Quartzite imports of $1.6M in July 2026 ran 24% above the year-to-date monthly average of $1.3M.
Last updated: July 2026 dataA metamorphic rock formed from sandstone under heat and pressure, quartzite enters US trade in two forms: crude or roughly trimmed (2506200010) and further processed material (2506200080), with the processing state determining classification. Canada is the primary supplier, with Brazil, Italy, Vietnam, and India also contributing — a supplier mix that reflects both proximity and the global dimension stone and construction aggregate trades. Quartzite's hardness and weather resistance make it a preferred material for flooring, cladding, road base, and railroad ballast.

CBP guidance generally treats quartzite as 'crude or roughly trimmed' when it has been extracted and broken or split to manageable size without further shaping. Once it has been sawn, cut to specific dimensions, or surface-finished beyond rough trimming, it typically moves to the NESOI line (2506200080) — or potentially out of heading 2506 entirely into Chapter 68 if it constitutes worked stone.
Quartz (heading 2506.10) refers to the mineral in its crystalline or granular form, while quartzite (heading 2506.20) is a distinct rock type — a metamorphosed sandstone in which quartz grains have recrystallized into an interlocking mosaic. The structural character of the material, not just its silica content, determines which subheading applies.
