2517.10.00—Pebbles, gravel, broken or crushed stone, of a kind commonly used for concrete aggregates, for road metalling, or for railway or other ballast, shingle and flint, whether or not heat-treated

HTS 2517.10.00 is an 8-digit tariff item of the U.S. Harmonized Tariff Schedule covering Pebbles, gravel, broken or crushed stone, of a kind commonly used for concrete aggregates, for road metalling, or for railway or other ballast, shingle and flint, whether or not heat-treated. It belongs to Chapter 25 and rolls up 3 10-digit statistical lines that brokers actually file at entry.

Every 10-digit line under HTS 2517.10.00 carries a general (Column 1) duty rate of Free. Section 301, Section 232, and AD/CVD overlays may stack on top of this rate at the per-line level — open a specific 10-digit code to see its complete tariff stack.

U.S. Customs requires entries to be filed at the 10-digit statistical level — the broader tariff item HTS 2517.10.00 is not directly fileable. Match your product description to the most specific 10-digit line in the list on this page; if multiple lines could apply, the General Rules of Interpretation (GRIs) and chapter notes determine which one governs.
