At any time during the investigation and collection procedures, the messages "Investigation and Collection Information" (IE144) and "Request for Investigation and Collection Information" (IE145) may be sent to exchange additional information or ask questions about a specific shipment.

If additional documents need to be submitted in paper form, these may be sent by other means (fax, mail, email, etc.) directly to the contact person listed in the messages, clearly stating the MRN of the movement to which they correspond and, when sent in paper form, under form TC20 BIS (see the model in Annex VII.8.4).
