HS Code 2516.90 – Monumental or building stone; n.e.c. in heading no. 2516, whether or not roughly trimmed or merely cut, by sawing or otherwise, into blocks or slabs of a rectangular (including square) shape
HS code 2516.90 is the 6-digit subheading for monumental or building stone, n.e.c. in heading no. 2516, whether or not roughly trimmed or merely cut, by sawing or otherwise, into blocks or slabs of a rectangular (including square) shape. It is used for porphyry blocks, basalt slabs, quartzite building stone, slate blocks (for building) and serpentine slabs.
What HS 2516.90 covers
This 'not elsewhere specified' (NES) code within heading 2516 covers various other monumental or building stones, such as porphyry, basalt, quartzite, or slate, in their raw (roughly trimmed) or initially cut (rectangular blocks/slabs) forms. These stones are selected for specific aesthetic, structural, or durability requirements in diverse applications, including high-traffic paving, specialized architectural features, and monumental works. Importers are often specialized construction companies, architects, and stone fabricators seeking unique or high-performance materials not covered by the more common granite, marble, or sandstone categories. Exporters are countries with diverse geological resources and the infrastructure to quarry and process these less common but equally valuable building stones, catering to niche markets and specialized architectural projects globally.

Common mistake. This code is a residual category for stones not covered by 2515 (marble, alabaster) or specific granite/sandstone codes (251611, 251612, 251620); it's crucial to ensure the stone isn't already classified elsewhere.

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).
