HS Code 27.13 – Petroleum coke, petroleum bitumen; other residues of petroleum oils or oils obtained from bituminous minerals
What HS 27.13 covers
Heading 2713 covers petroleum coke, petroleum bitumen, and other heavy residues derived from petroleum oils or oils obtained from bituminous minerals. This classification specifically encompasses the final, heaviest by-products remaining after the extensive distillation and cracking processes of crude petroleum in refineries. Key products include various grades of petroleum coke (calcined, green, fuel-grade) and different types of petroleum bitumen (paving, industrial, oxidized). It's crucial to distinguish these products from naturally occurring bitumen (covered under 2714) and from prepared bituminous mixtures that incorporate aggregates or other substances (classified under 2715). This heading is vital for trade compliance due to the significant volume and specific quality requirements of these bulk commodities. Accurate classification impacts duties, adherence to environmental regulations (especially for fuel-grade coke), and quality specifications for industries such as aluminum smelting (for anode-grade coke), steel manufacturing (as a carbon source), power generation (as a low-cost fuel), and road construction (using bitumen). Historically, these residues have been essential for heavy industry and infrastructure development, with their trade volumes reflecting global industrial activity and energy demands. As direct derivatives of petroleum refining, these products are perfectly aligned with Chapter 27, which focuses on mineral fuels and products of their distillation.

- Examples
An aluminum smelter in Iceland regularly imports large quantities of calcined petroleum coke from the United States, utilizing bulk carriers to transport this essential raw material for the production of carbon anodes. A major road construction firm in India sources bulk paving grade petroleum bitumen from the United Arab Emirates, shipped via tankers, to produce asphalt mixes for extensive infrastructure projects across the subcontinent. A power generation facility in Japan imports fuel-grade petroleum coke from Venezuela as a cost-effective energy source, typically via long-haul ocean freight. A roofing material manufacturer in Mexico procures oxidized bitumen from refineries in Texas, USA, for producing asphalt shingles and waterproofing membranes, transported by rail and truck across the border.

Codes often confused with 27.13
Common mistake. Misclassifications under HS 2713 frequently occur due to the subtle distinctions between raw residues and processed products or natural counterparts. A common mistake is confusing petroleum bitumen with natural bitumen and asphalt, which fall under 2714. The key differentiator is the origin: 2713 is strictly petroleum-derived from refinery processes, while 2714 covers naturally occurring deposits. Another frequent error is classifying prepared bituminous mixtures, such as asphalt concrete for roads, under 2713; these finished products, which include aggregates and other components, belong in 2715. Lastly, while these are residues of petroleum oils, classifying them as crude petroleum oils (2709) or lighter refined fuel oils (2710) is incorrect, as 2713 specifically covers the heavy, non-distillable residues.
Top exporters and importers of HS code 2713, 2025
In 2025, the largest exporter of HS code 2713 in UN Comtrade data was the United States, with 20% of world exports; the largest importer in UN Comtrade data was China, with 18% 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).
