Products classified under HTS 2918.13.20.00
Food-Grade Potassium Bitartrate Powder
Pure potassium bitartrate, commonly known as cream of tartar, is a natural byproduct of winemaking used as a food additive for stabilizing egg whites and preventing sugar crystallization in candies. This specific HTS code 2918.13.2000 classifies it as the potassium salt of tartaric acid with alcohol function but no other oxygen functions, meeting Chapter 29 requirements for separate chemically defined organic compounds. It's supplied as a fine white crystalline powder for culinary applications.
USP-Grade Cream of Tartar Crystals
Pharmaceutical-grade potassium bitartrate meeting USP standards for use in compounding prescriptions and as a laxative or antacid ingredient. Classified under HTS 2918.13.2000 as the specific potassium salt of tartaric acid per Chapter 29 note (A) for salts of acid-function compounds. Supplied in crystalline form with stabilizer for purity preservation during transport.
Winemaking Potassium Bitartrate Precipitate
Technical-grade cream of tartar recovered from wine fermentation, used to adjust acidity and stabilize wines by precipitating excess tartrates. Falls precisely under HTS 2918.13.2000 as potassium bitartrate, a carboxylic acid salt with alcohol function per Chapter 29 definitions. Typically imported in 25kg bags with anti-dusting agent for safe handling.
Bulk Baking Stabilizer Potassium Bitartrate
Industrial food processing grade cream of tartar in bulk 50lb sacks for meringue production and candy manufacturing. HTS 2918.13.2000 applies to this chemically defined potassium salt of tartaric acid with alcohol function, allowable with transport stabilizer per Chapter 29 note (f). Purity exceeds 99.7% for consistent performance.
Pharma-Intermediate Cream of Tartar Granules
Granulated potassium bitartrate serving as intermediate for API synthesis in antacid formulations and effervescent tablets. Strictly classified under HTS 2918.13.2000 as the pure salt per Chapter 29 note (C)(1) for organic salts. Includes minimal stabilizer for transport stability.
Purified Wine Tartrate Potassium Salt
Refined potassium bitartrate from grape wine lees, certified organic for natural wine acidification. HTS 2918.13.2000 covers this as chemically defined organic salt with alcohol function, post Chapter 29 purification criteria. Supplied dust-free with identification odorant.
Technical-Grade Cream of Tartar for Candymaking
Technical purity potassium bitartrate (99% min) for commercial sugar confectionery to inhibit crystallization. Precisely HTS 2918.13.2000 as potassium salt of tartaric acid per Chapter 29 numerical order for salts. Bulk powder with anti-caking for industrial transport.
