Products classified under Tariff item 2825.70
Ammonium Heptamolybdate Tetrahydrate
Ammonium heptamolybdate tetrahydrate is a crystalline inorganic salt that serves as a soluble source of molybdenum, commonly used in fertilizers, catalysts, and laboratory reagents. Although it is a molybdate salt, its classification under this tariff item is based on its molybdenum oxide content and the absence of a more specific heading. The product is presented as a separate chemically defined compound, consistent with Chapter 28's scope.
2825.70.00Molybdenum Blue Oxide
Molybdenum blue oxide is a reduced molybdenum oxide consisting of a mixture of molybdenum dioxide (MoO2) and molybdenum trioxide (MoO3). It is used primarily in steel alloying and powder metallurgy applications. As a mixed molybdenum oxide, it falls under tariff item 2825.70.00 for molybdenum oxides and hydroxides.
2825.70.00Molybdenum Dioxide Powder (MoO2)
Molybdenum dioxide (MoO2) powder is a chemically defined inorganic oxide used as an intermediate in reduction processes for producing molybdenum metal and in pigment and alloy manufacturing. It is classified under tariff item 2825.70.00 as a molybdenum oxide, consistent with Chapter 28 notes for separate chemically defined compounds.
2825.70.00Molybdenum Pentoxide
Molybdenum pentoxide, also known as molybdenum(VI) oxide (MoO3), is a pure crystalline form used in research and thin-film deposition. It is a chemically defined molybdenum oxide and is classified under tariff item 2825.70.00, consistent with Chapter 28's coverage of separate chemically defined compounds.
2825.70.00Molybdenum Trioxide Powder (MoO3)
