Products classified under Tariff item 2530.90.00.00
Agglomerated Meerschaum Rods Unworked
Meerschaum powder agglomerated into rods or sticks, not further worked after molding. This product is explicitly listed in the chapter notes for tariff item 2530.90.00 as agglomerated meerschaum in rods or similar forms.
2530.90.00Calcined Earth Colors Mix
Mixture of calcined natural earth colors like ochers and umbers for artist pigments. This product is classifiable under tariff item 2530.90.00 as earth colors, whether or not calcined or mixed together, provided the iron content is below 70% by weight.
2530.90.00Goethite Micaceous Iron Oxide Ore
Micaceous variety of goethite iron oxide with flaky platelets, sourced from sedimentary iron formations. This natural micaceous iron oxide is unprocessed and classifiable under tariff item 2530.90.00, which explicitly includes natural micaceous iron oxides.
2530.90.00Greenland Cryolite Crystals
Natural cryolite crystals from the Ivigtut deposit in Greenland, unprocessed and in their natural mineral state. These crystals are used primarily as a flux in metallurgical applications, particularly aluminum smelting, and fall under tariff item 2530.90.00 as mineral substances not elsewhere specified.
2530.90.00Ivigtut Cryolite Specimen
Museum-grade natural cryolite crystals from the historic Ivigtut mine, in their natural specimen form for geological collections or research. These unworked mineral specimens are classifiable under tariff item 2530.90.00 as mineral substances not elsewhere specified, provided they are not polished or processed.
2530.90.00Limonite Micaceous Iron Oxide Fines
Fine particles of limonite-based micaceous iron oxide, a hydrated iron ore with platy morphology from natural deposits. This natural micaceous iron oxide is classifiable under tariff item 2530.90.00 as explicitly listed in the chapter notes.
2530.90.00Micaceous Iron Oxide Flakes
Coarse, plate-like flakes of natural micaceous iron oxide mined from specular hematite deposits, prized for anti-corrosive properties. These unworked natural flakes are classifiable under tariff item 2530.90.00 as natural micaceous iron oxides.
2530.90.00Micaceous Iron Oxide Lumps
Natural micaceous iron oxide in lump ore form before grinding, used as raw feed for pigments. This product is classifiable under tariff item 2530.90.00 as natural micaceous iron oxide, explicitly listed in the chapter notes.
2530.90.00Mixed Natural Mineral Pigments
Blend of natural ochers, siennas, and umbers mixed for pigment use, calcined. This product is classifiable under tariff item 2530.90.00 as mixed earth colors with iron content below 70%, as specified in the chapter notes.
2530.90.00Natural Chiolite Mineral
Natural chiolite, a rare sodium aluminum chloride fluoride mineral found in cryolite deposits, used in specialty fluxes. This mineral is unprocessed and classifiable under tariff item 2530.90.00 as a mineral substance not elsewhere specified, similar to natural cryolite.
2530.90.00Natural Cryolite Granules
Naturally occurring granular cryolite from weathered deposits, minimally handled after mining. The granules remain in their natural mineral form without artificial processing, making them classifiable under tariff item 2530.90.00 as mineral substances not elsewhere specified.
2530.90.00Natural Cryolite Ore
Raw sodium aluminum fluoride mineral extracted from deposits in Greenland, used primarily as a flux in aluminum smelting. This natural cryolite ore is unprocessed and classifiable under tariff item 2530.90.00 as a mineral substance not elsewhere specified.
2530.90.00Natural Micaceous Iron Oxide Powder
A fine powder derived from natural micaceous iron oxide deposits, characterized by its flaky, mica-like structure and high iron content. This natural powder is classifiable under tariff item 2530.90.00 as natural micaceous iron oxide, provided it is not chemically processed.
2530.90.00Specular Hematite Micaceous Iron Oxide
Natural specular hematite ore featuring micaceous iron oxide with metallic luster and platy crystals, extracted from geological deposits. This natural mineral matches the legal definition of natural micaceous iron oxide and is classifiable under tariff item 2530.90.00.
2530.90.00Unprocessed Cryolite Flux Ore
Crude cryolite ore directly from mining operations, containing typical gangue materials, destined for aluminum flux production. This raw, unbeneficiated mineral is classifiable under tariff item 2530.90.00 as a mineral substance not elsewhere specified.
