U.S. imports of Aluminum Fluoride (HS 282612) totaled $3.1M in August 2026, imported from 7 countries.
Importers of Aluminum Fluoride paid $6K in duties in August 2026, an average duty rate of 0.18% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Aluminum Fluoride imports of $3.1M in August 2026 ran 10% above the year-to-date monthly average of $2.8M.
Last updated: August 2026 dataAluminum fluoride is an essential flux additive in primary aluminum smelting, where it lowers the melting point of the alumina-cryolite bath and improves electrical efficiency in the Hall-Héroult process. Mexico leads US import supply under tariff line 2826120000, followed by China and Sweden — a supplier mix that reflects both geographic proximity and the location of major fluorochemical producers. Imports from China may be subject to Section 301 tariffs, making Mexican and European sources commercially attractive alternatives. The product is also used in the production of specialty ceramics and as a catalyst in certain organic fluorination reactions, though the smelting application dominates trade volumes.

No — aluminum fluoride (AlF₃) and cryolite (sodium aluminum fluoride, Na₃AlF₆) are chemically distinct compounds and classified separately. Aluminum fluoride falls under 2826120000, while synthetic cryolite is classified under a different subheading in Chapter 28. Both are used in aluminum smelting, but they serve different functions in the electrolytic bath and are not interchangeable for classification purposes.
A certificate of analysis confirming the chemical formula (AlF₃), fluoride content, and purity grade is the standard supporting document. This is important because aluminum fluoride must be distinguished from aluminum hydroxyfluorides or mixed fluoride salts, which may classify differently. The CAS number (7784-18-1 for anhydrous AlF₃) should be referenced on the commercial invoice to reduce the risk of a CBP query at entry.
