How do I send it?

The letters can have their postage paid using any stamps. Stamps with no denomination have the same value as the price of a 50-gram domestic letter. You can buy stamps from our service points or order via our shop. Such letters are marked by affixing a blue label to the left of the stamps stating Prioritaire/1:a-klassbrev or simply Prioritaire.

You post the letter in a PostNord mailbox or hand it in at a service point.

How much does it cost?

The price varies depending on the size of the letter. The current prices, stated in Swedish kronor (SEK) are as follows:

Can I send anything I want?

You can essentially send whatever you want, if it complies with the following restrictions:

In the case of air transport

Pursuant to the 2010 EU Directive, shipments transported by air have to be X-rayed to comply with air safety rules. If the X-ray does not provide any information about the contents of the shipment, the shipment will be sent using a different mode of transport, such as a rail or road. If that is not possible, the shipment is returned to the sender.

Sending shipments outside the EU

When sending products to destinations outside the EU, you must enclose special customs documents with your shipment. More information about customs procedures outside the EU.

Sending shipments within the EU

When sending goods within the EU, you always need to include a safety declaration (pdf).
