Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing lithium oxide or hydroxide impurities
Mixtures with significant lithium oxide/hydroxide shift to HTS 2825 per Chapter 28 notes excluding carbonates from other subchapter compounds.
If non-USP grade or industrial purity
Lower purity lithium carbonates fall under the general 'other' subheading 2836.92, not USP-specific 2836.91.0010.
If blended with organic stabilizers for retail pharma kits
Additives or preparations for retail sale reclassify as chemical preparations under 3824, per Chapter 28 exclusion note (h).

Import Tips & Compliance
• Verify USP certificate of analysis from supplier to confirm compliance with pharmacopeia standards
• Include detailed purity documentation (e.g
• >99.5% Li2CO3) to avoid reclassification
• Watch for moisture content labels as it affects stability during shipping
