# Seller products

Create, update, list and get your products (SKUs). Each operation documents its fields.

Prices and declared values per country are returned only when you ask for them with `fields=seller_product_info_by_country` on **Get** and **List**.

## Minimum shelf life

`inbound_minimum_shelf_life` and `storage_minimum_shelf_life` are optional and accepted on **Create Seller Product** and **Update Seller Product**. Both are expressed in **days**.

-   Each value must be an integer greater than or equal to 1. `null` is not accepted.
    
-   When both values are set, `inbound_minimum_shelf_life` must be greater than or equal to `storage_minimum_shelf_life`. Otherwise the request returns `400` with `errorCode` `INBOUND_MINIMUM_SHELF_LIFE_BELOW_STORAGE`.
    
-   On update, omitted fields keep their stored value, and the rule above is checked against the value already stored for the field you do not send.
