Worth knowing in Seattle-Tacoma
Aerospace and its suppliers around Everett and Renton need large, carefully specified boxes for parts that must not be scratched or bent. E-commerce operations in the Kent Valley and DuPont ship huge parcel volumes. Seafood processors on the waterfront need wet-strength cases. Year-round damp makes dry storage important for all of them.
Bellevue and Redmond software firms ship little by box, but the region's coffee roasters ship whole beans in cases and bags daily.
The Northwest Seaport Alliance runs the container terminals of both Seattle and Tacoma, and the Kent Valley between them holds much of the region's warehousing, between the river, the rail lines and the freeway.
