Product classification
HS code for Coal coke: 2704.00
Coke and semi-coke, of coal, lignite or peat, whether or not agglomerated, retort carbon.
Classification of coal coke under HS 2704.00
Coal coke is classified under HS code 2704.00, which covers coke and semi-coke of coal, lignite, or peat, whether or not agglomerated, as well as retort carbon. This classification falls within Chapter 27, which deals with mineral fuels, mineral oils, and products of their distillation. Coke is the solid carbonaceous residue derived from the destructive distillation of low-ash, low-sulfur bituminous coal. The process involves heating the coal to high temperatures (up to 1,100°C) in the absence of oxygen to remove volatile constituents such as water, coal gas, and coal tar. The resulting material is primarily carbon and is essential in industrial processes, particularly in the smelting of iron ore in blast furnaces, where it acts as both a fuel and a reducing agent. Semi-coke is produced at lower temperatures and contains more volatile matter than standard coke. The HS code 2704.00 is a 'single-dash' heading that does not have further international sub-divisions, meaning it encompasses all forms of coke regardless of their specific industrial application or the degree of agglomeration.

Codes often confused with 2704.00
Common mistake. Coal coke is frequently confused with raw coal, which is classified under heading 2701. The key difference is the processing; 2701 is for natural coal, while 2704.00 is for coal that has undergone carbonization. Another misclassification occurs with petroleum coke, which is a byproduct of oil refining and is classified under HS code 2713.11 or 2713.12. Additionally, artificial graphite is sometimes confused with retort carbon, but artificial graphite is classified under 3801.10. It is crucial to distinguish between these based on the source material (coal vs. petroleum) and the manufacturing process.
Top exporters and importers of HS 270400 (the code used for coal coke), 2025
In 2025, the largest exporter of HS 270400 (the code used for coal 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 coal 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).

Questions about coal coke
What is the HS code for Coal coke?
The HS code for Coal coke is 270400 (Coke and semi-coke; of coal, lignite or peat, whether or not agglomerated; retort carbon). The HS code for coke and semi-coke of coal is 2704.00.
How do I classify Coal coke for customs?
Coal coke is classified under HS code 270400 — Coke and semi-coke; of coal, lignite or peat, whether or not agglomerated; retort carbon. This is a 6-digit subheading level code.
Is petroleum coke included in this code?
No, petroleum coke is classified separately under heading 2713, as it is a residue of the petroleum refining process rather than coal distillation.
Which countries are the top exporters of coal coke (HS 270400)?
In 2025, the top exporters of HS 270400 (the code used for coal coke) in UN Comtrade data were Poland ($1.7B, 24% of world exports), Indonesia ($1.4B) and China ($1.3B). World exports came to about $7.1B, 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.
