We use RM Click & Drop for all our sales. I understand this ensures that the up to date Amazon IOSS code is used.

I believed that the law ruling on customs charges identifies AMAZON as liable for collecting and paying the import duty (recovering the cost prior to funds disbursement to the market trader).

While this appears to work well for most of Europe with the Amazon IOSS code appearing on the CN22 lable correctly, La Post has recently been sending import charges to the recipients of our orders. Orders to other countries using the RM system appear to be unaffected.

If anyone could clarify what might be happening I would be grateful as our customers are quite rightly as puzzled as we are.
