Quartzite, whether or not roughly trimmed or merely cut, by sawing or otherwise, into blocks or slabs of a rectangular (including square) shape.
Classification of quartzite slabs under HS 2506.20
Quartzite slabs are classified under HS code 2506.20. This heading is part of Chapter 25, which deals with mineral products in their crude or minimally processed states. Heading 2506 covers quartz (other than natural sands) and quartzite. While 2506.10 is used for quartz in its crude or bulk form, 2506.20 is specifically for quartzite, a metamorphic rock. The classification includes quartzite that is in its natural state or has been roughly trimmed. Crucially, it also includes quartzite that has been merely cut, by sawing or otherwise, into blocks or slabs of a rectangular or square shape. This classification is strictly for stone that has not yet been further worked. The slabs must not have been polished, chamfered, drilled, or otherwise processed into a finished product. The HS code 2506.20 represents the raw material stage of the stone before it enters the manufacturing process for countertops or flooring.

Codes often confused with 2506.20
Common mistake. Quartzite slabs are frequently misclassified under 6802.99. Heading 6802 is for worked monumental or building stone. If the quartzite slab has been polished, honed, or had its edges finished, it must be classified in Chapter 68. HS code 2506.20 is only for slabs that are "merely cut" and remain in a raw, unpolished state. Additionally, it should not be confused with 2506.10, which is for quartz (the mineral) rather than quartzite (the rock).

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).
