Last updated: April 2026 dataBrazil leads US imports under this residual worked-stone heading, which captures quartzite, sandstone, and other non-calcareous, non-granite stones that have been worked beyond simple sawing. The US schedule carves out dedicated lines for stone monuments, bases, and markers (6802990030), quartzite slabs (6802990050), other quartzite (6802990070), and a catch-all (6802990090), reflecting the commercial significance of quartzite as a countertop and paving material. Correct classification within the heading turns on both stone type and product form, making accurate mineralogical identification on commercial invoices important for avoiding reclassification.

No. Engineered quartz countertop material — composed of crushed quartz bound with resin — is an agglomerated stone product and classifies under HTS heading 6810 (articles of cement, concrete, or artificial stone) rather than under 6802, which covers natural stone articles. Only natural quartzite and other natural stone articles fall within 6802.99.
The slab line covers quartzite articles in slab form — flat, relatively thin pieces used for countertops or cladding — while the other quartzite line captures quartzite articles in other forms such as paving sets, tiles, or shaped architectural pieces. The product's physical form and intended application guide the distinction.
