RPRICE is "right-on" with his advice.

Freight forwarders consolidate shipments all the time. That is what they do.

Your container is in the control of a specific freight forwarder. You will want to contact them directly for instructions, addresses, documentation preparation cost.

Consolidating may be cheaper, but not free. If the container already has an established shipping date, it may complicate matters. Boats don't wait for anyone.
