3824.99.33.00 - Of mercury

This HTS subcategory, 3824.99.33.00, specifically classifies chemical products and preparations that are "Of mercury." This classification encompasses a wide range of substances and mixtures where mercury is a significant constituent, forming the basis for their chemical properties and intended use. These are not simple mercury compounds but rather more complex preparations or mixtures where mercury plays a defining role, and they are not more specifically provided for elsewhere within Chapter 38 or other HTS chapters.

This category is distinguished from its siblings by its exclusive focus on mercury-containing products. For instance, while 3824.99.31.00 covers items of bismuth, and 3824.99.34.00 through 3824.99.36.00 deal with molybdenum, tungsten, and vanadium respectively, this subcategory is solely concerned with the classification of goods whose primary characteristic or active component is mercury. Similarly, it differs from 3824.99.32.00, which pertains to hydrosulfite and sulfoxylate compounds, by its focus on mercury's chemical contributions.

As this HTS code represents a leaf node, there are no further subcategories branching from this point. Therefore, the focus for classification purposes under 3824.99.33.00 is on accurately identifying the presence and significance of mercury within a given chemical product or preparation. Classification decisions will hinge on detailed chemical analysis, understanding the intended application of the mixture, and ensuring that the product is not classifiable under a more specific heading or subheading elsewhere in the HTS.
