HS code for Marble powder: 2517.41
Stones, of marble, in granules, chippings and powder, whether or not heat-treated.
Classification of marble powder under HS 2517.41
Marble powder is classified under HS code 2517.41. This classification is part of the broader category for stones in granules, chippings, and powder. The Harmonized System distinguishes between the type of stone and its physical state. For marble, the powder form resulting from the mechanical crushing or grinding of marble rock is specifically directed to 2517.41. This code is used regardless of whether the powder is used for industrial fillers, agricultural applications, or construction materials like terrazzo. It is important to note that the classification remains in Chapter 25 as long as the powder is natural marble that has been mechanically processed. The classification is governed by the material's mineralogical identity as marble and its physical form as a powder. If the powder is extremely fine (micronized), it still remains under this code unless it has been chemically altered. The consistency of the powder, ranging from coarse flour to fine dust, does not change the primary classification under 2517.41, provided no chemical additives or binders have been introduced to the material.

Codes often confused with 2517.41
Common mistake. A frequent misclassification occurs with HS code 2836.50, which is for calcium carbonate. While marble is chemically calcium carbonate, 2836.50 is reserved for the chemically pure or precipitated version. Natural marble powder must stay in 2517.41. Additionally, it is sometimes confused with 2517.49, which is the residual category for granules and powder of other stones (like granite or porphyry) that are not marble.

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).
