Products classified under Tariff item 2713.12.00
Calcined Delayed Coke
Calcined delayed coke is a high-carbon product obtained by subjecting green delayed coke to thermal treatment at temperatures above 1,200°C, removing volatile matter and moisture. It is used primarily in the aluminum and steel industries as a carbon source. This product falls under tariff item 2713.12.00 as calcined petroleum coke, a residue of petroleum oils.
Calcined Petroleum Coke
Calcined petroleum coke is produced by heating green petroleum coke to over 1,200°C, driving off volatile matter and increasing carbon purity. It is a key raw material for anodes in aluminum smelting and for other metallurgical applications. This product is classified under tariff item 2713.12.00 as calcined petroleum coke, a residue of petroleum refining.
Calcined Petroleum Needle Coke
Calcined petroleum needle coke is a premium grade of calcined coke with a distinctive needle-like crystalline structure, produced from specific feedstocks and calcination processes. It is primarily used in the manufacture of graphite electrodes for electric arc furnaces in steelmaking. Despite its specialized morphology, it remains a calcined petroleum coke residue and is classified under tariff item 2713.12.00.
Fluid Calcined Petroleum Coke
Fluid calcined petroleum coke is produced from the fluid coking process, resulting in a sponge-like structure with high porosity, suitable for metallurgical applications. It undergoes calcination to remove volatile matter and enhance carbon content. This product is classified under tariff item 2713.12.00 as calcined petroleum coke, a residue of petroleum oils.
Fuel-Grade Calcined Petroleum Coke
Fuel-grade calcined petroleum coke is a thermally treated petroleum coke with higher sulfur content, used as a fuel in power generation and cement kilns. Although its application is for fuel, it is still a calcined petroleum coke residue from petroleum refining. It is classified under tariff item 2713.12.00 as calcined petroleum coke.
Green Petroleum Coke Calcined Anode Grade
Green petroleum coke calcined anode grade is a high-quality calcined coke specifically processed for use in aluminum smelter anodes, with low ash and metal content. It is produced by calcining green coke to achieve high carbon purity and electrical conductivity. This product is classified under tariff item 2713.12.00 as calcined petroleum coke.
Isotropic Calcined Petroleum Coke
Isotropic calcined petroleum coke is a specialty calcined coke with uniform properties in all directions, used in applications like nuclear graphite and specialty carbon products. It is produced through controlled calcination of selected feedstocks. Despite its specialized nature, it is a calcined petroleum coke residue and is classified under tariff item 2713.12.00.
