FDA Marks Radiation Devices as Safe but Snooze-Worthy
Published Date: 4/30/2026
Rule
Summary
The FDA is officially putting radiation therapy marking devices into Class II, meaning they’ll have special safety rules but less red tape than before. This change helps make sure the devices are safe and effective while making it easier for patients to get new, helpful tech. The new rules took effect on April 30, 2026, but the classification has been in place since December 10, 2021, so manufacturers should already be on board.
Analyzed Economic Effects
4 provisions identified: 1 benefits, 1 costs, 2 mixed.
Devices moved to Class II
The FDA has classified radiation therapy marking devices into Class II (special controls). This classification is effective April 30, 2026 and was applicable December 10, 2021. FDA says this will provide reasonable assurance of safety and help enhance patients' access to new devices by reducing regulatory burdens.
510(k) Premarket Notification Required
Radiation therapy marking devices are subject to premarket notification under section 510(k) of the FD&C Act. FDA has not exempted this device type under section 510(m), so manufacturers must submit a 510(k) to market these devices.
New Special Controls: Testing & Labeling
The FDA codified special controls at 21 CFR 892.5785 that manufacturers must meet, including design verification and validation studies (colorant compatibility, reproducible delivery, marker visibility duration), accuracy and reproducibility of needle penetration depth, sterility and reprocessing validation, electrical and electromagnetic testing, software verification and hazard analysis, shelf-life studies, and specific labeling (operation, reprocessing instructions, disposal, and shelf life). A device must meet these controls to be classified as Class II and avoid automatic Class III assignment.
Scope Exclusions for This Classification
The Class II classification for 'radiation therapy marking device' does not include devices with reusable or reprocessed needles, or devices intended for diagnostic, therapeutic, or aesthetic use or to deliver other products for those uses. Those excluded device types remain outside this codified classification.
