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

We invite you to learn more about WTSA, its members and its activities. This site also provides updated information on voluntary, non-binding guidelines adopted by WTSA which may affect rates, charges and service terms offered by individual WTSA carriers.
