2826.90.90.10 - Lithium hexafluorophosphate

This HTS code, 2826.90.90.10, specifically identifies Lithium hexafluorophosphate (LiPF6). This compound is a critical inorganic salt and a key component in the electrolyte formulations for rechargeable lithium-ion batteries. Its primary function is to facilitate the movement of lithium ions between the anode and cathode during charging and discharging cycles.

As a specific lithium compound within the broader category of "Other" complex fluorine salts under 2826.90, this classification distinguishes LiPF6 from other miscellaneous fluorides and complex fluorine salts that do not contain lithium as their primary cationic component. While other complex fluorine salts may share similar chemical structures, the presence and specific role of lithium in LiPF6 necessitate its distinct classification for trade purposes.

The subcategory 2826.90.90.90, "Other," exists to capture any remaining complex fluorine salts not otherwise specified, further emphasizing that 2826.90.90.10 is reserved solely for Lithium hexafluorophosphate. This hierarchical structure ensures precise tariff application based on the chemical composition and intended use of these specialized inorganic compounds.
