281640

Oxides, hydroxides and peroxides, of strontium or barium

Heading 2816Hydroxide and peroxide of magnesium; oxides, hydroxides and peroxides of strontium or barium

Chapter 28: Inorganic chemicals

Plain-language overview

Use HS-6 281640 when importing or exporting oxides, hydroxides, and peroxides of strontium or barium. For example, if you're shipping strontium oxide in bulk for use in ceramics, this is the correct code.

This code specifically covers strontium and barium compounds, distinguishing them from other inorganic chemicals. For instance, HS-6 281610 pertains to magnesium hydroxides, which are used in different applications like water treatment.

When classifying under this heading, it’s important to note that while both strontium and barium compounds share similar chemical properties, they are used in distinct industries, such as electronics and glass manufacturing.

If you're dealing with a shipment of barium hydroxide for use in chemical synthesis, HS-6 281640 is the precise classification to ensure compliance with customs regulations.
