Missing unit_pricing_measure Attribute Warnings Coming to EU and Switzerland Google Merchant Center in March 2021

In the European Union and Switzerland, you may be required by local law to display unit pricing information for applicable products. For example, if you sell perfume in this region, it is required to provide the price per 10 milliliters in your ad or listing. Beginning in March 2021, we will show “Missing potentially required value” warnings when the unit_pricing_measure attribute is missing for products for which you may be required to display the price per unit. If a required attribute is omitted, your product(s) may be legally liable for non-compliance with applicable law.

If you receive this warning, either provide the missing attribute with a valid value or verify that your product is compliant without the attribute.
