Question
If an NVOCC is both billing and billed party, was the additional dispute window provided after notice?
Required element
Additional 30 calendar days for the NVOCC to dispute.
Provision slug
cfr-541-7-c
Consequence if missing
Failure to provide the additional window undermines the Part 541 dispute process; the row is not itself a §541.5 invoice-field test.
