Cream 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.

If sold as a food preparation or mixed with other ingredients
Blends containing cream of tartar with other substances for culinary use are classified as food preparations, not as argol.
If the product is unprocessed vegetable waste or residues from winemaking
Raw wine lees that have not been purified or processed into argol may fall under heading 23.08 for vegetable materials used in animal feeding.

Import Tips & Compliance
• Ensure the product is classified as argol or wine lees, not as a prepared food additive, which may fall under a different heading
• Keep records of the winemaking origin to support the tariff classification if questioned by CBSA
• Verify whether the powder is purified or blended, as added binders or other ingredients could change the classification
