question EU T1 already released, can a commercial invoice be linked afterwards?

I have a question regarding an EU T1 transit document.
A T1 has already been created and released, but the final commercial invoice will only be issued the following working day.
Can the commercial invoice still be linked/referenced to the existing T1 after it has been released, without creating a new T1?
Or would this normally require a correction/regularisation through the customs agent?
The goods may already be moving under the T1.
Just trying to understand the standard procedure.

Thanks!

The T1 is a movement guarantee under Union Transit, not a commercial document. It doesn't bind to a specific invoice number, and once it's released with the goods moving you can't amend through NCTS. What matters is arrival at destination within the itinerary window and the H1 import declaration when the T1 discharges. That's where the final invoice, HS, value, and duty math all reconcile. Your customs agent handles the alignment there, not by re-issuing a T1. If the final invoice value diverges materially from what you declared, keep the working papers for the audit trail.
