Importers of Sodium Hexafluoroaluminate (Synthetic Cryolite) paid $40K in duties in August 2026, an average duty rate of 4.09% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Sodium Hexafluoroaluminate (Synthetic Cryolite) imports of $982K in August 2026 ran 27% above the year-to-date monthly average of $770K.
Last updated: August 2026 dataSynthetic cryolite is the dominant flux used in primary aluminum smelting, lowering the melting point of alumina in electrolytic reduction cells and making it one of the most process-critical inorganic fluorine compounds in the metals industry. Classified entirely under a single 10-digit line (2826300000), it presents a straightforward classification profile but a concentrated supply picture: Canada leads US imports, followed by Denmark and Germany. Importers sourcing from Canada may benefit from USMCA preferential treatment, while European suppliers warrant attention to freight economics and any applicable trade-remedy exposure.

The HS nomenclature gives sodium hexafluoroaluminate its own six-digit heading (282630) because of its distinct and well-established industrial role as an aluminum smelting flux, distinguishing it from the broader fluoroaluminate and fluorine salt basket at 282690. Its single 10-digit US line (2826300000) means there is no further subdivision by grade or purity within the tariff schedule.
Canada is the leading supplier, and goods qualifying as originating under USMCA may be eligible for preferential duty treatment. Shipments from Denmark and Germany, the next-ranked sources, enter under normal trade relations rates. Importers should verify origin documentation carefully, as synthetic cryolite is often produced at integrated fluorochemical facilities where intermediate inputs may cross multiple borders.
