3006.30.10.00 - Containing antigens or antisera

This HTS category, 3006.30.10.00, specifically covers opacifying preparations for X-ray examinations and diagnostic reagents designed to be administered to a patient that contain antigens or antisera. These products are crucial for medical imaging and in-vitro diagnostics, relying on the immunological properties of antigens and antisera to achieve their intended diagnostic or visualization function within the human body. Examples include contrast media containing specific antibodies or purified antigens used in serological testing or to highlight particular tissues or organs during radiological procedures.

This classification is distinct from its sibling category, 3006.30.50.00 (Other), which encompasses opacifying preparations and diagnostic reagents not containing antigens or antisera. While both subheadings fall under the broader category of diagnostic reagents and preparations, the presence or absence of antigens or antisera is the definitive distinguishing factor for classification under 3006.30.10.00. This ensures that products leveraging specific immunological responses are accurately categorized.

As a leaf node, there are no further subcategories within 3006.30.10.00. Classification at this level relies entirely on the product meeting the description of an opacifying preparation or diagnostic reagent intended for administration to a patient and crucially, containing antigens or antisera. Importers must ensure their goods align with these specific criteria to avoid misclassification.
