Since the late 1800s, IWLA has been serving warehouse logistics organizations. The American Warehousemen’s Association, founded late in the 19th century, represented warehouse operators’ interests primarily in their work with railroads. AWA was a founding member of the U.S. Chamber of Commerce. As warehouse logistics matured, so did the association, becoming the American Warehouse Association and then the International Warehouse Logistics Association. IWLA is a result of the 1997 merger between the then nearly 80-year-old Canadian Association of Warehousing and Distribution Services (CAWDS) with the American Warehouse Association (AWA). IWLA headquarters has always been in the Chicago area, now in Des Plaines, Ill.
IWLA member companies range in size from 10,000-square-foot, single-city warehouses to international companies with more than 25 million square feet of warehouse space. Most member companies primarily conduct business in North America.
