2826.90.90.90 - Other

This HTS category, 2826.90.90.90, specifically classifies lithium hexafluorophosphate. Lithium hexafluorophosphate is an inorganic salt with the chemical formula LiPF₆. It is a white, crystalline solid and is primarily recognized for its critical role as an electrolyte salt in lithium-ion batteries. Its high conductivity and electrochemical stability make it an essential component in powering rechargeable batteries used in a wide range of electronic devices and electric vehicles.

Given that this is a specific classification for lithium hexafluorophosphate, there are no sibling categories at this exact level within the HTS structure that would require distinction. The parent category, "Other" under "Fluorides; fluorosilicates, fluoroaluminates and other complex fluorine salts," broadly encompasses a variety of fluorine-containing inorganic compounds. This specific subcategory isolates lithium hexafluorophosphate, allowing for precise tariff treatment.

As this HTS code represents a leaf node, there are no further subcategories. The classification is highly specific, meaning that any product fitting the description of lithium hexafluorophosphate, regardless of minor variations in purity or physical form (e.g., powder, granules), would fall under this HTS number. The key defining characteristic for classification here is the chemical identity: lithium hexafluorophosphate.
