ETD (Estimated Time of Departure) and ETA (Estimated Time of Arrival) are the estimated sailing and arrival dates of your shipment. The word that matters is “estimated”: they are the best available projection, not a contractual commitment from the carrier.
How to read them
The ETD depends on your cargo meeting the terminal cut-offs, documentary and physical, and on the vessel sailing on schedule. The ETA absorbs everything that happens on the way: weather, port congestion, transshipments, route restrictions. A good forwarder updates these dates during transit and tells you when they move, which is a large part of what tracking is worth.
Why they matter when importing from China
Every promise you make downstream rests on them: your launch date, your customer commitment, your campaign window. And between the ETA and your warehouse there is still discharge, clearance and last mile, where any hold-up adds demurrage.
The common mistake
Planning against the ETA as if it were a firm date, with no buffer. The sound practice is to commit dates to your customers with margin over the ETA, especially in peak season, and to monitor the shipment so you learn about slippage when it happens, not when it hurts.
