 Storage classes allow you to trade off between the cost of storage and the cost of accessing data. Every object stored in R2 has an associated storage class.

+## Change storage class for objects
+
+You can change the storage class of an object which is already stored in R2 using the [`CopyObject` API](https://docs.aws.amazon.com/AmazonS3/latest/API/API_CopyObject.html).
+
+Use the `x-amz-storage-class` header to change between `STANDARD` and `STANDARD_IA`.
+
+An example of switching an object from `STANDARD` to `STANDARD_IA` using `aws cli` is shown below:
+
+```sh
+aws s3api --endpoint-url https://<ACCONUT_ID>.r2.cloudflarestorage.com \
+  --copy-object \
+  --bucket bucket-name \
+  --key path/to/object.txt \
+  --copy-source bucket-name/path/to/object.txt \
+  --storage-class STANDARD_IA
+```
