Definition & Explanation

In freight operations and contract logistics, T-1 denotes the day immediately before a defined milestone – a vessel's cut-off, a customs examination, or a scheduled delivery window. All preparatory tasks should be completed by T-1: documents verified and submitted, transport orders confirmed, loading instructions issued. The notation is borrowed from project management and has become standard shorthand in sea freight tracking and operations planning. T-1 carries no customs significance whatsoever; it is a scheduling reference only, not to be confused with T-2, the EU customs procedure for proving the Union status of goods in transit.
