Customs declaration is a document that must be provided by the customer to the Customs Administration of the Czech Republic when ordering goods from outside of the EU. Customs declaration can be submitted before the physical arrival of the parcel to Czechia, as soon as the recipient knows the tracking number of the parcel. In some cases, the end customer doesn’t need to submit the customs declaration because it’s taken care of by the online shop or the transport company. Zásilkovna helps online shops with customs declarations so that neither they nor the recipients have to worry about it. All you have to do is request an EORI number.
