HS Code for Calcined petroleum coke

Calcined petroleum coke is classified under HS code 271312, which specifically covers "Petroleum coke; calcined, obtained from bituminous minerals." This classification is precise, distinguishing petroleum coke that has undergone a high-temperature thermal treatment process (calcination) from its uncalcined counterpart. Calcination removes moisture, volatile matter, and impurities, significantly increasing the material's carbon content, density, and electrical conductivity. This process is crucial for transforming green petroleum coke into a high-quality carbon material suitable for specialized industrial applications, particularly as an anode material in aluminum smelting and in the production of graphite electrodes. The code emphasizes both the origin (petroleum coke) and the specific processing step (calcination).

Products Included

• Calcined petroleum coke (CPC) in various particle sizes
• Anode-grade calcined petroleum coke
• Graphite-grade calcined petroleum coke
• Electrode-grade calcined petroleum coke
• Petroleum coke that has undergone thermal treatment above 1200°C

Common Misclassification

The most frequent misclassification for calcined petroleum coke is with uncalcined petroleum coke, which falls under HS code 271311, covering "Petroleum coke; not calcined." The critical distinction is the calcination process itself. Green petroleum coke (271311) is the raw material directly from the coker unit, containing higher levels of volatile matter and moisture, whereas calcined petroleum coke (271312) has been heat-treated to remove these impurities, making it suitable for higher-value applications. Incorrectly identifying the processing state can lead to significant customs discrepancies. Another potential area of confusion is with HS code 270400, which covers "Coke and semi-coke of coal, of lignite or of peat." This code is for coke derived from coal or other solid fossil fuels, not petroleum, and therefore is distinct from petroleum coke. Furthermore, highly processed carbon materials like artificial graphite (380110) are distinct from calcined petroleum coke, as they represent a further stage of manufacturing beyond simple calcination.

FAQ

What is the HS code for Calcined petroleum coke?

The HS code for Calcined petroleum coke is 271312. This code specifically designates petroleum coke that has undergone a calcination process, distinguishing it from uncalcined forms due to its enhanced properties for industrial use.

What is the primary difference between HS 271311 and 271312?

The primary difference is the calcination process. HS 271311 covers uncalcined (green) petroleum coke, which is the raw material. HS 271312 covers petroleum coke that has been calcined, meaning it has undergone high-temperature thermal treatment to remove impurities and enhance its carbon content and conductivity.
