If you are returning goods to the supplier from whom you have imported them, enter a negative quantity on the receipt line in Isah.

If a customer you have exported goods to returns these goods to you, you register this return by entering a negative quantity on the shipping note.

Isah will process the negative quantities in your Intrastat declaration. There are two possible scenarios:

1. You always submit import and export declarations. In this case, Isah will put the return shipments in the opposite flow (an imported shipment you are returning will end up in the export flow), using transaction code 2.
2. You always submit either an import declaration or an export declaration. In this case, Isah registers the return shipment in the flow from which you are submitting the declaration, assigns it the commodity code 99600000, and adds an empty transaction code.
