Last updated: July 2026 dataGranules, chippings, and powders of stone other than marble — including granite, basalt, limestone, and similar crushed materials — serve the construction, roofing, and filtration industries and enter the US under tariff line 2517490000. Jamaica is the leading supplier to the US market, reflecting its significant basalt and limestone aggregate export capacity, with Canada and New Zealand also notable sources. Importers should pay close attention to the specific stone type declared, as certain processed stone powders may be reclassified into Chapter 68 if they have undergone significant working.

68 shipments/mo
Jamaica has extensive deposits of high-quality basalt and limestone that are well-suited for aggregate production. Its proximity to US East Coast and Gulf ports makes bulk shipment economically competitive, and the island's established quarrying infrastructure supports consistent export volumes.
The key distinction is the degree of processing: granules, chippings, and powders that are simply crushed or ground from natural stone remain in Chapter 25. Once stone is cut, shaped, or otherwise worked into articles (tiles, slabs, monuments), it moves to Chapter 68. The form of the product at the time of importation — loose aggregate versus a shaped article — is the determining factor.
