Sub-classifications

Commodity Code
Description

Overview

This HTS category, 2816.40, encompasses oxides, hydroxides, and peroxides specifically derived from strontium and barium. These are inorganic chemical compounds characterized by the presence of strontium (Sr) or barium (Ba) combined with oxygen, hydrogen, or a peroxide group. Examples of such substances include strontium oxide (SrO), strontium hydroxide (Sr(OH)2), barium oxide (BaO), and barium peroxide (BaO2), among others.

It is crucial to distinguish this category from its sibling, 2816.10.00.00, which exclusively covers magnesium-based oxides, hydroxides, and peroxides. While both fall under the broader heading for oxides, hydroxides, and peroxides of certain metals, the key differentiating factor for 2816.40 is the metallic element – it applies only to strontium and barium compounds, excluding any magnesium-derived substances.

Further subdivisions within 2816.40 are based on the specific metal. Subcategory 2816.40.10.00 pertains to compounds of strontium, whereas 2816.40.20.00 is designated for compounds of barium. This distinction allows for more precise classification and facilitates specific trade data tracking for these distinct chemical families.
