Heading 2816

Hydroxide and peroxide of magnesium; oxides, hydroxides and peroxides, of strontium or barium

3 declarable lines

Heading 2816 covers hydroxide and peroxide of magnesium, plus oxides, hydroxides and peroxides of strontium or barium. The heading splits first by the metal: one line for magnesium hydroxide and peroxide, and one group of lines for strontium and barium compounds. The strontium and barium group then splits again by metal.

Products in this heading

  • Magnesium hydroxide powder (brucite)
  • Magnesium peroxide
  • Strontium oxide
  • Strontium hydroxide
  • Barium oxide
  • Barium hydroxide
  • Barium peroxide
  • Magnesium hydroxide paste used as a flame retardant filler

How to choose the right subheading

  • Identify the metal in the compound: magnesium on one side, strontium or barium on the other.
  • Identify the form: oxide, hydroxide or peroxide, since the heading text lists all three.
  • For the strontium and barium group, choose the line by the specific metal.
  • Check that the product is a separate chemically defined compound of these metals, not a sulfate, carbonate or nitrate.

Often confused with

  • Sodium hydroxide (caustic soda)

    Sodium and potassium hydroxides have their own heading, separate from the magnesium and alkaline-earth products in 2816.

    Heading 2815
  • Aluminum hydroxide

    Aluminum oxide and aluminum hydroxide are classified in 2818, not with the magnesium compounds.

    Heading 2818
  • Barium sulfate

    Sulfates belong to heading 2833; 2816 covers only oxides, hydroxides and peroxides of barium.

    Heading 2833
  • Strontium carbonate

    Carbonates go to heading 2836; the strontium lines in 2816 are limited to oxides, hydroxides and peroxides.

    Heading 2836
  • Magnesium oxide (calcined magnesia)

    Magnesium oxide is provided for in heading 2519, while 2816 covers the hydroxide and peroxide.

    Heading 2519
