Triple tagged vlans?

[bpbp-heyoo]

Have a circuit being delivered that will have 3 vlan tags ie "QinQinQ". I haven't encountered this before so please excuse the ignorance.

Can I deliver that transparently out another port? Or alternatively pop the outermost tag and deliver QinQ to where it needs to go?
