HS code for Travertine blocks: 2515.11
Marble and travertine, having a specific gravity of 2.5 or more, crude or roughly trimmed by sawing or otherwise, into blocks or slabs of a rectangular (including square) shape.
Classification of travertine blocks under HS 2515.11
Travertine blocks are classified under HS code 2515.11, which is situated within Chapter 25 of the Harmonized System. This chapter is generally reserved for mineral products in their crude, unworked, or minimally processed states. Heading 2515 specifically addresses marble, travertine, ecaussine, and other calcareous monumental or building stone with a specific gravity of 2.5 or more. The subheading 2515.11 is designated for stone that is either crude or roughly trimmed. "Crude" refers to the stone as it is extracted from the quarry, often in irregular shapes. "Roughly trimmed" indicates that the stone has been shaped, often by sawing, into blocks or slabs of a rectangular or square shape, but the surfaces remain rough and have not undergone any further finishing. This classification is critical because it distinguishes raw material from worked stone. The specific gravity requirement of 2.5 is a technical threshold; if the stone is less dense, it may fall under different headings such as 2516 for granite or 2515.20 for alabaster. The primary characteristic for 2515.11 is the lack of advanced processing; the surfaces must remain rough or only roughly squared to facilitate transport or further processing at a masonry yard.

Codes often confused with 2515.11
Common mistake. Travertine blocks are frequently confused with HS code 2515.12. The distinction lies in the degree of sawing; 2515.12 is for stone "merely cut" into slabs, which implies a cleaner, more precise cut than "roughly trimmed" under 2515.11. Another common error is classifying these under 6802.91. However, 6802 is for worked stone. If the block has been polished or further shaped for a specific architectural use, it must move to Chapter 68.
Top exporters and importers of HS 251511 (the code used for travertine blocks), 2025
In 2025, the largest exporter of HS 251511 (the code used for travertine blocks) in UN Comtrade data was Italy, with 57% of world exports; the largest importer in UN Comtrade data was Italy, 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).
