Chapter 2307 — Customs Tariff Headings
Subheadings
Products classified under Tariff item 23.07
Argol Crystals
Argol crystals are natural potassium hydrogen tartrate deposits that form on wine barrel walls during aging. This product is explicitly covered by tariff item 2307.00.00 as argol, a direct byproduct of winemaking. It is primarily exported for tartar production and other industrial applications.
2307.00.00Cream of Tartar Powder
Cream of tartar powder, also known as potassium bitartrate, is a purified crystalline substance derived from wine lees, the sediment left after wine fermentation. As a form of argol, it retains the essential characteristics of the original winemaking by-product and is not further processed into a separate chemical compound. This product falls under tariff item 2307.00.00, which covers wine lees and argol in their natural or purified states.
2307.00.00Dried Wine Lees Pellets
Dried wine lees pellets are formed by compressing dried wine lees, retaining the characteristic yeast and tartrate composition. They are minimally processed and remain classified under tariff item 2307.00.00 as wine lees. The pellet form facilitates easier handling and transport.
2307.00.00Fermentation Lees Sediment
Fermentation lees sediment is wet sediment collected from wine fermentation tanks, primarily composed of yeast and tartrates. This product falls under tariff item 2307.00.00 as wine lees, regardless of moisture content. It is used for biogas production and soil amendment.
2307.00.00Food-Grade Argol
Food-grade argol is specially cleaned argol derived from white wine production, meeting food safety standards. It remains classified under tariff item 2307.00.00 as argol, as it is not chemically altered. This product is used in baking powder and confectionery applications.
2307.00.00Potassium Bitartrate Argol
Potassium bitartrate argol is commercial argol scraped from wine vats, used directly in winemaking for acidification. It is covered by tariff item 2307.00.00 as a specific wine industry byproduct. This product is a key ingredient in stabilizing white wines.
2307.00.00Raw Wine Lees
Raw wine lees consist of the sediment from fermented wine, including yeast, grape skins, and tartrates. They are classified under tariff item 2307.00.00 as wine lees, a direct byproduct of winemaking. This product is used in animal feed, composting, and other applications.
2307.00.00Wine Vat Argol Scrapings
Wine vat argol scrapings are crude argol scraped directly from wine fermentation vats, containing natural tartrate crystals. They are classified under tariff item 2307.00.00 as the classic form of argol from wine lees. This product is sold to chemical processors for refinement.
