HS Code 3006.30 – Pharmaceutical goods; opacifying preparations for x-ray examinations, diagnostic reagents designed to be administered to the patient
HS code 3006.30 is the 6-digit subheading for pharmaceutical goods, opacifying preparations for x-ray examinations, diagnostic reagents designed to be administered to the patient. It is used for iodine-based contrast media, gadolinium-based contrast agents (for MRI), barium sulfate preparations, technetium-99m diagnostic agents and glucose solutions for PET scans.
What HS 3006.30 covers
This category covers pharmaceutical goods such as opacifying preparations for X-ray examinations and diagnostic reagents designed to be administered to the patient. These products are indispensable for modern diagnostic medicine, enabling clear visualization of internal structures and the detection of various diseases. The international trade involves specialized pharmaceutical companies, supplying hospitals, imaging centers, and diagnostic laboratories worldwide. Strict regulatory oversight ensures the safety and efficacy of these agents, which are directly introduced into the human body. Key considerations include patient safety profiles, imaging clarity, and the development of new, less invasive diagnostic tools. The market is driven by the increasing demand for accurate and early disease detection across a wide range of medical specialties.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
