G-98, G-99 and G-99.5 grades from the Ragedara mine, Sri Lanka. Ultra-high natural crystallinity, zero acid purification, fully traceable — entirely outside China's export licensing regime.
The graphite industry distinguishes between flake, amorphous and vein graphite — but only vein graphite, sourced exclusively from Sri Lanka, achieves high natural carbon purity without chemical treatment.
Chinese and African flake graphite requires acid purification — typically hydrofluoric acid or alkaline roasting — to reach battery-grade purity levels of ≥98% Cg. Ceylon vein graphite from the Ragedara mine reaches these levels naturally, through geology alone. This matters for battery manufacturers in three ways: lower metallic impurity profile, simpler supply chain documentation, and a cleaner ESG footprint.
High crystallinity also translates directly to electrochemical performance. The ordered layered structure of vein graphite provides superior lithium-ion intercalation pathways, contributing to higher reversible capacity and stable cycling behaviour in Li-ion anodes.

| Grade | Carbon (Cg) | Typical application | Particle size (D50) | Ash content |
|---|---|---|---|---|
| G-98 | ≥98.0% Cg | Li-ion anode precursor, composite anode blends | 10–25 µm (custom) | <1.5% |
| G-99 | ≥99.0% Cg | Battery anode active material, advanced composites | 5–20 µm (custom) | <0.8% |
| G-99.5 | ≥99.5% Cg | High-performance anodes, graphene precursor, nuclear | 3–15 µm (custom) | <0.3% |
All values based on independent third-party laboratory analysis. Certificate of Analysis provided with every shipment. Custom particle sizing available — contact us with your D50, D90 and BET surface area specifications.
| Factor | Ceylon Vein (Ragedara) | Chinese Flake (processed) |
|---|---|---|
| Natural purity | 90–99.5% Cg — no treatment | 70–85% Cg raw; acid purification to reach ≥98% |
| Purification process | None required for battery grades | HF acid or high-temp alkaline — chemical waste stream |
| China export licence | Not applicable — Sri Lanka origin | Required since October 2023 — subject to quota |
| EU CRM Act risk | Fully diversified source country | Concentration risk — China controls ~80% of supply |
| Traceability | Single mine, 18th-century history, full CoA | Multiple mines, variable documentation |
| ESG / carbon footprint | Underground mining, no chemical processing | Open-pit + chemical flotation + acid purification |
| REACH documentation | Full documentation provided | Variable — supplier-dependent |
The EU Battery Regulation (2023/1542) introduces mandatory due diligence and carbon footprint requirements for battery materials including graphite. Ceylon vein graphite from the Ragedara mine — single origin, underground mined, no chemical processing — is positioned to meet these traceability requirements. Read our EU CRM Act overview →
