HAWB vs MAWB: Key Differences Every Freight Forwarder Must Know
HAWB (House Air Waybill) is the forwarder’s receipt to the shipper; MAWB (Master Air Waybill) is the airline’s contract with the forwarder. Both track cargo, but one is internal, the other airline-level.
Freight teams mix them because both documents share identical flight details and AWB numbers. In daily chaos, the smaller HAWB looks like a “copy” of the MAWB, so staff grab whichever prints first and forward it—triggering customs holds.
Key Differences
HAWB lists the actual shipper & consignee; MAWB lists the forwarder as shipper and its agent abroad as consignee. HAWB uses the forwarder’s prefix; MAWB uses the airline’s. HAWB moves under consolidation; MAWB flies the plane.
Which One Should You Choose?
Use HAWB for every individual customer shipment. Use MAWB only when you’re ready to tender the consolidated lot to the airline. If you’re the exporter, demand the HAWB for tracking; if you’re the airline, you’ll only ever see the MAWB.
Examples and Daily Life
Five suppliers send goods to LAX via one forwarder. The forwarder issues five HAWBs to each supplier, then creates one MAWB covering all cartons. At LAX, the agent splits the MAWB using the five HAWBs—each supplier tracks via the HAWB number, while the airline tracks via the single MAWB.
Can a shipment travel with only an MAWB?
No. Without a matching HAWB, customs can’t link consolidated cargo to individual shippers, causing delays and fines.
Do both documents have the same AWB number?
Never. The MAWB starts with the airline’s three-digit prefix; each HAWB uses the forwarder’s own prefix to avoid confusion.
Who signs the MAWB?
The airline’s cargo acceptance officer signs the MAWB; the freight forwarder signs the HAWB as the issuing party.
