Hello! Hoping someone may be able to provide guidance.
We currently fill by weight and need to declare our net contents by volume (fl oz / ml). However, each production run will have varying density by +/- 0.05 g/cm^3. We sell the product frozen and instruct the consumers to use it melted.
Does anyone have experience with something this? Is it common to adjust the fill weight for every production run? Or, should we use the max density (equating to the lowest weight) and be overfilling based on the declared contents?
Thanks in advance!
