That's good to hear. Thank you, and everyone else who has responded so far. I just contacted Hermes about sending my Kelly bag to the spa, so perhaps I'll take the opportunity at the same time to ask them about this issue as well when they get back to me.
UPDATE: My Hermes store advised that we do indeed need the CITES paperwork with us when we submit it to the spa. So I guess that answers that part of it. I still don't know yet if we can obtain it after-the-fact ourselves if we purchased it from a reseller that doesn't have it, but I think at this point it's not worth the risk.
