This shipment contains [number] pieces: [package IDs] have been accepted, [package IDs] are proposed for refusal, and [package IDs or none] remain unconfirmed. Do you permit piece-by-piece handling, and whose confirmation is needed? If permitted, how will the return record list only the package IDs confirmed for return, how will delivery records for accepted pieces be retained, and who checks that the entire shipment is not mistakenly returned? If this is not permitted, please first explain the available options. This is an enquiry only; return transport has not been arranged.
