September 29th is rapidly approaching. As mentioned previously in this blog, after that date, ACE will be the only approved EDI for transitioning required advance rail and sea cargo information and ABI in-bond transactions to US Customs. At that time, CBP will begin to decommission AMS for this functionality.
Most ocean and rail carriers and ABI in-bond filers have migrated to ACE. If you have not, CBP urges you to meet with your Client representative to establish a migration date prior to September 29th.
