WTSA - The Westbound Transpacific Stabilization Agreement

Welcome to the westbound web site of the Transpacific Stabilization Agreement (TSA). TSA is a research and discussion forum of container shipping lines operating in the trade lanes connecting the U.S. and Asia. Members provide scheduled ocean transportation and intermodal door-to-door logistics services, including service for refrigerated, hazardous, oversize project and other specialized cargoes.>


This site provides information on TSA activities in the westbound market segment from the U.S. to Asia. For information on TSA as it relates to the eastbound Asia-U.S. segment, visit tsacarriers.org.

TSA’s voluntary, non-binding guidelines on pricing, terms of service and operations, and the channel of communication it maintains with customers, are intended as a stabilizing influence to maintain consistent, reliable and compensatory rates and service levels in the market.

New: With input from our westbound Shipper Advisory Board, TSA has developed a helpful checklist to aid U.S.-Asia shippers and carriers in the service contract process. The checklist is posted in the “Markets” section, under “Shipper Relations”.
