Sugar-free chocolate needs a product and portion check. The Hershey’s Special Dark Zero Sugar reference lists 19g total carbohydrate and 3g fiber per 4 pieces (32 g), with maltitol as its first ingredient. A product-specific net-carb value is not established here.

YOUR PORTION
How much are you having?
Scale the published reference values to your portion.
Per 4 pieces (32 g; Hershey’s Special Dark Zero Sugar; rounded label values). Product label.
These are rounded label values. Scaling them cannot recover small amounts hidden by rounding. Missing nutrients remain unavailable.
How this is calculated
Not calculated: a product-specific maltitol deduction has not been established. Total carbohydrate and fiber are shown separately.. Each published value is multiplied by your portion divided by the reference amount. No extra fiber, sugar alcohol or allulose deductions are applied here.
Grams and milliliters are not interchangeable. Household measures require a food-specific conversion; check your scale or product label.

Net-carb calculation: Not calculated: a product-specific maltitol deduction has not been established. Total carbohydrate and fiber are shown separately.
The manufacturer’s US 3 oz bag reference lists 19 g total carbohydrate, 3 g fiber, 2 g protein, 10 g fat, 0 g total sugars and 130 calories per 4 pieces (32 g). Maltitol is the first ingredient. A generic sugar-alcohol deduction cannot substantiate the former 2.5 g net-carb estimate per 100 g. Values vary across sugar-free chocolate products. The linked affiliate options have different formulations; this panel does not apply to them.

No added sugar does not mean sugar-free: the manufacturer label reports 2 g total sugars per 3 pieces (34 g). This milk-almond bark is a different formulation from the zero-sugar reference above. Check the current label and allergens.
