Product description
The subject product is an in vitro radioimmunoassay (RIA) kit for protein/peptide detection. The assay procedure follows the basic principle of radioimmunoassay, whereby there is competition between a radioactive and a non-radioactive antigen for a fixed number of antibody binding sites. The kit contains the following components (all stated to be freeze-dried): a standard (synthetic peptide); diluted primary antiserum (rabbit anti-peptide antiserum (host animal: rabbit)); iodine-125 (125I) labeled peptide; diluted secondary antisera (goat anti-rabbit antiserum and normal rabbit serum); and inorganic buffering agents. You indicate in your letter that the kit is designed for research use only. You assert that the kit is properly classified under subheading 3822.00.1090 HTSUS, which provides for: “Diagnostic or laboratory reagents on a backing, prepared diagnostic or laboratory reagents, whether or not on a backing, other than those of heading 3002 or 3006: Containing antigens or antisera: Other.” However, in light of our determination that the essential character of the kit is imparted by the antiserum components, the kit would be excluded from classification under subheading 3822.00.1090, HTSUS, by the language contained in Harmonized System Explanatory Note 38.22, HTSUS, and Harmonized System Explanatory Notes 30.02(C) and 30.02(E), HTSUS.
