U.S. exports of Fluorinated, Brominated, or Iodinated Derivatives of Acyclic Hydrocarbons (SITC 51137) totaled $68.3M in August 2026.
Importers of Fluorinated, Brominated, or Iodinated Derivatives of Acyclic Hydrocarbons paid $2.6M in duties in August 2026, an average duty rate of 13.45% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Fluorinated, Brominated, or Iodinated Derivatives of Acyclic Hydrocarbons imports of $19.4M in August 2026 ran 21% below the year-to-date monthly average of $24.5M.
Last updated: August 2026 dataFluorinated acyclic derivatives — including hydrofluorocarbons (HFCs), hydrochlorofluorocarbons (HCFCs), and perfluorinated compounds — dominate this grouping and are subject to phasedown schedules under the AIM Act, which implements US obligations aligned with the Kigali Amendment to the Montreal Protocol. Brominated flame retardants and methyl bromide (a controlled fumigant) also fall within this category, each carrying distinct EPA and USDA APHIS regulatory requirements. Importers of HFCs must obtain EPA allowances under the AIM Act's consumption allowance system before bringing product into US commerce.

220 import shipments a month
Under the American Innovation and Manufacturing (AIM) Act, importers of bulk hydrofluorocarbons must hold sufficient EPA-issued consumption allowances to cover each shipment. Allowances are allocated annually and can be traded. Importing HFCs without the required allowances is a violation subject to civil penalties.
Methyl bromide is a Class I ozone-depleting substance controlled under the Clean Air Act and the Montreal Protocol. Imports for non-quarantine, non-pre-shipment uses are subject to strict EPA consumption allowances. USDA APHIS separately regulates its use as a quarantine fumigant, and importers must coordinate with both agencies depending on the intended application.
