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”.
