Build the FHL XML document referencing the master air waybill number in the MasterWaybill element
List each house airway bill (HAWB) as a separate HouseWaybill element with its own shipper, consignee, commodity, and weight details
Ensure the sum of all HAWB weights matches the master AWB chargeable weight declared in the FWB
Include any special handling codes (SPH elements) at the house level for cargo requiring temperature control, DG, or other special care
Transmit the FHL to the carrier or ground handling agent prior to flight departure so the house details are available for customs and destination handling
Known gotchas
FHL is the house manifest at the consolidation level; it is distinct from the HAWB FWB message and must reference the master AWB number consistently
Weight discrepancies between the FHL house total and the master FWB will cause customs holds at destination; reconcile totals before transmission
Some origin customs authorities require the FHL to be submitted before uplift; others accept it at destination — confirm the regulatory requirement for each trade lane
