Wine lees are the sediment deposited in wine vessels during fermentation and aging, while argol (crude tartar) is the raw potassium bitartrate crust that forms on the interior of wine casks — both classified together under HTS 2307000000. These materials are the primary natural source of tartaric acid and cream of tartar, making them an input for the food, pharmaceutical, and chemical industries rather than a conventional feed commodity. Japan and Italy are the recorded US import sources under this heading, with Italy's position reflecting its status as one of the world's largest wine producers. The relatively narrow supplier base and specialized downstream uses make this a niche but commercially stable trade flow.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Argol is refined into cream of tartar (potassium bitartrate) and tartaric acid, which are used as food acidulants, baking stabilizers, and pharmaceutical excipients. Wine lees may also be processed to recover residual alcohol or tartrates. The downstream refining industry — not direct food or feed use — is the primary commercial driver for these imports.
Because wine lees and argol are typically imported as industrial raw materials for further processing rather than as finished food ingredients, FDA oversight at entry is generally limited. However, if a shipment is destined for direct use as a food additive or ingredient without further refining, FDA food safety requirements would apply. Importers should clarify the intended end use with their customs broker to determine applicable admissibility requirements.
