2811.29.50.00 - Other 🖩

This classification, 2811.29.50.00, encompasses inorganic oxygen compounds of nonmetals that are not specifically enumerated elsewhere within the broader category of "Other inorganic oxygen compounds of nonmetals." It serves as a residual category for such substances that do not fall under more specific subheadings within the 2811.29 group. Examples might include specific oxides or peroxides of nonmetallic elements not otherwise detailed.

Distinguishing this category from its siblings is crucial for accurate classification. For instance, 2811.29.10.00 specifically covers arsenic trioxide, while 2811.29.20.00 is for selenium dioxide, and 2811.29.30.00 is designated for sulfur dioxide. This code, 2811.29.50.00, therefore covers inorganic oxygen compounds of nonmetals that are *not* arsenic trioxide, selenium dioxide, or sulfur dioxide. The key differentiator lies in the specific chemical identity of the compound and its place within the established hierarchical structure of the Harmonized Tariff Schedule.

As this classification is a leaf node, there are no further subcategories. Therefore, the focus for classification under 2811.29.50.00 rests entirely on identifying an inorganic oxygen compound of a nonmetal that is not specifically listed in preceding subheadings at this level. Classification will rely on detailed chemical analysis and comparison against the precise definitions of the more specific sibling categories, ensuring that the substance in question does not meet the criteria for any of them.
