3822.19.00.10 - Containing methyl chloroform (1,1,1-trichloroethane) or carbon tetrachloride

This category, HTS 3822.19.00.10, specifically classifies diagnostic or laboratory reagents that contain either methyl chloroform (also known as 1,1,1-trichloroethane) or carbon tetrachloride. These substances are typically included for their solvent properties or as active components within the reagent formulation. The key defining characteristic for this subcategory is the presence of one or both of these chlorinated hydrocarbons.

It is important to distinguish this entry from its sibling, 3822.19.00.30, which covers "Other" reagents within the same broader heading. While both fall under "Other" diagnostic or laboratory reagents not specifically listed elsewhere in Chapter 38, HTS 3822.19.00.10 has the exclusive requirement of containing methyl chloroform or carbon tetrachloride. If a reagent does not contain these specific chemicals, it would likely be classified under the "Other" sibling category.

As this is a leaf node in the HTS, there are no further subdivisions. Therefore, classification into HTS 3822.19.00.10 depends solely on the confirmed presence of methyl chloroform or carbon tetrachloride in the diagnostic or laboratory reagent. Importers and exporters should carefully review the composition of their goods to ensure accurate classification, as the presence of these specific regulated substances dictates placement within this particular subcategory.
