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

HTS Code 2816 encompasses metallic hydroxides and peroxides, specifically those of magnesium, strontium, and barium. This category is situated within Section VI, Chapter 28, which deals with inorganic chemicals. The classification primarily focuses on these compounds based on their chemical composition and metallic element.

Unlike sibling categories in the broader HTS structure, which might cover live animals, agricultural products, or mineral substances, HTS 2816 is exclusively focused on specific inorganic chemical compounds. Its parent chapter, Chapter 28, serves as a broad grouping for inorganic chemicals, and 2816 delves into a precise subset of these, namely the hydroxides and peroxides of particular alkaline earth metals.

Within HTS 2816, further subdivisions differentiate based on the specific metal. 2816.10.00.00 specifically covers hydroxide and peroxide of magnesium. The remaining portion of the category, 2816.40, is dedicated to the oxides, hydroxides, and peroxides of strontium or barium, indicating a clear distinction in the chemical constituents that drives the subclassification.
