ONE and MSC Strengthen SX1: China-East Coast South America
ONE and MSC strengthen SX1
ONE (Ocean Network Express) has announced an operational update to its South America East Coast Express 1 service, known as SX1. From April 2027, ONE and MSC will jointly operate the service on a weekly fixed-day schedule.
The carriers say the revised arrangement is intended to improve schedule reliability and transit times. It also maintains direct coverage between major Asian load ports and key ports on South America's east coast.
Chrislion Logistics (CSL) can quote and book cargo on SX1. Our participation covers the commercial booking and the shipment coordination around it: we match the service to your cargo and delivery window, confirm the live sailing and cutoff with the carrier, and coordinate the documentation and delivery steps around the ocean leg.

ONE and MSC operate the ships. Chrislion Logistics is the freight-forwarding partner that connects your shipment to SX1. We quote the service against your cargo details, ready date and final address. We also compare another ocean service, LCL consolidation or air freight when a different option fits the shipment better.
- Booking and space. Chrislion requests the booking from the carrier, confirms the vessel and terminal, and checks the documentation cutoff before cargo moves.
- Schedule verification. We compare the published SX1 rotation with the live sailing schedule. If a port call or cutoff changes, we tell you before the shipment is committed.
- Document and customs coordination. Chrislion coordinates the export documents, customs steps and destination requirements with the parties involved in the shipment.
- End-to-end shipment management. From the origin pickup to the destination delivery, CSL stays in contact with the shipper and coordinates the stages around the ocean leg.
