In retail inspections last year, Germany’s Federal Network Agency reviewed 2,400 device types. Of those, 58% failed to meet requirements, which means a total of 1.9 million sold devices are affected. In many cases, the issues didn’t result in major safety risks, such as missing CE marking or user manuals that were not offered in German.

However, the agency also found products including PV inverters and network switches with excessively high interference voltage, which in some cases could disrupt wireless devices, broadcasting and military signals. According to the agency, customs prevented the import of a total of 359,000 products. 8,202 shipments have been flagged as suspicious by customs, 89% of those were not compliant with regulations.
