Lithium carbonate (battery grade) sourcing guide
Battery-grade lithium carbonate requires purity above 99.5% with low sodium, iron and magnetic impurities; cathode makers usually run a lengthy sample qualification. Prices are volatile, so index-linked long-term contracts (e.g. Fastmarkets, SMM) are common.

Overview
Battery-grade lithium carbonate requires purity above 99.5% with low sodium, iron and magnetic impurities; cathode makers usually run a lengthy sample qualification. Prices are volatile, so index-linked long-term contracts (e.g. Fastmarkets, SMM) are common.
Typical applications
- LFP and NMC cathode materials
- lithium-ion cell production
- ceramics and glass
- lubricating greases
- pharmaceuticals
Specifications to agree with your supplier
When buying Lithium carbonate, agree in writing on the grade, applicable standard, packaging, delivery term (Incoterm) and acceptance criteria. Ask for a certificate of analysis (COA) for every lot, the technical data sheet (TDS) and, where relevant, the safety data sheet (SDS).
How to source reliably
Work with verified (KYC) suppliers, request samples and a trial lot before large volumes, use independent inspection (SGS, Bureau Veritas, etc.) and tie payment terms to shipping milestones. The platform deal room keeps offer history, the digital contract and delivery steps on record in one place.
Transport, storage & customs
Customs usually classify Lithium carbonate under HS heading 2836.91; always confirm the exact code in your importing country’s tariff. Store the goods dry, protected from moisture and direct sunlight with packaging intact, and ask for loading photos and the bill of lading (B/L) before shipment.
