3822.19.00.80 - Other

This HTS category, 3822.19.00.80, encompasses a broad range of diagnostic or laboratory reagents that are not specifically categorized under other subheadings within heading 3822. These are prepared chemical mixtures, films, or other substrates designed for analytical, diagnostic, or scientific laboratory use. Their purpose is to react with a specific analyte or to provide a standard for measurement, calibration, or quality control. Examples include ready-to-use test strips for detecting specific substances, calibration standards for analytical instruments, and reactive components for immunoassay kits, provided they do not meet the criteria for heading 3006.

This "Other" classification serves as a residual category for diagnostic or laboratory reagents that do not fall into the specific sibling category of 3822.19.00.40, which exclusively covers reagents containing methyl chloroform (1,1,1-trichloroethane) or carbon tetrachloride. Therefore, any diagnostic or laboratory reagent not containing these specific halogenated hydrocarbons will be classified here, assuming it meets the general criteria of heading 3822 and is not otherwise specified in a more precise subheading.

As this is a terminal classification, there are no further subcategories to introduce. The classification decision for goods falling under 3822.19.00.80 relies on a thorough analysis of the reagent's intended use, its chemical composition, and whether it can be distinctly identified within a more specific subheading. The absence of specific chemical constituents like those in the sibling category, and its role as a prepared diagnostic or laboratory reagent, are key factors in its placement.
