Product classification
HS code for Green petroleum coke: 2713.11
Petroleum coke, (not calcined), obtained from bituminous minerals.
Classification of green petroleum coke under HS 2713.11
Green petroleum coke is classified under HS code 2713.11, which is the specific designation for petroleum coke that has not been calcined. This material is a byproduct of the oil refining process, specifically from the thermal cracking of heavy residual oils in a coker unit. The term "green" is a technical industry descriptor indicating that the coke is in its raw form, containing a significant percentage of volatile matter, typically ranging from 8% to 15%. Under the Harmonized System, Chapter 27 covers mineral fuels and mineral oils. Heading 2713 is dedicated to petroleum coke, petroleum bitumen, and other residues of petroleum oils. The classification under 2713.11 is determined by the absence of the calcination process, which is a secondary heat treatment used to remove volatile hydrocarbons and increase the carbon purity of the coke. Customs authorities rely on laboratory analysis of the volatile matter and moisture content to verify that the product has not been calcined, as calcined petroleum coke is classified separately under 2713.12. This distinction is vital because green coke is often used as a fuel or as a feedstock for calcining, whereas calcined coke is primarily used in the production of anodes for aluminum smelting. The classification is governed by GRI 1, as the subheading text for 2713.11 explicitly provides for the non-calcined state.

Codes often confused with 2713.11
Common mistake. The most common misclassification occurs with calcined petroleum coke, which is classified under HS code 2713.12. Importers often fail to distinguish between the two, despite the significant difference in value and industrial application. Another error involves classifying green coke as bituminous coal under 2701.12. While both are carbonaceous fuels, petroleum coke is a residue of oil refining, whereas coal is a naturally occurring mineral, placing them in entirely different headings within Chapter 27.
Top exporters and importers of HS 271311 (the code used for green petroleum coke), 2025
In 2025, the largest exporter of HS 271311 (the code used for green petroleum coke) in UN Comtrade data was the United States, with 50% of world exports; the largest importer in UN Comtrade data was China, with 35% of world imports.

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).
