Heading 2825

Hydrazine and hydroxylamine and their inorganic salts; other inorganic bases; other metal oxides, hydroxides and peroxides

19 declarable lines

Heading 2825 covers hydrazine, hydroxylamine and their inorganic salts, plus a range of inorganic bases and metal oxides, hydroxides and peroxides not provided for in other headings. The heading is split first by the specific metal or compound, with separate lines for lithium, vanadium, nickel, copper, germanium and zirconium, molybdenum, antimony and beryllium. Compounds not named in the earlier subheadings fall to the residual Other lines at the end of the heading.

Products in this heading

How to choose the right subheading

Identify the exact chemical: oxide, hydroxide, peroxide, or hydrazine/hydroxylamine type.
Name the metal or cation, since most subheadings here are metal specific.
Check whether the compound is named in an earlier heading of chapter 28 before using 2825.
For copper, decide between cupric oxide, cuprous oxide and copper hydroxides.
For germanium and zirconium products, decide between germanium dioxide, zirconium dioxide and the Other line.
