Natural Bitumen
Natural bitumen is a naturally occurring viscous mixture of hydrocarbons found in oil sands and tar pits, classified under HTS 2714.90.00.00 as 'other' bitumen and asphalt, natural. It is extracted directly from geological deposits without refining and used primarily in road paving and waterproofing.
Natural Asphalt (Trinidad Lake Asphalt)
Trinidad Lake Asphalt is a naturally occurring asphalt lake deposit, pure and unrefined, under HTS 2714.90.00.00 as natural asphalt. It is shoveled directly from the lake and prized for high-quality road surfacing.
Asphaltites (Gilsonite)
Gilsonite, a type of asphaltite, is a natural shiny black solid hydrocarbon found in vein deposits, fitting HTS 2714.90.00.00 as asphaltic rocks. It is mined directly and used in inks, paints, and asphalt additives due to its high asphalt content.
Asphaltic Rock (Rock Asphalt)
Asphaltic rock, or rock asphalt, is natural limestone impregnated with bitumen, classified in HTS 2714.90.00.00 as asphaltic rocks. It is quarried and crushed for direct use in road bases and roofing without separation of the bitumen.
Bituminous Shale
Bituminous shale is a sedimentary rock containing solid bituminous material, covered under HTS 2714.90.00.00 as bituminous or oil shale. It is mined for energy or asphalt production and differs from oil shale by its higher solid bitumen content.
Tar Sands (Athabasca Bitumen Ore)
Tar sands, such as Athabasca-type, consist of sand grains coated with natural bitumen, classified under HTS 2714.90.00.00 as bituminous or oil shale and tar sands. They require mining and are used for bitumen recovery in heavy oil production.
