The Pacific Northwest is the densest commercial aerospace manufacturing cluster in North America. Boeing's Puget Sound complex employs roughly 98,000 people across Washington and is supported by an ecosystem of approximately 600 Tier 1 and Tier 2 suppliers. Final assembly happens at four primary sites: Boeing Everett (777, 767, 747-8, KC-46 Pegasus tanker — the world's largest building by volume), Boeing Renton (737 MAX, the only 737 production line on earth), Boeing Auburn (1.7 million square feet of machining and parts fabrication — the largest Boeing site outside final assembly), and Boeing Frederickson (composites center for 787 components, vertical stabilizers, and wing fixed leading edges).
Aerospace freight is dominated by exactly the equipment classes Evergreen Shippers brokers best: oversize and superload flatbed, step-deck, multi-axle RGN with jeep + booster, refrigerated reefer for carbon fiber prepreg, cleanroom-grade dry van for sensitive composite and electronics, and AOG (Aircraft On Ground) expedite. The Boeing Production System (Boeing's lean manufacturing derived from Toyota TPS) imposes four-hour JIT delivery windows on most inbound parts — production-line stoppage costs Boeing an estimated $1 million-plus per hour. Carrier reliability is non-negotiable.
Evergreen Shippers (FMCSA MC#896325) is the Spokane-anchored transportation broker that dispatches aerospace freight along the I-90 corridor. Spokane sits 280 miles from Boeing Renton and approximately 290 miles from Boeing Everett — a comfortable solo overnight or team-driver day. The Senior Aerospace facility in Spokane is part of the same Tier 1 supplier ecosystem we dispatch against. Oversize permits, flatbed, and step-deck / RGN / lowboy are core equipment capabilities directly applicable to aerospace work.
We are a transportation broker only. We do not take title to aerospace freight, do not hold an ITAR or EAR license, and do not act as a customs broker. When ITAR-controlled freight is involved, we source carriers with verified ITAR clearance; the shipper retains licensing and filing responsibility. FTZ #5 documentation awareness for Everett and Renton inbound is part of our dispatch protocol; the shipper or their customs broker handles FTZ filings.
Five Boeing primary sites plus the defense, space, and Tier 1 supplier overlay. Every site has its own freight rhythm and equipment-match profile.
The world's largest building by volume (~472 million cubic feet). Final assembly for the 777, 767, 747-8, and KC-46 Pegasus tanker. Receives international wide-body sub-assemblies via the Boeing 747 LCF ("Dreamlifter") aircraft for the 787 program. Inbound freight includes massive composite wing panels, titanium machined parts, engine cowls, and very large tooling fixtures.
The only 737 production line on earth. Stations 0-4, final body join, paint, delivery to Boeing Field. Throughput target post-MAX-crisis recovery has been ~38 aircraft per month. The Wichita-to-Renton dedicated BNSF rail lane (Spirit AeroSystems 737 fuselages) is the most recognizable surface aerospace lane in North America. Surrounding the rail spine: constant flatbed/dry-van support flow for jigs, tooling, and components.
1.7 million square feet of machining and parts fabrication — the largest Boeing site outside final assembly. Feeds Everett and Renton internally and ships to the global supplier base. Outbound freight runs heavy on titanium and aluminum machined components, large milled parts, and tooling for distribution to Tier 1/Tier 2 suppliers nationwide.
The composites manufacturing center supporting 787 fuselage components, wing fixed leading edges, and vertical stabilizers. Inbound freight includes carbon fiber prepreg (refrigerated reefer required) from Toray Composites, Hexcel, and Solvay/Cytec. Outbound: finished composite sub-assemblies bound for Everett final assembly via flatbed or step-deck depending on dimensions.
Machining and parts fabrication operations in Portland. Smaller than the Washington primary plants but a meaningful node in the PNW aerospace freight network. Inbound titanium and aluminum stock, outbound machined parts to Auburn, Renton, and Everett or directly to Tier 1 suppliers.
Boeing Defense, Space & Security (Apache modernization, F/A-18 Super Hornet, KC-46 conversion). Aerojet Rocketdyne (Redmond WA — rocket propulsion). Blue Origin (Kent WA — New Glenn, New Shepard, BE-4 engines for both Blue Origin and ULA Vulcan). Spirit AeroSystems, Triumph Group, Senior Aerospace (Spokane, Bellevue, Burlington WA), Esterline / TransDigm (Bellevue), Crane Aerospace & Electronics (Lynnwood). ITAR-controlled defense freight requires US-person carrier verification and secure-facility handling.
Direct equipment-to-freight-type mapping. Aerospace freight is heavily weighted toward Evergreen's strongest equipment classes.
