Is there a requirement under eHBL such that a marine carrier 9000 series cargo needs to move once in its entirety on to an 8000 then deconsolidated on to multiple 8000?

There is no such requirement. When the 8000 eHBL has been transmitted, the cargo moves under that bonded freight forwarder 8000 CCN to the sublocation code / warehouse listed in the eHBL data set and as decided by the freight forwarder.  If the 8000 code is non-bonded, the eHBL sublocation code must match that of the primary carrier, and there would need to be paper re-manifest to move it out of the terminal.
