After translating it says the status of the package has left customs and is waiting for users to pay taxes. Do I have to do that? If so, where and how?

Thanks

I have sent a parcel back to a supplier for a refund and the tracking is currently saying it is in customs waiting for users to pay taxes. If they company i am returning the package to don't pay this, will the parcel be retuned to me? If so, when?

Thanks

My package with nr. RT128961377NL is in transit for a few days now waiting for users to pay taxes. It is a return package so why does it need to get pay taxes?
