HS Code for Propionic acid

Propionic acid is classified under HS code 2915.50, which falls within the chapter for organic chemicals. Specifically, heading 29.15 covers saturated acyclic monocarboxylic acids and their derivatives. Propionic acid (also known as propanoic acid) is a naturally occurring carboxylic acid with the chemical formula C3H6O2. The classification 2915.50 is comprehensive, covering not only the pure acid but also its salts and esters. This is significant because salts like calcium propionate and sodium propionate are widely used in the food industry as preservatives to inhibit mold growth in baked goods. The classification is driven by the molecular structure of the substance; as a three-carbon chain acid, it follows acetic acid (2915.21) in the systematic arrangement of the Harmonized System. Whether the product is in a liquid state as a pure acid or a crystalline state as a salt, it remains under this subheading as long as it is a chemically defined organic compound. This ensures that industrial, food-grade, and pharmaceutical-grade versions of the chemical are tracked consistently across international borders.

Products Included

• Pure propionic acid (propanoic acid)
• Calcium propionate (food preservative)
• Sodium propionate
• Ethyl propionate (ester)
• Methyl propionate
• Potassium propionate

Common Misclassification

Propionic acid is sometimes misclassified under 29.15.21 (acetic acid) or 29.15.31 (ethyl acetate) due to similarities in chemical naming. Another common error is classifying the salts under 38.08 as prepared preservatives. However, according to Chapter 29 notes, a separate chemically defined compound remains in Chapter 29 even if it has a specific preservative function, unless it is put up in forms or packings for retail sale as a disinfectant or pesticide.

FAQ

What is the HS code for propionic acid?

The HS code for propionic acid, as well as its salts and esters, is 2915.50.

Are food-grade mold inhibitors classified here?

If the inhibitor is a pure salt like calcium propionate, it is classified under 2915.50. If it is a complex mixture of different preservatives, it may fall under 38.24.
