What the data is and is not

Transit days are port to port and come from published carrier services; they exclude U.S. trucking, waiting for a sailing and customs at destination.
A lane in the file means we publish and quote it; it is not a guarantee of space on a given sailing.
The files carry no prices. Indicative rates are in the separate rates CSV and are not a quote.
The version is the month the ports were last reviewed. File names include it, so older downloads stay distinguishable.
