Products classified under HTS 2307.00.00.00
Cream of Tartar Powder
Cream of tartar, or potassium bitartrate, is a purified form of argol derived from wine lees during winemaking. It falls under HTS 2307.00.00.00 as argol, the crystalline deposit left after wine fermentation. Commonly used as a baking acid and stabilizer in food products.
Raw Wine Lees
Raw wine lees consist of the sediment from fermented wine, including yeast, grape skins, and tartrates. Classified under HTS 2307.00.00.00 as wine lees, a direct byproduct of winemaking. Used in animal feed, composting, or extraction of tartaric acid.
Argol Crystals
Argol crystals are the natural potassium hydrogen tartrate deposits formed on wine barrel walls during aging. This product is explicitly covered by HTS 2307.00.00.00 as argol from wine lees. Primarily exported for tartaric acid production.
Dried Wine Lees Pellets
Dried wine lees formed into pellets for easier handling and transport, retaining the characteristic yeast and tartrate composition. Remains classified under HTS 2307.00.00.00 as it represents minimally processed wine lees. Common in organic fertilizer production.
Potassium Bitartrate Argol
Commercial potassium bitartrate argol, scraped from wine vats, used directly in winemaking for acidification. HTS 2307.00.00.00 covers this specific wine industry byproduct. Key ingredient in stabilizing white wines.
Wine Vat Argol Scrapings
Crude argol scrapings directly from wine fermentation vats, containing natural tartrate crystals. Classified under HTS 2307.00.00.00 as the classic form of argol from wine lees. Sold to chemical processors for refinement.
Food-Grade Argol
Specially cleaned argol meeting food safety standards, derived from white wine production. Still classified under HTS 2307.00.00.00 as it remains argol, not chemically altered. Used in baking powder and confectionery.
Fermentation Lees Sediment
Wet sediment collected from wine fermentation tanks, primarily yeast lees with tartrates. HTS 2307.00.00.00 includes all forms of wine lees regardless of moisture. Used for biogas production and soil amendment.
