Products classified under Tariff item 2932.19.00
2,5-Furandicarboxylic Acid
2,5-Furandicarboxylic acid (FDCA) is a bio-based aromatic diacid with an unfused furan ring, used as a key monomer for producing polyethylene furanoate (PEF), a sustainable alternative to PET. Its structure contains only oxygen hetero-atoms in the heterocyclic ring, qualifying it under tariff item 2932.19.00 as an 'Other' heterocyclic compound with oxygen hetero-atoms only.
2-Acetylfuran
2-Acetylfuran is an aromatic ketone with an unfused furan ring, used to impart caramel flavors in food products. The ketone substituent does not introduce additional hetero-atoms, and the ring contains only oxygen, placing it under tariff item 2932.19.00 as an 'Other' furan compound.
2-Furaldehyde Diethyl Acetal
2-Furaldehyde diethyl acetal is a protected form of furfural, used in organic synthesis, retaining the aromatic furan ring with only oxygen hetero-atoms. It is a separate chemically defined compound, classifiable under tariff item 2932.19.00 as an 'Other' heterocyclic compound.
2-Furanmethanol Acetate
2-Furanmethanol acetate is the acetate ester of furfuryl alcohol, maintaining the aromatic furan ring. Used in flavor chemistry and polymer production, it is a separate chemically defined compound with only oxygen hetero-atoms in the ring, falling under tariff item 2932.19.00.
2-Furoic Acid
2-Furoic acid is an aromatic carboxylic acid with an unfused furan ring, used in pharmaceuticals and as a preservative. The ring contains only oxygen hetero-atoms, and the compound is chemically defined, qualifying under tariff item 2932.19.00 as 'Other'.
3-Furoic Acid
3-Furoic acid is an aromatic carboxylic acid with the carboxyl group at position 3 of the furan ring, used in pharmaceutical intermediates. It is a separate chemically defined compound with only oxygen hetero-atoms in the ring, falling under tariff item 2932.19.00.
5-Hydroxymethylfurfural
5-Hydroxymethylfurfural (HMF) is a platform chemical derived from sugar dehydration, featuring an aromatic furan ring with aldehyde and alcohol functions. It is a separate chemically defined compound with only oxygen hetero-atoms in the ring, qualifying under tariff item 2932.19.00.
5-Methylfurfural
5-Methylfurfural is a naturally derived aromatic aldehyde with an unfused furan ring, used in flavorings and fragrances. The methyl substituent does not add hetero-atoms, and the ring contains only oxygen, placing it under tariff item 2932.19.00 as 'Other'.
5-Nitro-2-Furaldehyde
5-Nitro-2-furaldehyde contains a nitro group on the aromatic furan ring, used in antimicrobial synthesis. Per Chapter Note 4, nitro groups are not considered nitrogen functions, so the compound remains in heading 2932 with only oxygen hetero-atoms in the ring, under tariff item 2932.19.00.
Furan-2,5-Dione
Furan-2,5-dione, also known as maleic anhydride's furan analog, contains an aromatic unfused furan ring with an anhydride functionality. It is used in specialty polymers, and since the ring has only oxygen hetero-atoms, it falls under tariff item 2932.19.00 as 'Other'.
Furan-2-Methanol
Furan-2-methanol, also known as furfuryl alcohol, contains an aromatic unfused furan ring with a hydroxymethyl group, widely used in resin production and fragrances. The ring has only oxygen hetero-atoms, qualifying under tariff item 2932.19.00 as 'Other'.
Furfural
Furfural is an aromatic heterocyclic compound with an unfused furan ring, derived from agricultural byproducts like corncobs. It serves as a key intermediate in resins, plastics, and flavorings, and since the ring has only oxygen hetero-atoms, it falls under tariff item 2932.19.00.
Furfurylamine
Furfurylamine is an aromatic furan derivative with an amine substituent on the unfused ring, used in polymer synthesis and agrochemicals. The ring contains only oxygen hetero-atoms, and per Chapter Note 4, the amine is not a nitrogen function for classification, so it falls under tariff item 2932.19.00.
Methyl 2-Furoate
Methyl 2-furoate is the methyl ester of 2-furoic acid, an aromatic furan compound used in flavors and fragrances. Per Chapter Note 5, esters are classified with the parent acid, so it falls under tariff item 2932.19.00 as 'Other'.
Tetrahydrofurfuryl Alcohol
Tetrahydrofurfuryl alcohol features a hydrogenated furan ring (tetrahydrofuran structure) with a hydroxymethyl group, used as a green solvent in coatings and pharmaceuticals. Although hydrogenated, it is classified as a furan derivative with only oxygen hetero-atoms, under tariff item 2932.19.00.
