What the message actually contains
An ASN describes the shipment in a nested hierarchy: the shipment, the pallets, the cartons inside them, and the items inside those. Each carton carries an SSCC — the barcode the retailer scans on arrival to match physical goods to your electronic message.
That structure is why the ASN is such good dispute evidence. It is a timestamped record of what you said you shipped, sent before anyone knew there would be an argument.
When it has to be sent
Almost every routing guide requires the ASN to be transmitted before the goods physically arrive — commonly at despatch, sometimes with a minimum lead time of an hour or more. Miss that and the receiving system has nothing to scan against, so the delivery is handled manually.
Why a late ASN becomes a chargeback
A missing or late ASN forces the retailer to receive goods by hand, which costs them time, so the penalty is automatic and flat — typically €25–500 per occurrence, sometimes per carton. It is one of the most common compliance deductions in fashion wholesale, and one of the most winnable: the transmission timestamp either proves you sent it in time or it does not.
If the retailer's system logged it late but your EDI provider logged it on time, the gap is usually theirs — a queue backlog on their side. That is a dispute you should win. See how to dispute retailer chargebacks.
ASN, DESADV and EDI 856 — the same thing
They are three names for one document. EDI 856 is the ANSI X12 version used in North America; DESADV is the UN/EDIFACT version used across Europe; ASN is what everyone calls it in conversation. If you sell into Zalando, Otto or Breuninger you are sending DESADV. See the DESADV message explained.
Frequently asked
What does ASN stand for in shipping?
ASN stands for advance shipping notice — an electronic message sent to the buyer before a delivery arrives, listing what is in the shipment and how it is packed, so the goods can be received by scanning rather than by hand.
Is an ASN the same as a DESADV?
Yes. DESADV is the UN/EDIFACT name used in Europe and EDI 856 is the ANSI X12 name used in North America. Both are advance shipping notices carrying the same information.
What happens if an ASN is late?
Most retailers raise an automatic compliance chargeback, typically €25–500 per occurrence. Because the charge rests on a transmission timestamp, it is one of the more winnable deductions when your EDI logs disagree with theirs.
