A non-bonded 8000 freight forwarder can file eHBL for Customs clearance from the primary airline warehouse. The Customs release request will be on the eHBL 8000 CCN.  The airline warehouse will CACM / WACM to Arrive the airline MAWB.  The airline warehouse (primary terminal) must be subscribed to the CBSA Notices and in particular to the D4 Deconsolidation Notice.  When the MAWB is Arrived/ WACM and when the shipment is Customs cleared, the D4 Deconsolidation Notice will cascade, and the shipment will be authorized to move. Even if the 8000 CCN is non-bonded, the shipment can move to the sublocation of the bonded carrier or forwarder above it, in this case to the airline warehouse sublocation code.
