Product classification
HS code for X-ray contrast media: 3006.30
Pharmaceutical goods, opacifying preparations for x-ray examinations, diagnostic reagents designed to be administered to the patient.
Classification of X-ray contrast media under HS 3006.30
X-ray contrast media are classified under HS code 3006.30. This classification is governed by Chapter 30 of the Harmonized System, which pertains to pharmaceutical products. Heading 3006 is a specialized heading for "Pharmaceutical goods specified in Note 4 to this Chapter." Subheading 3006.30 specifically identifies "Opacifying preparations for X-ray examinations; diagnostic reagents designed to be administered to the patient." The classification criteria are twofold: the intended use must be for diagnostic imaging, and the substance must be designed for administration to a human or animal patient. These substances work by altering the absorption of X-rays in the body, thereby enhancing the contrast of internal organs or blood vessels on the resulting image. Because these are medical preparations intended for internal use, they are classified as pharmaceutical goods rather than general chemical products.
- Covers
- Iodinated contrast media (ionic and non-ionic)
- Barium sulfate suspensions for oral or rectal use
- Gadolinium-based contrast agents (when used for X-ray/CT)
- Microbubble contrast agents for diagnostic imaging
- Diagnostic reagents for patient administration
- Also under 3006.30
- Omnipaque (iohexol)
- Magnevist (gadopentetate dimeglumine)
- E-Z-HD (barium sulfate)
- Cardiolite (technetium sestamibi)
- Visipaque (iodixanol)
Codes often confused with 3006.30
Common mistake. A common misclassification occurs with HS code 3822.00, which covers diagnostic or laboratory reagents. However, 3822.00 is reserved for reagents used in vitro (outside the body), whereas 3006.30 is strictly for reagents administered to the patient. Another error involves classifying barium sulfate as a simple chemical under 2833.27; while chemically correct, once it is prepared as a contrast medium, the pharmaceutical heading 3006.30 takes precedence.
Top exporters and importers of HS 300630 (the code used for X-ray contrast media), 2025
In 2025, the largest exporter of HS 300630 (the code used for X-ray contrast media) in UN Comtrade data was Germany, with 25% of world exports; the largest importer in UN Comtrade data was the United States, with 28% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 300630, not only X-ray contrast media.

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).
