2827.60.10.00 - Of calcium or of copper

This HTS category, 2827.60.10.00, specifically classifies iodides and iodide oxides that are derived from calcium or copper. These inorganic chemical compounds are characterized by the presence of iodine within their molecular structure, forming salts or oxides with either calcium or copper. The classification hinges on the elemental composition, focusing on the iodide form of these specific metals.

Distinguishing this category from its siblings is crucial for accurate classification. While all fall under "Iodides and iodide oxides," 2827.60.10.00 is distinct from 2827.60.20.00, which exclusively covers potassium iodides. Similarly, it differs from the "Other" category (2827.60.51.00), which encompasses a broader range of iodides and iodide oxides not otherwise specified, such as those made from different metals. Therefore, the presence of calcium or copper as the metallic component is the defining criterion for goods classified under this heading.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification within 2827.60.10.00 is definitive once the material is identified as a calcium or copper iodide or iodide oxide. Practical classification will rely on laboratory analysis or manufacturer declarations to confirm the elemental composition.
