Tarred macadam — crushed stone or aggregate bound with tar rather than bitumen or slag — occupies a narrow classification niche under a single tariff line (2517300000), set apart from both slag macadam (251720) and asphalt-based road materials classified elsewhere. Its primary use is in road surfacing and pavement repair applications where tar-based binders are specified. Canada and the United Kingdom are the recorded US import sources, reflecting the product's stronger commercial presence in markets with older road-construction traditions. Importers should verify binder composition, as bitumen-bound materials may classify differently.

Tarred macadam uses tar as the binding agent, whereas bituminous road mixtures use bitumen or asphalt. This distinction is material to classification — bitumen-based road mixes fall under different headings, so the binder type must be confirmed in product documentation.
Canada and the United Kingdom are the recorded suppliers of tarred macadam to the US. The product's limited trade volume reflects its specialized application and the dominance of bituminous alternatives in modern road construction.
