Products classified under HTS 2915.50.50.00
Sodium Propionate
Sodium propionate is the sodium salt of propionic acid, a saturated acyclic monocarboxylic acid. It falls under HTS 2915.50.50.00 as a salt of propionic acid not specifically provided for elsewhere in the subheading. Commonly used as a food preservative to inhibit mold growth.
Isopropyl Propionate
Isopropyl propionate is an ester formed from propionic acid and isopropanol, used as a flavoring agent and solvent. Falls under HTS 2915.50.50.00 as an 'other' ester of propionic acid per chapter note A on ester classification. Clear, colorless liquid with fruity odor.
Methyl Propionate
Methyl propionate, the methyl ester of propionic acid, serves as an intermediate in pharmaceutical synthesis and flavor applications. HTS 2915.50.50.00 classification follows chapter note A, assigning esters to the parent acid heading occurring last numerically.
Propionic Anhydride
Propionic anhydride, (CH3CH2CO)2O, is the mixed anhydride of propionic acid used in acetylation reactions and pharmaceutical intermediates. Although the heading mentions anhydrides, this falls in 'other' as not specifically provided for. Highly reactive, pungent liquid.
Ethyl Propionate
Ethyl propionate (CH3CH2COOCH2CH3) is the ethyl ester of propionic acid used in fruit flavorings and as a printing ink solvent. Classified per chapter note B with the corresponding propionic acid heading. Colorless liquid with apple-like odor.
N-Propyl Propionate
N-propyl propionate is a short-chain ester used in coatings, adhesives, and as a flavor intermediate. HTS 2915.50.50.00 applies to this 'other' propionic acid ester following chapter ester classification rules. Low-odor, medium-evaporating solvent.
Ammonium Propionate
Ammonium propionate (NH4C2H5COO) serves as a dough conditioner and intermediate for other propionates. As a salt of propionic acid, classified under HTS 2915.50.50.00 per chapter note C(1) for organic salts. White crystalline solid.
Butyl Propionate
Butyl propionate (CH3CH2COOC4H9) functions as a lacquer solvent and fruit flavoring agent. This 'other' propionic acid ester falls under HTS 2915.50.50.00. Slow-evaporating, low-odor solvent for industrial coatings.
Calcium Propionate
Calcium propionate, the calcium salt of propionic acid, is widely used as an antimicrobial agent in bakery products. Classified under HTS 2915.50.50.00 as 'other' salts and esters of propionic acid. Meets chapter note requirements for inorganic salts of organic acids.
