 24 g and contain 50 Tic Tacs, and the Tic Tac "Big Box" weighs 49 g and contains 100 Tic Tacs. The "Big Pack" weighs 29 grams (1 ounce) and contains 60 pieces. The "Jumbo Pack" weighs 98 grams (3.4 ounce) and contains 200 pieces.

Each Tic Tac weighs just under 0.5 g. Since US federal regulations state that if a single serving contains less than 0.5 g of sugars it is allowable to express the amount of sugar in a serving as zero, and since a single serving of Tic Tacs is a single Tic Tac, Tic Tacs are labeled in the US as containing zero sugar.
