SENT XML generator: how to create SENT100, SENT200 and SENT300 files for PUESC
Published October 2026
If you move goods covered by the Polish SENT system, the notification has to reach the PUESC platform. Many companies type every field into a web form for every single shipment. A SENT XML generator does the same job differently: you fill in the data once, the generator checks it and produces a ready XML file that you upload to PUESC.
What a SENT XML file is
It is a structured file that contains the same information as the notification form: the parties (carrier, sender, recipient), the vehicle, the route with the border-crossing points, the document, and the list of goods with CN codes, quantities and units. The structure and formatting must follow what PUESC expects, which is exactly where manual work goes wrong.
What a good generator does for you
- Keeps every field in the correct format — postal codes in the XX-XXX form for Polish addresses, a period as the decimal separator, units of measure written the way PUESC expects.
- Remembers contacts and vehicles, so a repeat shipment takes a minute instead of ten.
- Covers all three forms — SENT100 (sender), SENT200 (recipient) and SENT300 (carrier). See the differences between them.
- Checks the data before it creates the file, so you find a missing field on your screen and not in a rejection.
- Keeps a library of earlier declarations that you can reopen, correct and generate again.
Step by step
- Choose the form that matches your role in this shipment.
- Pick the carrier, sender and recipient from your saved contacts, or enter them once.
- Add the vehicle, the route and the goods (CN code, name, quantity, unit).
- Generate the XML file.
- Upload it in PUESC and keep the confirmation. How that step works is described in our guide to uploading a SENT XML file to PUESC.
Before you submit
A generator formats your data; it does not know whether the data is true. You remain responsible for the content of every notification, and mistakes can have consequences (see SENT fines and penalties). Always compare the file with your transport documents.
