Product classification
HS code for Petroleum coke: 2713.11
Petroleum coke, (not calcined), obtained from bituminous minerals.
Classification of petroleum coke under HS 2713.11
Petroleum coke, specifically the non-calcined variety, is classified under HS code 2713.11. This classification is determined by the product's origin as a byproduct of the oil refining process, specifically from the coking unit where heavy residual oils are thermally cracked. Under Chapter 27, which covers mineral fuels and oils, heading 2713 is dedicated to petroleum coke, petroleum bitumen, and other residues of petroleum oils. The subheading 2713.11 is reserved for coke that has not undergone the calcination process. Calcination involves heating the green coke to high temperatures to remove volatile matter and increase carbon density. Therefore, raw or \"green\" petroleum coke, which still contains a significant amount of moisture and volatile hydrocarbons, must be placed here. The classification relies on the physical state and the degree of processing. If the coke is obtained from bituminous minerals and remains in its raw, porous, and relatively soft state compared to its calcined counterpart, it fits the criteria for 2713.11. This material is primarily used as a fuel source in cement kilns and power plants due to its high calorific value, or as a feedstock for the calcining process itself.

Codes often confused with 2713.11
Common mistake. The most frequent error is confusing 2713.11 with 2713.12, which is the code for calcined petroleum coke. The distinction lies in the heat treatment; calcined coke has been processed at temperatures above 1000 degrees Celsius to remove impurities. Another common error is misclassifying it under 2704.00, which covers coke and semi-coke of coal, lignite, or peat. While they look similar, petroleum coke is a residue of oil refining, whereas coal coke is derived from coal carbonization.
Top exporters and importers of HS 271311 (the code used for petroleum coke), 2025
In 2025, the largest exporter of HS 271311 (the code used for 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. 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 petroleum coke
What is the HS code for Petroleum coke?
The HS code for Petroleum coke is 271311 (Petroleum coke; (not calcined), obtained from bituminous minerals). The HS code for non-calcined petroleum coke is 2713.11, while calcined petroleum coke is 2713.12.
How do I classify Petroleum coke for customs?
Petroleum coke is classified under HS code 271311 — Petroleum coke; (not calcined), obtained from bituminous minerals. This is a 6-digit subheading level code.
How do I distinguish between green and calcined coke for customs?
Green coke (2713.11) has a higher volatile matter content (usually 8% to 15%) and lower density, whereas calcined coke (2713.12) has been heat-treated to reduce volatiles to less than 1%.
Which countries are the top exporters of petroleum coke (HS 271311)?
