Black Mustard Flour
Black mustard flour is a fine powder produced by grinding black mustard seeds (Brassica nigra) without any further preparation or addition of other ingredients. It is used as a spice or base for making prepared mustard, and its sharp, pungent heat makes it popular in spice blends and pickling. Because it is not mixed, cooked, or otherwise prepared, it falls squarely under tariff item 2103.30.10 as mustard flour.
