Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the microplates are certified reference materials
Chapter Note 2 gives heading 38.22 precedence for certified reference materials, with subheading 3822.11 for medical diagnostics.
If the microplates are presented as empty plastic labware without antigens
If the microplates are not coated with diagnostic reagents, they may be classified as plastic articles under Chapter 39.
