I don't think so, but last year we dealt with Allen and he was told to take away the empty stillage, but he didn't want to. I think he was going to charge you more to take it away.
I have allowed disposal in my quotation already. So let me know if you can get your freight forwarder to dispose. But I think they will charge you extra. They would have to come back after show to pick it up and then disposal fees.
