DeleteImportedKeyMaterial

If you import key material into a KMS key, you can delete the imported key material at any time by using the DeleteImportedKeyMaterial operation. When you delete imported key material from a KMS key, the key state of the KMS key changes to PendingImport and the KMS key cannot be used in any cryptographic operations. For details, see Delete imported key material.

The following example shows an AWS CloudTrail log entry generated for the DeleteImportedKeyMaterial operation.
