U.S. imports of monophenols, not elsewhere specified or included (HS 290719) totaled $1.6M in April 2026, traded with 16 countries.
Importers of Monophenols, Not Elsewhere Specified or Included paid $335K in duties in April 2026 — an effective duty rate of 22% on $1.5M in dutiable value, based on actual customs collections rather than the published tariff schedule. Monophenols, Not Elsewhere Specified or Included imports of $1.6M in April 2026 ran 44% below the year-to-date monthly average of $2.9M.
Last updated: April 2026 dataSpanning alkylcresols (2907191000), alkylphenols (2907192000), thymol (2907194000), xylenols and their salts (2907197000), and several other specialized phenolic compounds, this residual monophenol heading serves a wide range of end-use sectors including flavors and fragrances, antioxidant additives, and pharmaceutical synthesis. India leads US import supply, followed by Germany and China. The breadth of the heading means classification disputes can arise at the boundary with more specific headings — for example, distinguishing alkylphenols from the separately enumerated octylphenol/nonylphenol heading (290713) requires careful review of carbon-chain length and substitution pattern. Chinese-origin goods are subject to Section 301 tariffs.

Heading 290713 specifically covers octylphenol, nonylphenol, and their isomers and salts. Alkylphenols with different carbon-chain lengths or substitution patterns that are not specifically enumerated elsewhere fall under the NESOI provisions of 290719. When the chain length or isomer identity is ambiguous, a binding ruling request to CBP is advisable.
Thymol is used primarily in oral-care products (mouthwash, toothpaste), pharmaceutical antiseptics, and as a natural pesticide active ingredient. Its dual use across personal-care and agrochemical applications means buyers often require food-grade or pharmaceutical-grade certificates of analysis alongside standard commercial documentation.
