Products classified under HTS 3822.19.00.10
ELISA Antigen Test Kit with Methyl Chloroform
A diagnostic reagent kit for enzyme-linked immunosorbent assay (ELISA) containing specific antigens and methyl chloroform (1,1,1-trichloroethane) as a solvent stabilizer. Used in clinical labs to detect viral infections like HIV or hepatitis. Classified under HTS 3822.19.0010 due to the presence of methyl chloroform in the prepared diagnostic reagents.
Carbon Tetrachloride Antibody Detection Strip
Prepared laboratory test strips on backing with immobilized antibodies and carbon tetrachloride preservative for detecting autoimmune disorders. Commonly used in hospital pathology labs for rapid point-of-care testing. Falls under HTS 3822.19.0010 specifically due to carbon tetrachloride content in the reagent formulation.
Methyl Chloroform Viral Antigen Microplate
96-well microplates coated with viral antigens preserved in methyl chloroform solution for high-throughput ELISA screening in research labs. Essential for COVID-19 serology and influenza diagnostics. HTS 3822.19.0010 classification applies due to the specific solvent in the prepared diagnostic reagent.
Antisera Preservation Solution with Carbon Tetrachloride
Liquid diagnostic reagent containing polyclonal antisera stabilized with carbon tetrachloride for immunological precipitation tests. Used in veterinary and human TB diagnostics. Classified under HTS 3822.19.0010 for diagnostic reagents containing this specific solvent.
Methyl Chloroform Allergy Test Panel
Diagnostic panel with multiple allergen antigens preserved in methyl chloroform for skin prick testing and in vitro RAST assays. Used by allergists for identifying IgE-mediated hypersensitivity. HTS 3822.19.0010 due to solvent content in the prepared diagnostic reagents on backing.
Carbon Tetrachloride Lyme Disease ELISA Kit
