Product classification
HS code for Calcined petroleum coke: 2713.12
Petroleum coke, calcined, obtained from bituminous minerals.
Classification of calcined petroleum coke under HS 2713.12
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).

Codes often confused with 2713.12
Common mistake. 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.
Top exporters and importers of HS 271312 (the code used for calcined petroleum coke), 2025
In 2025, the largest exporter of HS 271312 (the code used for calcined petroleum coke) in UN Comtrade data was the United States, with 37% of world exports; the largest importer in UN Comtrade data was Australia, with 9.1% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about calcined petroleum coke
What is the HS code for Calcined petroleum coke?
The HS code for Calcined petroleum coke is 271312 (Petroleum coke; calcined, obtained from bituminous minerals). 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.
How do I classify Calcined petroleum coke for customs?
Calcined petroleum coke is classified under HS code 271312 — Petroleum coke; calcined, obtained from bituminous minerals. This is a 6-digit subheading level code.
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.
Which countries are the top exporters of calcined petroleum coke (HS 271312)?
In 2025, the top exporters of HS 271312 (the code used for calcined petroleum coke) in UN Comtrade data were the United States ($1.1B, 37% of world exports), China ($598M) and Oman ($276M). World exports came to about $2.8B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of calcined petroleum coke (HS 271312)?
