When to use

Optional for products that require certain information to be shown in your Shopping ads or free listings, for example due to local regulations and for supported voluntary certifications as described below.

If you don't provide certification information for your products, Google may automatically add it based on GTIN and MPN data. This helps ensure that your products' certification information is shown accurately on Google. You can correct or update the information by submitting new certification attributes and sub-attributes for your products.

Format

Follow these formatting guidelines to make sure Google understands the data you're submitting. Learn when and how to submit your product data.

Formatting specifications
Technical name	`certification`
Type	Unicode characters (Recommended: ASCII only)
Sub-attributes	Authority `[certification_authority]` (Required): The authority or certification body responsible for issuing the certification. Name `[certification_name]` (Required): The name of the certification. Code `[certification_code]` (Sometimes Required): The code of the certification. Check the details of the certification to understand if this sub-attribute is required. Value `[certification_value]` (Sometimes Required): The value of the certification. Check the details of the certification to understand if this sub-attribute is required.
Repeated field	Yes
Schema.org property (What’s this?)	Product.hasCertification Type: Certification (specify properties issuedBy, name, and certificationIdentification)

File format examples

To ensure your attribute is recognized correctly, use the formatting specific to your data source type.

Data source format	Examples
Text (TSV or CSV) data sources	Format the attribute header by including the sub-attributes you’re submitting. Include certification `[certification]`, and then, in parentheses, add the names of the sub-attributes that you want to submit separated by a colon ( : ). Don't use quotation marks. The authority `[certification_authority]` and name `[certification_name]` sub attributes are always required. For example, to submit 3 sub-attributes authority `[certification_authority]`, name `[certification_name]`, and code `[certification_code]`, submit the attribute header: `certification(certification_authority:certification_name:certification_code)` Example header and values: For EPREL: `certification(certification_authority:certification_name:certification_code)` `EC:EPREL:123456` For Vehicles: `certification(certification_authority:certification_name:certification_value)` `ADEME:Vehicle_CO2_Class:C` If you don't include the sub-attributes in the attribute header, we’ll assume that your values include 3 sub-attributes in this order: Authority `[certification_authority]` Name `[certification_name]` Code `[certification_code]` If only some of your products have all sub-attributes values as required by the attribute header, you still need to use colons ( : ) as separator placeholders for the empty / non-specified sub-attribute values.
XML data sources	`<g:certification> <g:certification_authority>EC</g:certification_authority> <g:certification_name>EPREL</g:certification_name> <g:certification_code>123456</g:certification_code> </g:certification>` `<g:certification> <g:certification_authority>ADEME</g:certification_authority> <g:certification_name> Vehicle_CO2_Class </g:certification_name> <g:certification_value>C</g:certification_value> </g:certification>`

How to encode in Schema.org

The following example illustrates how to specify certification information using structured data. The example specifies an EPREL energy efficiency label for an LED.
