Bituminous Mixtures Based on Natural Asphalt, Natural Bitumen, Petroleum Bitumen, Mineral Tar, or Mineral Tar Pitch

Bituminous mixtures formulated from natural asphalt, natural bitumen, petroleum bitumen, or mineral tar pitch are widely used in road paving, waterproofing membranes, and industrial sealants — making this heading a key input for infrastructure and construction supply chains. The entire heading is captured in tariff line 2715000000, with no further US schedule subdivisions. Canada is the leading supplier, followed by Colombia and Belgium, with Serbia and India also present in the import mix. Importers should be aware that the binder composition of a mixture — whether petroleum-derived or naturally sourced — can affect both classification and any applicable trade-remedy exposure.
