HS code for Graphite flakes: 2504.10
Graphite, natural, in powder or in flakes.
Classification of graphite flakes under HS 2504.10
Graphite flakes are classified under HS code 2504.10. This code is situated in Chapter 25, which covers salt, sulfur, earths, and stone, as well as plastering materials, lime, and cement. Heading 2504 is dedicated to natural graphite, a mineral substance composed of carbon. The subheading 2504.10 specifically applies to natural graphite that is presented in the form of powder or flakes. Flake graphite is a naturally occurring form of graphite that is found as isolated, flat, plate-like particles in metamorphic rocks. The classification depends on the graphite being "natural"—meaning it was extracted from the earth and has not undergone the high-temperature graphitization process used to create synthetic graphite. Processing steps such as crushing, grinding, and flotation to remove impurities are permitted under Chapter 25, provided they do not change the fundamental crystalline structure of the mineral.

Codes often confused with 2504.10
Common mistake. The most frequent misclassification is with HS code 3801.10, which is for artificial (synthetic) graphite. Artificial graphite is manufactured from petroleum coke or coal tar pitch and has different physical properties. Another error is using 2504.90, which is a residual category for natural graphite that is not in powder or flake form, such as large lumps or "run-of-mine" ore that has not been processed into flakes.
Top exporters and importers of HS 250410 (the code used for graphite flakes), 2025
In 2025, the largest exporter of HS 250410 (the code used for graphite flakes) in UN Comtrade data was China, with 43% of world exports; the largest importer in UN Comtrade data was the United States, with 24% 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 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).
