U.S. imports of Fluorides, Fluorosilicates, Fluoroaluminates, and Other Complex Fluorine Salts (SITC 52310) totaled $21.7M in August 2026, imported from 30 countries.
Importers of Fluorides, Fluorosilicates, Fluoroaluminates, and Other Complex Fluorine Salts paid $1.8M in duties in August 2026, an average duty rate of 8.07% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Fluorides, Fluorosilicates, Fluoroaluminates, and Other Complex Fluorine Salts imports of $21.7M in August 2026 ran 16% above the year-to-date monthly average of $18.7M.
Last updated: August 2026 dataFluorine salts in this heading span a wide industrial spectrum: aluminum fluoride and cryolite (sodium hexafluoroaluminate) are essential fluxes in primary aluminum smelting, while ammonium bifluoride and sodium fluoride serve in metal surface treatment, glass etching, and wood preservation. The complex fluorine salts — fluorosilicates and fluoroaluminates — are often byproducts of phosphate fertilizer or aluminum production, giving their trade flows a close linkage to those upstream industries. Importers should be aware that certain fluoride compounds are regulated under EPA's Toxic Substances Control Act and may require TSCA certification at entry.

255 import shipments a month
Both cryolite (natural and synthetic) and aluminum fluoride are consumed as bath additives in Hall-Héroult electrolytic cells to lower the melting point of alumina and improve electrical conductivity. Demand tracks primary aluminum production capacity; smelters typically maintain strategic inventories, so import volumes can fluctuate with production schedules and bath chemistry adjustments.
Many fluoride compounds are listed on the TSCA chemical inventory, and importers must certify compliance — either that the substance is on the TSCA inventory or that it is exempt — on CBP Form 3540 or equivalent. Certain fluorides also carry EPA Reportable Quantity designations under CERCLA, so spill-response planning and SDS documentation should be in order before the shipment arrives.
