You pay duty, THEN VAT on the value of the item (with the duty added). The handling fee is not for the delivery of the package as that had been paid for, but for handling the customs charges on your behalf, as it is the importer's (the recipient's) job to handle this.
With the proper paperwork, you can temporarily import or export goods without charges, like for repairs or, in your case, honing a razor. But that's admittedly rather tedious given the low value of the goods.
