Last updated: April 2026 dataContrast media and diagnostic agents used to enhance visibility in radiological imaging fall under FDA oversight as drugs or medical devices, requiring compliance with applicable premarket approval or 510(k) clearance pathways before US entry. The US tariff schedule distinguishes preparations containing antigens or similar immunological components (3006301000) from other opacifying preparations (3006305000), a split that affects both classification and regulatory review. Germany and Norway are the leading suppliers, reflecting the concentration of advanced pharmaceutical manufacturing in Western Europe. Importers should verify that each shipment's formulation aligns with the correct 10-digit line, as misclassification between the antigen-containing and non-antigen lines is a recurring audit issue.

The schedule separates preparations containing antigens or similar immunological components (3006301000) from all other opacifying preparations (3006305000). The distinction turns on the product's active ingredient profile, so importers must review the formulation carefully — misclassification can trigger duty discrepancies and FDA admissibility complications.
Contrast agents are regulated as drugs or medical devices by FDA. Depending on the product, the importer must demonstrate either an approved New Drug Application (NDA), an Abbreviated NDA, or 510(k) clearance. Shipments from unapproved establishments or without valid marketing authorization are subject to refusal of admission. Consult a licensed customs broker or regulatory counsel to confirm admissibility requirements for a specific formulation.
