Vinegar and Acetic Acid Substitutes for Vinegar

The product classifies under heading 220900, but 'Balsamic Vinegar of Modena' is a protected geographic indication in the EU. While the US does not provide the same level of GI protection, FDA food labeling standards apply, and importers should ensure the product meets FDA's standards of identity for vinegar (minimum 4 grams of acetic acid per 100 mL) and that label claims are truthful and not misleading. CBP may also scrutinize origin claims on GI-designated products.

Both are classified under heading 220900, but they differ in production method and FDA labeling treatment. Traditional vinegar is produced by acetic acid fermentation of alcoholic liquids (wine, cider, etc.). Acetic-acid-based substitutes are synthetically produced and, under FDA standards, generally cannot be labeled simply as 'vinegar' without qualification. Importers of synthetic substitutes should confirm FDA labeling compliance before entry to avoid detention.
