"THIS IS NOT A VALID IGM" on a Bill of Entry: what it means, and the IGM number to quote

In this film

• What the error says: at that customs station there is no Import General Manifest line matching what the Bill of Entry quotes — a statement about the IGM, not about your CSN
• Two enquiries over two databases: the older one reads the IGM, the new one reads the SCMTR filings. In the new one and not the old one means: accepted, and no IGM line yet
• Look the master bill up and read what the Bill of Entry quotes: the rotation (the IGM number) and the IGM line and sub-line — on the house line
• A transhipment (TC) house bill never gets an IGM line: nothing is missing, it moves on under transhipment
• Not the CSN number, not the CIN, not the ICEGATE id — each of those in the IGM field gives the same refusal

• "This is not a valid IGM"Why a Bill of Entry can be refused as “not a valid IGM” while your CSN was accepted — the IGM is raised at arrival — and what to do until then.
• Where is my cargo?Three questions that sound like one: did customs accept your filing, has the carrier filed their manifest, and where is the cargo now?
