Import from China to Washington
Washington State is the Pacific Northwest's gateway to Asia. The ports of Seattle and Tacoma (operating jointly as the NWSA) are geographically the closest major US continental ports to China. This translates to incredibly fast ocean transit times. It is heavily utilized by massive local corporate headquarters and as a fast rail-link inland to Chicago and the Midwest.
Due to the curvature of the earth (Great Circle Route), ships traveling from Northern China, Japan, or Korea to Seattle have shorter distances than those traveling to Los Angeles.

How to use this Washington import guide
Washington guides provide tactical route planning for importers shipping from China. This page brings those pieces together for importers evaluating shipments into Washington. It highlights local infrastructure, the products and industries most exposed to China sourcing, and the US-specific cost logic that matters once Section 301 tariffs, MPF, and HMF are factored in.
The most important local question is not just whether goods can reach Washington, but how they reach it most efficiently. In practice, that means matching the shipment to 3 major port or ICD options, the buyer's warehouse location, the urgency of the inventory, and the product class being imported. A route that looks cheap at the port level can become slower or more expensive after rail movement, ICD handling, or inland delivery.
For importers in or around Washington, the industries that usually shape demand are Aerospace, Technology, Agriculture, E-commerce, Timber. The corresponding China-sourced categories often include Aerospace components, Consumer electronics, Sporting goods, Apparel, Machinery.
