Last updated: August 2026 dataCalcined petroleum coke is a critical industrial carbon material produced by thermally treating green coke to remove volatiles, yielding a dense, low-impurity product used almost exclusively as a carbon anode in primary aluminum smelting and as a recarburizer in steel production. The aluminum industry's demand for consistent sulfur and metal-impurity specifications makes grade certification a central procurement concern. Brazil leads US import supply under this heading, with Argentina and Japan also significant sources — a supplier profile that reflects both South American refining capacity and Japanese specialty carbon production. All trade enters under the single line 2713120000.

Anode-grade calcined coke must meet tight limits on sulfur, vanadium, nickel, and silicon content because impurities transfer directly into the aluminum melt during electrolysis, degrading metal purity and anode performance. Fuel-grade petcoke tolerates much higher sulfur levels. Importers supplying smelters typically provide a certificate of analysis for each lot, and contracts often include penalty clauses for specification deviations.
As of available information, calcined petroleum coke from Brazil is not subject to antidumping or countervailing duty orders in the US. However, trade-remedy status can change; importers should verify current CBP and Commerce Department records before finalizing sourcing decisions, particularly given Brazil's position as the leading supplier under this heading.
