Best 3PL Warehouses in Seattle (2026)

The best 3PL warehouses in Seattle in 2026 are ShipCalm, Ryder, Smart Warehousing, Pacific Warehouse and Logistics, Shipazon, OLIMP Warehousing, Flowspace, and Long Road Warehouse. Most Seattle-area fulfillment happens in the Kent Valley and Sumner, between the Ports of Seattle and Tacoma. A warehouse there reaches Washington, Oregon, Idaho, Alaska, and British Columbia quickly, but sits in shipping zones 7 and 8 for most of the East Coast.

This guide is for DTC brands, importers, and omnichannel companies evaluating a Seattle-area fulfillment partner. Below are eight options for 2026 and what to check before you sign. See ShipCalm’s Seattle service area coverage for how we support brands shipping into and out of the Pacific Northwest.

Why Seattle Is a Strong Fulfillment Market

Seattle’s strength is its two ports and its position as the gateway to the Northwest, Alaska, and Canada. The main advantages:

• Two container ports: The Ports of Seattle and Tacoma operate together as the Northwest Seaport Alliance, giving importers a West Coast alternative to Los Angeles and Long Beach.
• Dense warehouse district: The Kent Valley and the Sumner area along Highway 167 hold one of the largest concentrations of industrial space on the West Coast.
• Regional reach: Ground shipments reach Portland in a few hours and Vancouver, BC and Boise within a day.
• Rail and air: BNSF and Union Pacific intermodal ramps and Sea-Tac Airport cargo operations sit close to the main warehouse areas.

The 8 Best 3PL Warehouses in Seattle

1. ShipCalm: Best Overall Seattle-Area 3PL

• Pros: Owns and operates warehouses in Southern California and Indianapolis, so Northwest brands can reach Midwest and East Coast customers far faster than from a single Seattle building. The Marvin AI platform shows inventory and orders across every channel. Native integrations with Shopify, Amazon, Walmart, WooCommerce, and SPS Commerce. Transparent pricing with a 90-day notice period.
• Cons: No facility in Washington, so Northwest customers typically see two- to three-day ground transit from Southern California.
• Pricing: Custom quote; see ShipCalm pricing details.
• Best for: Seattle-based brands whose customers are spread across the country and want one partner for DTC, Amazon, and retail orders.

2. Ryder

• Pros: Operates a 265,000-square-foot fulfillment center in Sumner between the Ports of Seattle and Tacoma, with transloading, pick and pack, kitting, and returns. The facility is a container freight station and designated foreign trade zone.
• Cons: Built for large national retailers and manufacturers, which may be more than a small brand needs.
• Pricing: Custom quote.
• Best for: Apparel, footwear, and home goods brands moving container volume through the Northwest ports.

3. Smart Warehousing

• Pros: Runs two Sumner buildings with 329,000 square feet of bulk and pallet storage, plus ecommerce, B2B, and retail fulfillment and transportation management. Part of a larger national network.
• Cons: Pallet and B2B capacity is the core strength, so very small DTC programs may not be a priority.
• Pricing: Custom quote.
• Best for: Brands that need both pallet storage and order fulfillment near the ports.

4. Pacific Warehouse and Logistics

• Pros: Family-owned public and contract warehouse in Kent, about six miles from Sea-Tac Airport, with easy access to I-5 and I-90. Experienced with U.S. and British Columbia distribution.
• Cons: Warehousing and distribution focus rather than high-volume DTC parcel fulfillment.
• Pricing: Custom quote.
• Best for: Brands selling into both the U.S. and Canadian markets from one Northwest location.

5. Shipazon

• Pros: Kent-based provider established in 2015 offering ecommerce fulfillment, Amazon replenishment, port drayage, transloading, cross-docking, and final-mile delivery.
• Cons: Smaller operation than the national providers on this list.
• Pricing: Custom quote.
• Best for: Amazon sellers importing through Seattle and Tacoma who want drayage and fulfillment from one provider.

6. OLIMP Warehousing

• Pros: On-demand warehousing in the Kent industrial corridor with port and rail drayage, container unloading, pallet rework, and cross-docking.
• Cons: Built for freight handling and overflow storage more than branded DTC fulfillment.
• Pricing: Custom quote.
• Best for: Importers needing short-term or emergency storage without long-term commitments.

7. Flowspace

• Pros: On-demand fulfillment network with warehouses in and around Kent, letting brands split inventory between Seattle and other U.S. locations.
• Cons: Partner-operated sites mean service can vary by location.
• Pricing: Custom quote.
• Best for: Brands testing a Northwest node as part of a distributed inventory strategy.

8. Long Road Warehouse

• Pros: Fife-based warehousing and distribution company offering fulfillment, trucking, ocean freight coordination, and supply chain consulting.
• Cons: Smaller team, so brands with large seasonal spikes should confirm labor capacity.
• Pricing: Custom quote.
• Best for: Importers near the Port of Tacoma who want freight and fulfillment handled together.

How to Choose a 3PL in Seattle

Seattle is fast for the Northwest and slow for everywhere else, so start with where your customers live. Check these four things:

1. Customer location: If most orders ship east of the Rockies, a Seattle-only warehouse puts many customers in zones 7 and 8. A multi-node setup like ShipCalm’s Southern California and Indianapolis facilities shortens transit for national brands.
2. Port strategy: Ask whether the provider handles drayage and transloading from Seattle and Tacoma, or whether you’ll need a separate freight partner.
3. Canada and Alaska: If you sell into British Columbia or Alaska, confirm cross-border and Alaska shipping experience.
4. Channel integrations: Confirm the warehouse management system supports every channel you sell on and plan to add.
