U.S. imports of Saturated Fluorinated Derivatives of Acyclic Hydrocarbons (Other) (HS 290349) totaled $2.1M in August 2026, imported from 6 countries.
Importers of Saturated Fluorinated Derivatives of Acyclic Hydrocarbons (Other) paid $279K in duties in August 2026, an average duty rate of 13.47% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Saturated Fluorinated Derivatives of Acyclic Hydrocarbons (Other) imports of $2.1M in August 2026 ran 57% above the year-to-date monthly average of $1.3M.
Last updated: August 2026 dataPerfluorocarbons (PFCs) and other fully or partially saturated fluorinated acyclic compounds not enumerated elsewhere in the schedule fall under tariff line 2903490000 — a catch-all that captures a broad range of specialty fluorochemicals used in semiconductor etching gases, heat-transfer fluids, and surface-treatment agents. Japan and China are the leading US suppliers, with the United Kingdom, France, and India also contributing. The diversity of compounds within this residual heading means classification disputes are common; importers should document chemical identity precisely to avoid misclassification into a more specific HTS line.

The more specific HFC subheadings (e.g., 290346, 290347, 290348) enumerate named compounds by chemical identity. A saturated fluorinated acyclic hydrocarbon that does not match any of those named compounds — such as certain perfluoroalkanes or novel fluorinated intermediates — falls into this residual 2903490000 line. Importers should obtain a precise CAS number and IUPAC name and confirm no named subheading applies before using this catch-all.
Some perfluorocarbons classified here are listed as high-GWP greenhouse gases subject to EPA Greenhouse Gas Reporting Program (GHGRP) requirements for certain industrial emitters. Additionally, if a compound qualifies as an HFC under the AIM Act's definition, it may be subject to phasedown allocations. Importers should verify the regulatory status of each specific compound with EPA before finalizing supply arrangements.
