HS Code for Propionates

Propionates, which include the salts and esters of propionic acid, are classified under Chapter 29 of the Harmonized System, dedicated to organic chemicals. Specifically, they fall under Heading 2915, which covers saturated acyclic monocarboxylic acids and their anhydrides, halides, peroxides, and peroxyacids, as well as their halogenated, sulfonated, nitrated, or nitrosated derivatives. Subheading 2915.50 is the specific category for propionic acid, its salts, and its esters. This classification is based on the molecular structure of the compound, which features a three-carbon chain. Under the Harmonized System's General Rules for Interpretation, the chemical identity as a derivative of a saturated acyclic monocarboxylic acid is the primary factor for its placement. Propionates are essential in the food industry as antimicrobials and in the chemical industry for the production of plastics and perfumes. The classification remains consistent for these compounds as long as they are imported as separate chemically defined organic substances, regardless of their intended end-use in food or industry.

Products Included

• Calcium propionate (commonly used as a bread preservative)
• Sodium propionate
• Ethyl propionate (an ester used in fragrances)
• Methyl propionate
• Propionic acid in its pure form

Common Misclassification

Propionates are often misclassified under HS code 2915.70, which covers palmitic acid, stearic acid, and their salts and esters, or under 2915.90, which is a residual category for other saturated acyclic monocarboxylic acids. Confusion also arises with acetates (2915.39) due to their similar use in industrial applications. It is vital to identify the specific carbon chain length; propionates always have three carbons, whereas acetates have two, which dictates the specific subheading within 2915.

FAQ

What is the HS code for propionates?

The HS code for propionates, including propionic acid and its salts or esters, is 2915.50.

Does the HS code change for food-grade calcium propionate?

No, calcium propionate used as a food additive is still classified under 2915.50 as it is a salt of propionic acid.
