carbon scrap price Manufacturers

When sourcing carbon scrap, the primary focus should be on Fixed Carbon content, which should ideally be 98% to 99% for high-quality applications. Buyers must verify the Sulphur content (typically <0.05% for premium grades) and Ash content (<0.5%) to ensure it doesn't contaminate the smelting process. Additionally, specify the particle size distribution (e.g., 0-10mm, 10-50mm) required for your specific furnace type to ensure optimal thermal conductivity and dissolution rates.

For buyers looking for electrode scrap, the Bulk Density (usually >1.55g/cm³) and Specific Resistance are critical. Ensure the material is sourced from Graphite Electrode ends or broken pieces rather than amorphous carbon if high electrical conductivity is required. It is essential to request a Chemical Analysis Report that details the levels of Nitrogen and Hydrogen, as low gas content is vital for high-quality steel production and foundry casting.

Suppliers should provide SGS or Intertek third-party inspection reports to validate the chemical composition. Ensure the product complies with ISO 9001 quality management systems. For international trade, verify that the material is classified correctly under HS Code 3801 (Artificial Graphite) or 8545 (Carbon Electrodes) to avoid customs delays. Always request a Material Safety Data Sheet (MSDS) to understand handling and storage requirements.

To maximize value, buyers should analyze the Price per Carbon Unit rather than just the gross weight. Purchasing in bulk (FCL - Full Container Loads) typically reduces the unit price by 10-15%. Consider sourcing from suppliers on Made-in-China.com who offer customized screening and crushing services, which can reduce your on-site processing costs. Additionally, evaluate the moisture content; high moisture increases weight and shipping costs without adding value.

The most significant risk is quality inconsistency, where the top layer of a shipment meets specs but the bottom contains high-ash impurities. To mitigate this, use Trade Assurance services and mandate a Pre-shipment Inspection (PSI). Another risk is price volatility in the needle coke and graphite markets; it is recommended to sign short-term fixed-price contracts or use formula-based pricing linked to market indices.

Focus negotiations on payment terms and purity guarantees. Request a staged payment plan (e.g., 30% deposit, 70% against BL copy and inspection report). Negotiate a penalty clause for moisture or impurity deviations exceeding the agreed-upon percentage. For long-term partnerships, ask for exclusive 'Gold Member' pricing available to verified buyers on professional platforms like Made-in-China.com.

Carbon scrap is often shipped in Jumbo Bags (1MT each) or in bulk within 20ft containers. Ensure the supplier uses moisture-proof packaging to prevent oxidation and weight gain during sea transit. For shipping to regions with strict environmental laws, confirm that the packaging is recyclable and that the vessel provides a Clean Bill of Lading to facilitate smooth customs clearance.

Always verify the supplier's Business License and Export Permit. Prioritize Audited Suppliers on Made-in-China.com, as they have undergone on-site verification of their production capacity and financial standing. Avoid making payments to third-party personal accounts; all transactions should be conducted through official corporate bank accounts or secure platform payment gateways.
