New Warnings in Google Merchant Center for Missing Energy Efficiency Class in EU and Switzerland

In the European Union and Switzerland, it is required by local law to display energy efficiency class information with applicable products. Beginning in mid-January 2021, we’ll show “Missing potentially required value” warnings when the energy_efficiency_class attribute is missing for products for which you may be required to display energy efficiency class information. If a required attribute is omitted, your product(s) may be legally non-compliant and you, as the merchant, are legally liable.

To resolve this sort of issue, either provide the missing attribute with a valid value or verify that your product is compliant without the attribute.
