For SH registered domain, I think its best your professional team handles the classification. The bulk of the fees goes to you and it wont hurt if your team handle the description and classification.
Proper classification/sales will be a win-win to both creative and SH. if classification is left to Creative alone and its not done properly, it might reduce the chance of the name selling, which does not benefit either party.
my humble suggestion and happy new year to you…
