HS Code for Barium oxide

2816.40 Oxides, hydroxides and peroxides, of strontium or barium
Chemicals
View full HS code details

Barium oxide is classified under HS code 2816.40. This code is part of Chapter 28, which encompasses inorganic chemicals. Heading 2816 specifically covers the oxides, hydroxides, and peroxides of strontium or barium. Barium oxide (BaO), also known as baryta, is a white, hygroscopic compound obtained by the thermal decomposition of barium carbonate or the oxidation of elemental barium. The classification is determined by General Interpretative Rule 1, as the product is specifically named in the subheading text for 2816.40. It is important to distinguish between the chemically pure or commercially pure barium oxide found in Chapter 28 and the natural mineral forms found in Chapter 25. Only the synthetic or chemically refined compound belongs in 2816.40. This substance is widely used in the manufacture of optical glass, cathode ray tubes, and as a catalyst in various organic chemical reactions, as well as a drying agent for solvents.

Products Included

  • Barium oxide (BaO)
  • Barium hydroxide
  • Barium peroxide
  • Anhydrous barium oxide
  • Barium hydrate

Common Misclassification

A common misclassification occurs with natural barium sulfate or natural barium carbonate, which are classified under 2511.10 and 2511.20 respectively. These are minerals rather than refined chemicals. Additionally, barium carbonate (synthetic) is classified under 2836.60. Importers often confuse these because they are all barium-based industrial chemicals, but the oxygen-based compounds (oxides/peroxides) are strictly isolated to 2816.40.
