A pesticide device being imported did not have an EPA establishment number, as required by 40 CFR 156.10(f), on the label. As such, the device was denied entry into the U.S. The device, Healthy Climate 41 W-D, is a germicidal lamp. Additionally, a Notice of Arrival was not issued until after the device arrived in the U.S., which is a violation of 19 CFR 12.112(a).
