Products classified under HTS 2915.50.20.00
Aromatic Propionic Acid Ester (Ethyl 3-Phenylpropanoate)
Ethyl 3-phenylpropanoate is an aromatic ester of propionic acid where the propyl chain is substituted with a phenyl group, making it aromatic. It falls under HTS 2915.50.20.00 as an 'aromatic' derivative of propionic acid ester per Chapter 29 notes on classification by numerical order. Used in flavorings and fragrances for its fruity aroma.
Hydrocinnamic Acid Methyl Ester
Methyl 3-phenylpropanoate, aka hydrocinnamic acid methyl ester, is an aromatic propionic acid ester used in synthetic rose and honey fragrances. Classified under HTS 2915.50.20.00 as 'aromatic' per the propionic acid subheading and Chapter 29 priority rules. Its phenyl substitution qualifies it as aromatic within this specific code.
Phenethyl Propionate
Phenethyl propionate, an ester with phenyl-ethyl and propionate groups, serves in floral fragrance compositions. Classified in HTS 2915.50.20.00 as aromatic under propionic esters due to the defining acid chain and aromatic substitution. Adheres to Chapter 29 isomer and derivative rules.
Methyl Hydrocinnamate
Methyl hydrocinnamate (methyl 3-phenylpropanoate) is a key intermediate in aroma chemical synthesis. It qualifies for HTS 2915.50.20.00 as an aromatic propionic acid ester, with the phenylpropane chain meeting the saturated acyclic criteria. Chapter notes ensure proper placement over alcohol headings.
Isobutyl 3-Phenylpropanoate
Isobutyl ester of 3-phenylpropanoic acid, used in specialty flavors mimicking tropical fruits. Falls under HTS 2915.50.20.00 as aromatic propionic ester, confirmed by chemical definition in Chapter notes (a). The aromatic substitution distinguishes it from plain propionates.
Cinnamic Acid Propyl Ester
Propyl cinnamate is an ester derived from aromatic propionic acid structures, used in cosmetics and as a fixative in perfumes. It fits HTS 2915.50.20.00 as an aromatic ester of propionic acid equivalents, following Chapter 29's last-in-order rule for overlapping compounds. The aromatic ring defines its subheading placement.
Benzyl Propionate
Benzyl propionate is the benzyl ester of propionic acid, featuring an aromatic benzyl group, used in fruit flavor formulations. HTS 2915.50.20.00 covers it as an aromatic propionic ester under the saturated acyclic monocarboxylic acids subchapter. Chapter notes confirm ester classification follows the acid component.
