U.S. imports of bitumen, natural asphalt, asphaltites & asphaltic rocks (HS 271490) totaled $7.4M in July 2026, traded with 6 countries.
Bitumen, Natural Asphalt, Asphaltites & Asphaltic Rocks imports of $7.4M in July 2026 ran 146% above the year-to-date monthly average of $3.0M.
Last updated: July 2026 dataNatural asphalt, asphaltites such as gilsonite, and asphaltic rocks are geologically occurring bituminous materials distinct from petroleum-derived bitumen, and their classification under 271490 rather than 271320 turns on whether the bituminous content is naturally deposited rather than a refinery product. Gilsonite in particular commands premium pricing as a specialty additive in drilling fluids, ink, and asphalt modification. Colombia leads US import supply under this heading, with Greece and Argentina also significant — a supplier mix that reflects deposits of natural lake asphalt (Trinidad-type) and European asphaltite sources. All trade enters under the single line 2714900000.

Gilsonite (uintaite) is a naturally occurring solid hydrocarbon asphaltite mined primarily in Utah and imported in smaller quantities. Unlike lake asphalt or asphaltic rock, gilsonite is nearly pure bitumen with very low mineral content, giving it unique solubility and binding properties valued in oil-well cement, printing inks, and asphalt modification. Its high purity distinguishes it from asphaltic rocks, which contain significant mineral matrix material.
A geological origin certificate or supplier declaration confirming the material is mined from a natural deposit — rather than produced as a refinery residue — is the primary supporting document. Laboratory analysis showing the absence of refinery processing markers (such as specific aromatic compound profiles) can further support the classification. CBP may request this documentation during examination, particularly for materials like natural lake asphalt that visually resemble petroleum bitumen.
