RETURNING YOUR RADON DETECTOR TO THE RADONOVA LAB WITH CANADA POST
Beginning August 29, 2025, the US requires a Customs Declaration ID and Duties to be prepared online, and if applicable, duties prepaid when shipping packages to the United States 🇺🇸
Radonova’s radon detectors are manufactured in the USA and are returned to the manufacturer in the USA for analysis; the radon detectors are not subject to additional duty or tax.
TARIFFS DO NOT APPLY when returning the radon detectors to the US Lab for analysis.
