HS Code for Lithium carbonate

Lithium carbonate is classified under HS code 2836.91. This classification is determined by the General Rules for the Interpretation (GRI) of the Harmonized System, specifically GRI 1, which states that classification is governed by the terms of the headings and any relative section or chapter notes. Lithium carbonate is a separate chemically defined inorganic compound. Chapter 28 covers inorganic chemicals, and heading 2836 is designated for carbonates and peroxocarbonates. Within this heading, subheading 2836.91 is specifically reserved for lithium carbonate. This classification applies to the substance regardless of its purity level, encompassing both technical grade used in ceramics and high-purity battery grade used in the manufacturing of lithium-ion battery cathodes. The chemical formula Li2CO3 defines its placement here, provided it has not been mixed with other ingredients to form a preparation or put up in measured doses for medical use.

Products Included

• Technical grade lithium carbonate (99% purity)
• Battery grade lithium carbonate (99.5% or higher purity)
• Pharmaceutical grade lithium carbonate in bulk form
• Lithium carbonate powder for industrial glass manufacturing
• Lithium carbonate used as a flux in ceramic glazes

Common Misclassification

Lithium carbonate is frequently confused with HS code 2825.20, which covers lithium oxide and hydroxide. While both are primary lithium chemicals, the carbonate structure (CO3) necessitates classification under 2836. Another common error involves pharmaceutical-grade lithium carbonate. If it is put up in measured doses, such as tablets or capsules for the treatment of bipolar disorder, it must be classified under heading 3004 as a medicament. However, bulk lithium carbonate intended for pharmaceutical manufacturing remains in 2836.91. Additionally, mixtures containing lithium carbonate for specific metallurgical uses may be classified in Chapter 38 if they no longer meet the definition of a separate chemically defined compound.

FAQ

What is the HS code for lithium carbonate?

The international HS code for lithium carbonate is 2836.91.

Is battery-grade lithium carbonate classified differently than industrial grade?

No, both battery-grade and industrial-grade lithium carbonate are classified under HS code 2836.91, as the HS system generally does not distinguish between different purity levels for this specific chemical compound.
