Can the freight forwarder transmit supplementary cargo reports before the marine carrier transmits the primary cargo report?
A 4. Yes. There are no rules respecting the order in which electronic cargo data is received. For example, the freight forwarder may transmit their supplementary cargo reports before the marine carrier transmits their primary cargo report and vice versa. The reports are linked in the Customs system by the carriers’s Cargo Control Number (CCN), which the freight forwarder will quote on their supplementary reports.
