For decades an air waybill was a multi-copy paper form that travelled in an envelope taped to the cargo or handed to the airline’s station staff. Today, in most international air freight, the same information moves as an electronic message and the paper never exists at all. The name for that arrangement is the electronic air waybill, or e-AWB. If you import by air from China, it is worth understanding, because it changes what you receive, what you can rely on, and what can quietly go wrong.

What an e-AWB actually is
An air waybill is a contract of carriage between the shipper and the airline, and also a receipt for the goods and a source of shipment data. An e-AWB keeps all three functions but replaces the paper with data exchanged between the forwarder’s system and the airline’s system, using industry-standard messages. The data is what matters; a printout of it is only a convenience.
For the e-AWB to work, the shipper or forwarder must have an agreement with the airline that allows electronic contracts, and the countries at both ends must accept an electronic waybill as a valid contract. In practice, the forwarder handles all of this. What the importer sees is a PDF or a printed copy of the waybill data, plus an air waybill number that can be tracked. Our article on house versus master air waybills explains why there are usually two numbers, and which one you should quote when tracking.
How the number is built and why it is useful
An air waybill number has eleven digits. The first three identify the airline, the next seven are a serial number, and the last digit is a check digit that lets a system spot a mistyped number. That small design detail is why a tracking page can reject an AWB number you copied wrongly, rather than showing you someone else’s cargo.
Because the master waybill is issued by the airline and the house waybill by the forwarder, an importer who ships through a consolidator will usually be given both. Use the master number to follow the flight and the house number when you deal with the forwarder about your particular cartons.

The practical benefits are real but modest. Data reaches the destination airport before the aircraft lands, so the airline’s cargo system and the clearing agent can start preparing while the cargo is still in the air. Fewer hand-typed copies mean fewer transcription errors between the invoice, the waybill and the manifest. And nothing physical can be lost or delayed in a courier envelope, which used to be a genuine cause of cargo waiting at the terminal for paperwork.
What does not change is Customs. The bill of entry still has to be filed in the national system, and the values, quantities and description on it still have to agree with the invoice and the manifest data that came from the waybill. Read our guide to the air freight documentation checklist for the papers that must still be prepared by people rather than by systems.
It is also worth knowing that an e-AWB does not remove the need for the commercial invoice and packing list to accompany or precede the shipment in some form. A waybill describes the carriage; it does not replace the trade documents.
Where e-AWB goes wrong
Electronic does not mean error-proof. The most common failures are worth knowing before you experience one.
- Data entered once, wrong everywhere. A wrong weight or piece count in the forwarder’s system flows into the airline’s record and then into the manifest. Fixing it later takes an amendment message, and airlines commonly charge an administrative fee for changes. Ask your forwarder what their process and fee are.
- Paper-only stations. Not every origin or destination station handles every shipment electronically. If a route is not e-AWB capable, or the shipper has no agreement with that airline, the shipment reverts to a paper waybill. Confirm this when you book rather than when the cargo is at the airport.
- Mismatch between the two waybills. The house waybill and the master waybill should agree on the number of pieces and the weight. When a consolidator combines many shippers on one master, disagreements can appear, and the destination cargo terminal may hold your cartons until they are reconciled.
- Dangerous goods and special cargo. Items such as lithium batteries need additional declarations that the waybill data alone does not satisfy. See our article on lithium batteries in air freight.
A step-by-step look at one shipment
Imagine a Dhaka importer buying electronic modules from a supplier in Shenzhen. The supplier calls its forwarder, who books space on a flight and enters the shipment details into its system. The forwarder creates the house waybill, and the airline (or its handling agent) creates or accepts the master waybill. When the cargo is delivered to the origin warehouse, it is weighed, measured and checked against the data. Any difference between the declared weight and the measured weight is corrected at this point, before the flight.
On departure, the airline transmits status messages that the forwarder passes to the importer as tracking updates. While the aircraft is airborne, the manifest data is already available to the destination airport’s systems. On arrival the cargo is unloaded, taken to the cargo terminal and checked against the manifest. The importer’s clearing agent then presents the bill of entry together with the invoice, packing list, the air waybill data and any permits. We describe the destination-side steps in our guide to Dhaka airport cargo clearance.
At no point in this journey did an original waybill need to be posted, and that is precisely where the time saving comes from: the cargo is not waiting for a piece of paper that is still in a courier van.
Practical habits for importers
Ask the forwarder at booking whether the shipment will move as an e-AWB and, if not, why not. Request both the house and master numbers as soon as they are issued and check them on the airline’s tracking page. Compare the weight and piece count on the waybill against the packing list on the day it is issued, not on the day of arrival. And keep a saved copy of the waybill data with the rest of the import file, because Customs and your own accountant may ask for it long after the shipment has been delivered; our note on import record keeping explains why.
Finally, understand that chargeable weight is calculated from the waybill data and can differ from what you expected. If the invoice and the waybill disagree on weight, see chargeable weight explained before you dispute the charge.
What to do when the tracking page and the paperwork disagree
Sooner or later an importer meets a shipment where the airline’s status page shows fewer pieces than the packing list, or a weight that does not match the forwarder’s invoice. The instinct is to assume the airline has made an error. Usually the explanation is more mundane: a shipment split across two flights, a piece count that counts pallets rather than cartons, or a weight that has been rounded or re-measured at the origin warehouse.
The useful response is to ask the forwarder three specific questions. First, were the pieces booked on one flight or split? Second, was the cargo re-weighed or re-measured at origin, and does the waybill now show the revised figures? Third, do the house waybill and the master waybill show the same piece count? A forwarder who can answer these in one message is one who is tracking your cargo properly. One who cannot is a reason to reconsider whom you book with. If pieces genuinely arrive on different days, our article on split shipments in air freight explains how that affects charges and clearance.
Keep screenshots of the tracking page with a date and time whenever something looks wrong. Electronic records are overwritten as new status messages arrive, and a screenshot is often the only evidence of what the system showed on the day you noticed the problem.
The e-AWB is best understood as the same contract with a faster carrier: it saves time when the data is right and spreads mistakes quickly when it is wrong.
