Most molasses labels won’t have a vegan symbol on the packaging, so it will be safest to either contact the producer and ask if they use sugar processed with bone char, or just buy organic molasses. Then you don't need to worry because organic sugar isn't ever processed with bone char. I always use Wholesome Sweeteners molasses which is certified organic and also labelled vegan friendly. It's easily found in most big grocery stores across Canada and the US.
