Subheadings
Products classified under Tariff item 2918.14.00
Anhydrous Citric Acid
Anhydrous citric acid (C6H8O7) is a tricarboxylic acid with an alcohol function and no other oxygen function, matching the description of tariff item 2918.14.00. It is a separate chemically defined organic compound, as required by Chapter Note 1(a). Used widely as an acidulant, preservative, and pH regulator in food and beverage applications.
Buffered Citric Acid Solution 10%
A 10% citric acid solution with a minimal buffering stabilizer is classified under tariff item 2918.14.00 as a solution of a chemically defined compound. The stabilizer is added solely for preservation or transport, as permitted by Chapter Note 1(f), and does not make the product suitable for a specific use. It is used for precise pH control in laboratory and biotech applications.
Citric Acid 50% Aqueous Solution
A 50% aqueous solution of citric acid falls under tariff item 2918.14.00 as a solution of a chemically defined compound in water, per Chapter Note 1(d). It is used in cleaning formulations and as an intermediate for further dilution in food processing. The water does not alter the chemical identity of the citric acid.
Citric Acid for Beverage Industry
High-purity citric acid for the beverage industry is classified under tariff item 2918.14.00 as the chemically defined compound. It is used for acidification and preservation in sodas, sports drinks, and juices, providing tartness and stability. The product's intended use does not affect classification as it is the pure compound.
Citric Acid for Cosmetics
Cosmetic-grade citric acid for pH adjustment in lotions, shampoos, and peels is classified under tariff item 2918.14.00 as the pure organic compound. High purity ensures skin safety and formulation stability. The cosmetic use does not alter the chemical classification of the compound.
Citric Acid for Wine Making
Food-grade citric acid for wine making is classified under tariff item 2918.14.00 as the pure compound. It is used for acidification and deacidification in must and wine production, adjusting pH and chelating excess metals. The oenological use does not change the chemical classification.
Citric Acid Monohydrate USP Grade
Citric acid monohydrate (C6H8O7·H2O) is classified under tariff item 2918.14.00 as the hydrated form of the pure compound. The water of crystallization does not change the chemical identity. USP grade meets pharmaceutical standards for use in various applications.
Citric Acid Technical Grade
Technical grade citric acid (99% purity) for industrial uses like detergents and metal cleaning is classified under tariff item 2918.14.00. Lower purity than food or pharmaceutical grades still meets the definition of a chemically defined compound. The product's industrial use does not affect classification.
Citric Acid with Anti-Dusting Agent
Citric acid treated with a minimal anti-dusting agent (e.g., mineral oil below 0.1%) is classified under tariff item 2918.14.00 per Chapter Note 1(g). The additive is for safety and identification purposes only and does not render the product suitable for a specific use. It is used in bulk handling for food processing where dust control is essential.
Effervescent Citric Acid Base
Pure citric acid for effervescent formulations is classified under tariff item 2918.14.00 when imported separately. It provides the acid reaction for tablets and powders used in vitamin supplements and antacids. The product is the chemically defined compound, not a preparation.
Food-Grade Citric Acid Powder
Food-grade citric acid powder meeting FCC standards is classified under tariff item 2918.14.00 as the pure compound. It is used as a souring agent in soft drinks, candies, and confections. The physical form (powder) does not affect classification.
Granular Citric Acid with Stabilizer
Granular citric acid with a minimal stabilizer (anti-caking agent) is classified under tariff item 2918.14.00 per Chapter Note 1(f). The stabilizer is necessary for preservation or transport and does not render the product suitable for a specific use. It is ideal for long-term storage and bulk handling.
High-Purity Citric Acid for Metal Passivation
Ultra-pure citric acid (99.9%) for metal passivation in aerospace and medical device manufacturing is classified under tariff item 2918.14.00. It acts as an eco-friendly alternative to nitric acid for stainless steel treatment. The high purity confirms it is the separate chemically defined compound.
Organic Citric Acid Crystals
Crystalline citric acid produced via organic fermentation is classified under tariff item 2918.14.00 as the identical chemical compound regardless of production process. Organic certification does not change the chemical structure. It is used in premium organic beverages and foods.
Pharmaceutical Citric Acid Anhydrous BP
BP-grade anhydrous citric acid for pharmaceutical applications is classified under tariff item 2918.14.00 as the pure tricarboxylic acid with alcohol function. It is used as a buffering agent in injectables and effervescent formulations. The pharmaceutical grade confirms high purity and compliance with standards.
