U.S. imports of fluoroaluminates & other fluorine salts (not elsewhere specified) (HS 282690) totaled $10.5M in April 2026, traded with 10 countries.
Importers of Fluoroaluminates & Other Fluorine Salts (Not Elsewhere Specified) paid $349K in duties in April 2026 — an effective duty rate of 4.0% on $8.8M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataLithium hexafluorophosphate (LiPF₆), the electrolyte salt central to lithium-ion battery manufacturing, is one of the highest-value products in this heading and has its own dedicated 10-digit line (2826909010), reflecting its strategic importance to the EV and energy-storage supply chain. China and South Korea are the top suppliers, consistent with their dominant positions in battery materials production. The residual line (2826909090) captures a wide range of other fluoroaluminates and complex fluorine salts used in specialty glass, ceramics, and surface-treatment applications. Given China's leading role, importers should assess Section 301 exposure for each specific product within this heading.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
LiPF₆ is singled out at the 10-digit level (2826909010) because of its critical role as the primary electrolyte salt in lithium-ion batteries. All other fluoroaluminates and complex fluorine salts not specifically named fall to the basket line 2826909090. The distinction matters for Section 301 tariff analysis and for supply-chain compliance programs tied to battery-critical minerals.
China and South Korea together account for the bulk of US imports, particularly for battery-grade LiPF₆. Japan and Germany supply higher-purity specialty grades used in optics and surface treatment. This concentration in China creates Section 301 tariff exposure and has prompted some importers to qualify South Korean and Japanese alternative sources as part of supply-chain risk management.
