Anhydrous Citric Acid
Pure anhydrous citric acid (C6H8O7) is a tricarboxylic acid with alcohol function but no other oxygen function, directly matching HTS 2918.14.00.00. It is widely used as an acidulant, preservative, and pH regulator in food and beverages. This classification applies to the chemically defined organic compound in its pure form.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended with anticaking agents exceeding stabilizer limits
Mixtures not qualifying as chemically defined compounds with mere stabilizers fall under chemical preparations.
If incorrectly identified as another carboxylic acid with alcohol function
Chapter notes require classification in the specific citric acid subheading when matching the chemical definition.

Import Tips & Compliance
• Verify purity certificate (≥99%) and ensure COA confirms anhydrous form to avoid reclassification as mixtures
• Provide detailed end-use documentation; food-grade requires FDA prior notice and compliance with 21 CFR 184.1033

Citric Acid Monohydrate USP Grade
Citric acid monohydrate (C6H8O7·H2O) retains the core tricarboxylic acid structure with alcohol function, classified under HTS 2918.14.00.00 as the hydrated form of the pure compound. USP grade meets pharmaceutical standards for purity and is used in effervescent tablets and syrups. The water of hydration does not alter its classification per chapter notes.
Pharmaceutical Citric Acid Anhydrous BP
BP-grade anhydrous citric acid for pharmaceutical applications is classified under HTS 2918.14.00.00 due to its pure tricarboxylic acid with alcohol function. Used as buffering agent in injectables, effervescent formulations, and vitamin C production. British Pharmacopoeia standards confirm its status as a separate chemically defined compound.
Granular Citric Acid with Stabilizer
Granular citric acid with added stabilizer (per note f) for preservation during transport remains under HTS 2918.14.00.00. The anticaking agent is minimal and necessary, not rendering it for specific use. Ideal for long-haul shipments to baking and confectionery industries.
Citric Acid Technical Grade
Technical grade citric acid (99% purity) for industrial uses like detergents and metal cleaning is classified under HTS 2918.14.00.00 as the chemically defined compound. Lower purity than food/pharma grades but still meets chapter note (a) for separate organic compounds with impurities.
Effervescent Citric Acid Base
Pure citric acid component for effervescent formulations (combined with bicarbonate) classified under HTS 2918.14.00.00 when imported separately. Provides the acid reaction for tablets and powders used in vitamin supplements. Remains a separate chemically defined compound.
Citric Acid for Cosmetics
Cosmetic-grade citric acid used for pH adjustment in lotions, shampoos, and peels falls under HTS 2918.14.00.00 as the pure organic compound with alcohol function. High purity ensures skin safety and stability in formulations.
