HS Code for X-ray contrast media

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.

Products Included

• 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

Common Misclassification

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.

FAQ
