-* `replace_default_association` - (Optional) Whether this association should replace the association with the VPC's default security group that is created when no security groups are specified during VPC endpoint creation.

At most 1 association per-VPC endpoint should be configured with `replace_default_association = true`. `false` should be used when importing resources.
 
 ## Attribute Reference
 
 This resource exports the following attributes in addition to the arguments above:
 
 * `id` - The ID of the association.
+
+## Import
+
+In Terraform v1.5.0 and later, use an [`import` block](https://developer.hashicorp.com/terraform/language/import) to import VPC Endpoint Security Group Associations using `vpc_endpoint_id` together with `security_group_id`. For example:
+
+```terraform
+import {
+  to = aws_vpc_endpoint_security_group_association.example
+  id = "vpce-aaaaaaaa/sg-bbbbbbbbbbbbbbbbb"
+}
+```
+
+Using `terraform import`, import VPC Endpoint Security Group Associations using `vpc_endpoint_id` together with `security_group_id`. For example:
+
+```console
+% terraform import aws_vpc_endpoint_security_group_association.example vpce-aaaaaaaa/sg-bbbbbbbbbbbbbbbbb
+```
