About RADIONUC

What does the FDA import refusal charge RADIONUC mean?

FDA uses RADIONUC for: radionuclide. Its published charge language reads: “Article appears to contain the radionuclide, Cesium-137, a poisonous and deleterious substance which may render it injurious to health.”

Is RADIONUC a food safety finding?

Yes. This site counts RADIONUC as a hazard finding, so a refusal citing it is on the hazard side of the hazard and paperwork split, whatever else the refusal cites.

What happens to a shipment refused under RADIONUC?

Under section 801(a) of the FD&C Act a refused entry has to be exported or destroyed, normally within 90 days of the notice of refusal. Bringing a product into compliance, for instance by relabelling, is something the importer asks FDA for before the decision is final. The notice itself and FDA's guidance govern a particular case; this page describes the published data and is not legal advice.
