U.S. Customs and Border Protection will require that trucks entering the U.S. through border ports in Maine and Minnesota transmit electronic manifests through the Automated Commercial Environment (ACE) program. The ruling is set to take effect on Oct. 16. Currently, the filing of ACE e-manifests is required at land border ports on the U.S. Mexico border and in the states of Washington, North Dakota, Michigan, New York, Vermont and Hampshire. The system allows Customs to pre-screen trucks and shipments, flagging suspicious cargoes for inspection before they arrive. Previously, truck drivers have presented paper manifests upon arrival at a border; the documents were then processed while the driver waited. With the addition of Maine and Minnesota, Customs said it has now required the use of ACE for transmission of electronic manifest data, or provided 90 days' notice of its intention to do so, at every land border port in which the agency originally planned to require the use of ACE, with the exception of those in the state of Alaska. Eventually, the agency said, the transmission of e-manifests through ACE will be required at all land border ports of entry to the U.S.