For oversize fuselage sections, composite wing panels (often 100+ feet long), large tooling fixtures, and engine + cradle assemblies requiring low deck height plus axle-weight distribution. WSDOT, ODOT, ITD, MDT permits coordinated in-house.
For medium-size sub-assemblies, tooling, engine cowls, vertical stabilizers, and Tier 1 supplier parts moving between Auburn / Frederickson / Renton / Everett or out to the national supplier base. Step-deck for taller items requiring under-bridge clearance.
GE, Rolls-Royce, Pratt & Whitney, and CFM International aircraft engines move via covered flatbed with shock-absorbing cradles, often crated to maintain cleanliness. International moves use Antonov An-124 or 747F dedicated freighter.
Carbon fiber prepreg from Toray Composites (Tacoma / Frederickson), Hexcel, and Solvay/Cytec requires temperature-controlled transport. Pre-impregnated composite material has limited out-time at room temperature and must be cold-stored. Continuous-run reefer with temperature recording.
Clean, sealed trailers for sensitive composite layups, finished electronics, painted parts, and any aerospace cargo requiring dust-controlled handling. Trailer pre-clean and prior-load documentation verified before dispatch.
For Aircraft On Ground critical parts. Sprinter or cargo van for small high-value parts; hotshot for medium parts; air freight coordination through Boeing Field or Sea-Tac for very large or international moves. 24/7 expedited dispatch.
Boeing's lean manufacturing system — derived from Toyota Production System (TPS) — runs the inbound parts cadence at Renton and Everett. The discipline cuts both ways:
The freight implication: carrier vetting includes FMCSA authority, insurance certificates, safety scores, and prior aerospace experience. Real-time tracking is non-negotiable. Proactive exception communication (delay, equipment, weather) is the dispatch standard, not the exception.

Standard $100K carrier cargo coverage is inadequate for most aerospace dispatches. We supply $500K-$1M+ additional cargo limit endorsements as required.
Federal Aviation Administration governs Parts Manufacturer Approval and Technical Standard Order parts shipping. The shipper holds the FAA registration and quality system; Evergreen handles transportation.
Governs defense aerospace exports including KC-46 components, Apache modernization parts, and rocket propulsion. Requires US-person carrier drivers/operators, secure-facility handling, and prior defense aerospace experience. Evergreen sources carriers with verified ITAR clearance; the shipper holds the ITAR license and filing responsibility.
Governs dual-use parts (commercial-grade items with potential defense application). Different regulatory regime from ITAR but similar carrier-verification implications.
Boeing Everett and Renton are within FTZ #5. FTZ status enables duty-free entry for imported aerospace parts re-exported as finished aircraft. Evergreen is not a licensed customs broker — the shipper or their customs broker handles FTZ filings; we coordinate carrier paperwork, BOL flagging, and seal protocols against FTZ receiving docks.
Boeing Production System discipline. Parts can't arrive too early (no warehouse) or too late (line stops at $1M+/hour). Standard commodity dispatch fails this discipline routinely.
JIT window confirmed at dispatch and pickup. Real-time GPS tracking with exception alerts. Carrier vetting includes safety scores, prior aerospace experience, and driver tenure.
Carriers with cleanroom-grade trailers, shock-absorbing engine cradles, certified oversize/superload experience, or refrigerated prepreg capability are not commodity capacity. The pool is small.
Carrier rolodex weighted toward aerospace-experienced fleets. Multi-axle RGN with jeep + booster, cleanroom dry van, and refrigerated reefer with continuous-run pre-vetted before dispatch.
Aircraft engines run $5M to $30M each. Composite wing panels $500K to $5M. Standard $100K carrier cargo limits inadequate by orders of magnitude.
Additional cargo limit endorsements supplied as required by the shipper, Boeing Supplier Portal, or prime contractor. Carrier cargo coverage verified per load.
KC-46 components, Apache modernization, rocket propulsion. Requires US-person driver/operator verification and secure-facility handling. Random commodity carriers don't qualify.
Carriers with verified ITAR clearance dispatched on defense aerospace work. Shipper retains licensing and filing responsibility; Evergreen handles transportation execution.
Aircraft On Ground events cost airlines tens of thousands of dollars per hour. Standard commodity dispatch can't field a Sprinter at 3 AM Sunday morning.
After-hours AOG dispatch capability. Sprinter, cargo van, hotshot, or air freight coordination through Boeing Field / Sea-Tac. Driver availability verified, load stayed on through delivery.
Boeing Everett and Renton are within FTZ #5. Inbound customs paperwork differs for FTZ-destined freight versus standard domestic entry. BOL flagging and seal protocols matter.
Carrier paperwork, BOL flagging, and seal protocols aligned against FTZ status. Shipper or their customs broker handles FTZ filings; Evergreen handles transportation execution.
