Last updated: April 2026 dataServing as the broadest residual category within heading 3827, this subheading covers halogenated hydrocarbon mixtures — including blends of chlorinated, brominated, or fluorinated methane, ethane, and propane derivatives — that are not captured by any more specific provision. The US tariff schedule subdivides this heading into three 10-digit lines: 3827900000, 3827901000, and 3827909000, the last of which covers mixtures of two or more halogenated acyclic hydrocarbon derivatives. Switzerland, Israel, and Canada lead US supply, reflecting the importance of specialty chemical and pharmaceutical manufacturing in those markets. Canadian-origin goods may qualify for USMCA preferential treatment.

Tariff line 3827901000 covers mixtures containing halogenated derivatives of methane, ethane, or propane in a more specific formulation context, while 3827909000 is reserved for mixtures of two or more halogenated acyclic hydrocarbon derivatives not elsewhere specified. Line 3827900000 serves as the catch-all within the subheading. Importers should review the CBP classification instructions and, where the blend composition is complex, consider a binding ruling to confirm the correct 10-digit line.
Yes. Blends containing ozone-depleting substances such as methyl bromide or certain chlorinated solvents may be subject to EPA import restrictions under the Clean Air Act's Title VI provisions, separate from the HFC allowance framework. Additionally, some brominated compounds trigger TSCA reporting or significant new use rules. Importers should identify each halogenated component and verify applicable EPA and TSCA obligations before entry.
