U.S. imports of Heterocyclic Compounds with Unfused Furan Ring (NESOI) (HS 293219) totaled $3.2M in August 2026, imported from 22 countries.
Importers of Heterocyclic Compounds with Unfused Furan Ring (NESOI) paid $711K in duties in August 2026, an average duty rate of 21.69% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Heterocyclic Compounds with Unfused Furan Ring (NESOI) imports of $3.2M in August 2026 ran 43% below the year-to-date monthly average of $5.6M.
Last updated: August 2026 dataCompounds containing an unfused furan ring system — excluding furfural and other specifically enumerated furans — are classified here and split across three US tariff lines: a general NESOI line (2932190002), aromatic compounds with an unfused furan ring in the structure (2932191000), and non-aromatic counterparts (2932195100). China dominates US import supply, followed by Japan and India, reflecting the concentration of fine-chemical and pharmaceutical intermediate manufacturing in Asia. Many of these compounds serve as building blocks in agrochemical, pharmaceutical, and specialty polymer synthesis, making correct aromatic/non-aromatic classification critical to duty determination. Importers should confirm whether a specific compound falls under a more specific HS6 provision before defaulting to this NESOI heading.

The US schedule distinguishes aromatic or modified-aromatic furan-ring compounds (2932191000) from non-aromatic ones (2932195100). The classification turns on whether the compound's furan ring is fused to an aromatic ring system or otherwise meets the aromatic/modified-aromatic definition under the HTS General Rules. A licensed customs broker or chemist familiar with IUPAC nomenclature should review the structural formula before filing.
Yes — furfural (furan-2-carbaldehyde), furfuryl alcohol, tetrahydrofurfuryl alcohol, and several other specifically named furan derivatives have their own dedicated HS subheadings earlier in Chapter 29. Only compounds not more specifically provided for elsewhere fall into this NESOI provision.
