Petroleum Coke, Calcined

Calcined petroleum coke undergoes high-temperature treatment that drives off volatile matter and moisture, yielding a dense, electrically conductive carbon material that is the primary anode feedstock for primary aluminum smelting and a key input for titanium dioxide and steel electrode production. Classified under a single 10-digit line (2713120000), its quality is defined by sulfur content, real density, and crystalline structure rather than physical form. Brazil and Argentina lead US import supply, with Japan and South Africa also among the top sources — a supplier profile shaped by proximity to aluminum smelting capacity and calcining infrastructure. Buyers routinely specify sulfur thresholds below 3% for anode-grade material.
