Importers of Bituminous Mixtures Based on Natural Asphalt, Bitumen, Petroleum Bitumen, Mineral Tar, or Pitch paid $17K in duties in April 2026 — an effective duty rate of 10% on $172K in dutiable value, based on actual customs collections rather than the published tariff schedule. Bituminous Mixtures Based on Natural Asphalt, Bitumen, Petroleum Bitumen, Mineral Tar, or Pitch imports of $8.2M in April 2026 ran 49% above the year-to-date monthly average of $5.5M.
Last updated: April 2026 dataReady-mixed bituminous compounds — including mastic asphalt, cut-back bitumen, and bitumen-based waterproofing compounds — are classified here when they are formulated mixtures rather than pure bituminous substances, placing them at the downstream end of the bitumen value chain. The heading's scope covers mixtures based on natural asphalt, petroleum bitumen, mineral tar, or pitch, and the mixture character (rather than any single component) governs classification. Canada and Colombia are the leading US import sources, with Belgium also supplying, reflecting both geographic proximity and European specialty formulation capacity. All trade enters under the single line 2715000000.

Heading 271500 covers products such as mastic asphalt (bitumen mixed with mineral filler), cut-back bitumen (bitumen dissolved in petroleum solvent), bitumen emulsions, and bituminous waterproofing compounds. The key distinction from pure petroleum bitumen (271320) is that these are deliberate formulations combining bitumen with other substances to achieve specific application properties — they are not the bituminous substance itself but a prepared mixture based on it.
Bituminous mixtures of Canadian origin may qualify for USMCA preferential tariff treatment, provided the goods meet the applicable rules of origin — typically a tariff classification change or regional value content requirement. Importers should obtain a USMCA certificate or certification of origin from the Canadian supplier and verify that the specific formulation satisfies the relevant origin rule before claiming the preference at entry.
