Stone, natural (excluding marble, travertine, alabaster, other calcareous stone or granite), monumental or building stone, (other than simply cut or sawn, with a flat or even surface).
Classification of building stone products under HS 6802.99
Building stone products are classified under HS code 6802.99 when they consist of natural stone that has been worked beyond the stage of simple squaring or sawing. This code is found in Chapter 68, which covers articles of stone and other mineral materials. Heading 6802 specifically deals with worked monumental or building stone. The system divides these products by the type of stone: marble, travertine, and alabaster (6802.21/6802.91), calcareous stone (6802.22/6802.92), and granite (6802.23/6802.93). Subheading 6802.99 is the residual category for "other" stones, such as sandstone, basalt, porphyry, or quartzite, that have been polished, carved, or otherwise further worked. To be classified here, the stone must not have a simple flat or even surface (which would fall under 6802.29); instead, it usually features decorative work, molding, or complex shaping.

Codes often confused with 6802.99
Common mistake. The most common misclassification is using 6802.29, which is for "other" stones that are simply cut or sawn with a flat surface. If the stone is polished or carved, it must move to 6802.99. Another error is confusing these with raw stone from Chapter 25 (e.g., 2515 or 2516), which only covers stone that is roughly trimmed or merely cut into blocks without further processing.

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).
