Product classification
HS code for Coke: 2704.00
Coke and semi-coke, of coal, lignite or peat, whether or not agglomerated, retort carbon.
Classification of coke under HS 2704.00
HS code 2704.00 covers coke and semi-coke derived from coal, lignite, or peat. This classification is part of Chapter 27, which encompasses mineral fuels, mineral oils, and products of their distillation. Coke is a solid carbonaceous residue derived from the destructive distillation of low-ash, low-sulfur bituminous coal. The process, known as coking, involves heating the coal in the absence of air to remove volatile constituents like water, coal gas, and coal tar. The resulting product is used primarily in industrial processes, such as smelting iron ore in blast furnaces, due to its high carbon content and physical strength. The HS code 2704.00 is a "single-dash" heading that does not further subdivide at the international level, meaning it covers all forms of coke and semi-coke regardless of their specific industrial application, provided they are derived from the specified mineral sources. This also includes retort carbon, which is a hard, black form of carbon that deposits on the walls of retorts used for the distillation of coal. Proper classification is vital because coke is a critical industrial input and often subject to specific trade quotas or environmental levies.

Codes often confused with 2704.00
Common mistake. The most frequent misclassification occurs with petroleum coke, which is classified under 2713.11 or 2713.12. While both are called "coke," petroleum coke is a byproduct of oil refining, whereas 2704.00 is strictly for coal, lignite, or peat derivatives. Additionally, raw coal is classified under 2701, and artificial graphite is classified under 3801. Distinguishing between these is essential as the carbon content and manufacturing process differ significantly.
Top exporters and importers of HS 270400 (the code used for coke), 2025
In 2025, the largest exporter of HS 270400 (the code used for coke) in UN Comtrade data was Poland, with 24% of world exports; the largest importer in UN Comtrade data was India, with 14% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 270400, not only coke.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. 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).
