2852.90.05.00 - Albuminates, tannates and phosphides of mercury 🖩

This HTS category, 2852.90.05.00, specifically covers albuminates, tannates, and phosphides of mercury. These are inorganic or organic compounds of mercury where mercury is combined with albumin, tannic acid, or phosphorus, respectively. Such compounds are often used in specialized industrial or laboratory applications where the specific chemical properties of these mercury derivatives are required.

Distinguishing this category from its sibling, 2852.90.90.00, is crucial. While both fall under the broader heading of "Other" inorganic or organic compounds of mercury (excluding amalgams), 2852.90.05.00 is reserved for the precise chemical entities of albuminates, tannates, and phosphides. The sibling category would encompass any other mercury compounds not explicitly listed elsewhere within heading 2852.

As a leaf node, 2852.90.05.00 does not have further subcategories. Therefore, the focus for classification within this specific code lies in accurately identifying the product as an albuminate, tannate, or phosphide of mercury. Importers and exporters must ensure their documentation clearly indicates the specific nature of the mercury compound to ensure correct classification under this precise sub-heading.
