Common paperwork mistakes with heading 2923
- The invoice shows the exporter's own code. Only the first six digits are shared worldwide; the US number has ten. Check every line against the list above.
- The quantity is in the wrong unit. These lines report quantity in kg, which may not match the invoice's cartons, sets or pieces.
- The packing list and the bill of lading disagree on cartons or gross weight, which can lead to holds and exams.
- The manufacturer's name and address are missing, so the MID cannot be built from the documents.
Look up any ten-digit number, or read the guide to invoice and packing list mismatches.
Check the whole shipment, not one number
