Raw graphite price

When sourcing raw graphite, the primary quality indicators are Fixed Carbon (FC) content, particle size distribution (mesh), and impurity levels. For industrial applications, you should prioritize suppliers offering 90% to 99% carbon purity. Flake graphite is categorized by size; Large Flake (+80 mesh) is highly valued for refractories, while Fine Flake (-100 mesh) is often used for lubricants or battery anodes. Always request a Certificate of Analysis (COA) to verify the levels of ash, moisture, and volatile matter.

For battery-grade applications, the graphite must be capable of being processed into spherical graphite, requiring high purity and specific crystalline structures. Industrial-grade graphite used in steelmaking or refractories focuses more on thermal shock resistance and oxidation resistance. Ensure the supplier can provide Scanning Electron Microscopy (SEM) images to confirm the morphology and X-ray Diffraction (XRD) data to verify the degree of graphitization.

Graphite mining and processing are subject to strict environmental regulations. Ensure your supplier complies with ISO 14001 (Environmental Management) and ISO 9001 (Quality Management). For international trade, verify that the product meets REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) standards if exporting to the EU, and check for Material Safety Data Sheets (MSDS) to ensure safe handling and transport of carbon-based powders.

Raw graphite is typically traded as Amorphous, Flake, or Vein graphite. Flake graphite generally commands a higher price due to its superior conductivity and flexibility. Amorphous graphite is more economical and suitable for lower-end applications like brake linings or foundry facings. The price is highly sensitive to mesh size; larger flakes are rarer and thus more expensive. Buyers should align the specific physical form with their end-product requirements to optimize cost-efficiency.

The most significant risks include quality inconsistency between samples and bulk orders, and fluctuations in international freight costs. Because graphite is a heavy bulk commodity, shipping delays can severely impact supply chains. To mitigate this, use third-party inspection services (like SGS or Intertek) to conduct pre-shipment testing at the loading port. Additionally, be aware of export duties or quotas that some resource-rich countries may impose on raw minerals.

Graphite prices are often indexed to market benchmarks. Negotiate based on volume-tiered pricing, where discounts of 5-10% are common for orders exceeding 20 tons. For payment, utilize Letter of Credit (L/C) or Trade Assurance to protect your funds until the Bill of Lading is issued. On platforms like Made-in-China.com, look for 'Audited Suppliers' to ensure you are dealing with legitimate factories rather than unlicensed brokers.

Raw graphite is often shipped in Jumbo Bags (1 ton each) or 25kg multi-wall paper bags on pallets. Ensure the packaging is moisture-proof to prevent clumping. For large volumes, FOB (Free On Board) is recommended as it allows the buyer to control the ocean freight and choose a reliable forwarder. Always clarify the Incoterms clearly in the contract to define where the risk transfers from the seller to the buyer.
