# Disclaimers

Under the Russian Federal Law No. 38-FZ "On Advertising", ads for certain products and services must include a disclaimer. Specific requirements for disclaimers vary by ad category:

- For dietary supplements and alcoholic beverages, the disclaimer is required and must cover at least 10% of the banner area.
- For medical products, the disclaimer ("Consult a doctor") is required and must cover at least 5% of the banner area.
- For real estate and other regulated categories, the disclaimer is required and must be clearly visible during an ad impression.

## Banner ads

This format supports ad serving with any type of disclaimer. Partners don't have to worry about legal compliance because we handle full creative rendering to meet all regulatory standards.

Partners are only required not to resize the WebView after our markup is applied.

## Native ads

By default, ads with disclaimers are disabled for new partners. To enable these ads:

- The SSP partner must comply with all legal requirements.
- Yandex DSP verifies that creatives render correctly.
- Yandex DSP activates this demand for the partner.

#### Sample response with a disclaimer

- `seatbid.bid.adm.native.ext.disclaimer`: Object that contains all disclaimer information, where:
    - `percent`: Specifies the disclaimer-to-ad size ratio as a percentage.

``` json

        "isEcom": false
      }
    }
  }
}
```
