The fee the Clearinghouse charges, is merely for registering your trademark in TMCH. If you wish to participate in a Sunrise period of a TLD, there will likely be an additional cost to actually register your domain name in that TLD. This cost is not determined by the Clearinghouse but depends on the commercial model of the specific TLD. The Clearinghouse cannot register actual domain names and you will need to contact a domain name registrar if you wish to participate in a Sunrise period of a TLD.
