Rail carriers must electronically transmit advance cargo information for trains with commercial cargo, including through and in-bond cargo, no later than two hours before the cargo reaches the first US port of arrival. For trucks, CBP must receive the cargo information through a CBP-approved EDI system no later than 30 minutes or one hour before arrival, depending on the system used; domestic cargo transiting Canada or Mexico and certain low-value informal entries are exempt. Carriers must obtain the shipment information from shippers or forwarders before accepting cargo.
