"Reach the supervision warehouse" is a 4PX Express checkpoint. The parcel has cleared customs and has now arrived at a bonded or supervised warehouse, a facility that handles goods under customs oversight. It is a waypoint on the way to you, not the final delivery depot.
No, this message by itself is normal. It appears after "Customs release", so the parcel has already passed the customs step. It is not an exception or a sign of a problem. If the parcel stays here for longer than the previous steps took, that is worth watching, but this scan alone does not indicate a delay.
In every observed case, the next update is "Handed over between customs and delivery". This means the parcel has left the warehouse and been passed on for the next leg of its journey towards your country's delivery network. From there it continues to a local carrier for final delivery.
