HS-4 · Heading
2816 — Hydroxide and peroxide of magnesium; oxides, hydroxides and peroxides of strontium or barium
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-4 2816 when importing hydroxides and peroxides of magnesium or oxides, hydroxides, and peroxides of strontium or barium. For example, if you're shipping magnesium hydroxide for use in industrial applications, this code applies.
To differentiate between the two subheadings, consider the specific chemical composition. HS-6 281610 covers magnesium hydroxide and peroxide, while HS-6 281640 is for strontium or barium compounds. If your product contains magnesium, use the first code; if it contains strontium or barium, choose the second.
When assessing your product, pay attention to the intended use. Magnesium hydroxide is often used in pharmaceuticals and water treatment, while strontium or barium oxides are typically found in ceramics and glass manufacturing. This can help clarify which HS-6 line is appropriate.
