Mustard Flour, Meal & Prepared Mustard

France is the dominant US supplier of prepared mustard, consistent with its globally recognized Dijon and specialty mustard industry, while Canada leads in mustard flour and meal given its position as one of the world's largest mustard seed producers. The US schedule separates mustard flour and meal (2103302000) from prepared mustard (2103304000), with a residual combined line (2103300000) also present — making the degree of processing the primary classification criterion. FDA regulates these products as processed food condiments, and prepared mustard formulations containing wine or other alcoholic ingredients may require additional review. Importers should confirm whether the product is a raw milled ingredient or a finished condiment, as the distinction determines both the applicable tariff line and labeling requirements.
