KMS is a region-based service. KMS resources, and limits of resource use, are relatively independent for each user in different regions. For supported regions, see KMS Regions.

CMK quota

Each user can create up to 200 CMKs in each region.

Any user needing to create more than 200 CMKs can submit a ticket to Alibaba Cloud.
