# SKU list items

SKU list items are used to manually populate an [SKU list](https://docs.commercelayer.io/core-api-reference/sku_lists). The position determines the order of the SKU within the associated list.

{% hint style="warning" %}
SKU uniqueness is not enforced on SKU list. That means the same SKU can be associated with different SKU list items (even with different quantities) belonging to the same SKU list — as it happens for SKUs and line items in an order.
