Products classified under Tariff item 2714.90
Asphaltic Rock (Rock Asphalt)
Asphaltic rock, also known as rock asphalt, is natural limestone or sandstone impregnated with bitumen. It is quarried and crushed for direct use in road bases, paving, and roofing applications without separation of the bitumen from the mineral matter.
2714.90.00Asphaltites (Gilsonite)
Gilsonite, a type of asphaltite, is a natural, shiny, black solid hydrocarbon found in vein deposits. It is mined directly and used in inks, paints, varnishes, and as an asphalt additive due to its high softening point and solubility.
2714.90.00Bituminous Shale
Bituminous shale is a sedimentary rock containing solid bituminous material, distinct from oil shale by its higher bitumen content. It is mined for energy production or asphalt manufacturing and falls under the tariff item covering bituminous or oil shale.
2714.90.00Dennilite Asphaltite
Dennilite is a rare asphaltite mineral, a natural solid hydrocarbon occurring in specific vein formations. It is used in specialty asphalt formulations and industrial applications, classified under the tariff item for asphaltites and asphaltic rocks.
2714.90.00Grahamite Asphaltite
Grahamite is a hard, brittle natural asphaltite sourced from vein deposits. It is used in foundry cores, electrical insulation, and as a carbon source due to its fracture-resistant properties and high carbon content.
2714.90.00Impsonite Asphaltite
Impsonite is an intermediate-hardness natural asphaltite used in carbon electrodes and specialty applications. Mined from outcrops, it bridges gilsonite and glance pitch in properties, and is classified under the tariff item for asphaltites.
2714.90.00Natural Asphalt (Trinidad Lake Asphalt)
Natural asphalt, such as Trinidad Lake Asphalt, is a naturally occurring asphalt lake deposit that is pure and unrefined. It is shoveled directly from the lake and prized for high-quality road surfacing and waterproofing applications.
2714.90.00Natural Bitumen
Natural bitumen is a naturally occurring viscous mixture of hydrocarbons found in oil sands and tar pits. It is extracted directly from geological deposits and falls under the tariff item for other natural bitumen and asphalt.
2714.90.00Tar Sands (Athabasca Bitumen Ore)
Tar sands, such as Athabasca-type, consist of sand grains coated with natural bitumen. They are mined for bitumen recovery and are classified under the tariff item for bituminous or oil shale and tar sands.
