When Should I Ship by Ocean?

Ocean freight is transported by ship, in large containers. It is the slowest, but most affordable freight option. In addition to traditional ocean passage, water carriage also includes inland and inter-coastal waterways, such as rivers, canals and lakes.

Schedule a Pickup

If you’re scheduling your own pick-up, it’s a good idea to book the pickup several days in advance of your needed pickup date. Determine if you or your recipient will require a liftgate, in the event either of you don’t have a loading dock. Contact the carrier’s local service center. If you’re using UPS, you can schedule your pick up through the UPS Forwarding Hub, where you’ll also receive your cost estimate and tracking number.

Transport Your Shipment

Your shipment is transported to the nearest port and loaded on an ocean vessel. If you have a tracking number, you can keep track of your shipment, or if available, be alerted at key milestones or if any exceptions occur.

Clearing Customs

When your shipment arrives at its destination air gateway, it is processed for Customs clearance, which can take up to three days. If the shipment clears Customs before 9 a.m. that day, it can be loaded onto a truck to be driven to its final delivery destination. Your shipment only has to clear customs in the country of its final destination. UPS has over 100 years of customs brokerage experience. If you have any questions or would like UPS to broker your cross-border shipments, you can speak with one of our experts.
