Mustard Flour, Meal & Prepared Mustard

Mustard is not currently listed as one of the nine major food allergens under US FALCPA, unlike in the EU and Canada where it is a mandatory declared allergen. However, importers supplying mustard flour to food manufacturers who export to those markets must ensure allergen labeling meets destination-country requirements. Domestically, voluntary allergen disclosure is common, and buyers should clarify labeling expectations with their customers before import.

Mustard flour and meal (2103302000) are ground from mustard seed with minimal further processing — no vinegar, salt, or other condiment ingredients added. Prepared mustard (2103304000) is a finished condiment that has been mixed with liquid (typically vinegar or water), salt, and other seasonings. If a product is partially processed — for example, defatted mustard powder with added salt — importers should seek a binding ruling to confirm the correct subheading.
