HS Code for Lithium oxide

Lithium oxide and lithium hydroxide are classified under HS code 2825.20. This classification is governed by the rules of Chapter 28, which encompasses inorganic chemicals. Heading 2825 is designated for hydrazine and hydroxylamine and their inorganic salts, as well as other inorganic bases and other metal oxides, hydroxides, and peroxides. Subheading 2825.20 specifically identifies lithium oxide and hydroxide. These substances are primary lithium chemicals used extensively in the manufacture of lubricating greases, glass, and ceramics. The classification remains consistent for both the anhydrous form and the monohydrate form of lithium hydroxide (LiOH.H2O), as the Harmonized System treats these variations as the same basic chemical entity. The determination is based on the chemical identity of the substances as inorganic bases or metal oxides/hydroxides, following the specific provisions of the 6-digit international nomenclature.

Products Included

• Lithium hydroxide monohydrate
• Anhydrous lithium hydroxide
• Lithium oxide (Li2O)
• Technical grade lithium hydroxide for grease production
• High-purity lithium hydroxide for battery electrolyte synthesis

Common Misclassification

A common misclassification occurs with HS code 2836.91, which is reserved for lithium carbonate. Although both are essential lithium chemicals, their chemical structures are distinct. Another error involves HS code 3824.99, where prepared binders or chemical products are classified. If lithium hydroxide is mixed with other additives to form a specific industrial preparation, it may move to Chapter 38. Furthermore, lithium oxide is sometimes confused with lithium peroxide; while both fall under heading 2825, lithium peroxide may be subject to different regional subheadings depending on the specific national tariff schedule, though they converge at the 4-digit level.

FAQ

What is the HS code for lithium oxide?

The HS code for lithium oxide, as well as lithium hydroxide, is 2825.20.

Does the HS code change for lithium hydroxide monohydrate?

No, lithium hydroxide monohydrate is classified under the same HS code as the anhydrous form, 2825.20, because the presence of water of crystallization does not alter its chemical classification in Chapter 28.
