3822.19.00.30 - Other

This HTS subheading, 3822.19.00.30, encompasses a broad category of prepared diagnostic or laboratory reagents that do not fall under more specific classifications within heading 3822. It includes reagents, whether or not mounted on a backing or presented in kit form, intended for diagnostic or laboratory use, but which are not otherwise specified. The key characteristic is their preparation for a specific analytical or testing purpose, going beyond simple chemical substances.

This classification serves as a residual category for diagnostic and laboratory reagents not specifically covered by subheadings like those containing methyl chloroform or carbon tetrachloride (3822.19.00.10). The distinction lies in the absence of these particular chemical components in the reagents classified under 3822.19.00.30. Therefore, if a reagent is prepared for diagnostic or laboratory use and does not contain methyl chloroform or carbon tetrachloride, it will likely be classified here.

As this is a leaf node, there are no further subcategories to introduce. Classification at this level requires careful consideration of the reagent's intended use and its precise chemical composition to ensure it is not better suited to a more specific HTS code within heading 3822 or another chapter. Common examples within this category might include certain blood typing reagents, immunological test kits, or specialized chemical indicators for laboratory analysis that do not fit into more granular descriptions.
