SITCSection 5
U.S. imports of acyclic ketones without other oxygen function, n.e.s. (SITC 51625) totaled $4.4M in April 2026, traded with 18 countries.
Importers of Acyclic Ketones Without Other Oxygen Function, N.E.S. paid $380K in duties in April 2026 — an effective duty rate of 9.4% on $4.0M in dutiable value, based on actual customs collections rather than the published tariff schedule. Acyclic Ketones Without Other Oxygen Function, N.E.S. imports of $4.4M in April 2026 ran 50% above the year-to-date monthly average of $3.0M.
Last updated: April 2026 dataAcyclic ketones not elsewhere specified form a residual catch-all for open-chain ketone compounds that lack additional oxygen-bearing functional groups and do not fall under named headings such as butanone or acetone. Correct classification within this NES grouping often requires detailed chemical documentation — including CAS numbers and structural confirmation — because misclassification into a named ketone heading can alter duty exposure and Section 301 applicability. These compounds serve diverse industrial roles as solvents, fragrance intermediates, and chemical synthesis building blocks.

Importers generally need to provide a technical data sheet, the compound's CAS registry number, and a structural formula confirming the absence of additional oxygen functions. A binding ruling from CBP can provide certainty when the compound's classification between a named heading and the NES residual is ambiguous.
Section 301 tariff applicability depends on the specific HTS subheading assigned at the 10-digit level and the country of origin. Importers sourcing from China should verify the applicable HTS code and check the current USTR Section 301 product list, as coverage within broad chemical NES categories can vary by line.
