Boeing 737: American Made But Globally Sourced
The Boeing 737 is often seen as a symbol of American aerospace excellence. But peel back the fuselage and you’ll discover a much more intricate story—one of international collaboration, supply chain complexity, and global interdependence.
The aircraft’s thousands of components are sourced from at least two dozen countries and multiple continents. While Boeing leads final assembly in the United States, the company relies on global partners to provide specialized parts ranging from titanium forgings in Italy to cabin seating in Japan.
This global sourcing strategy, visualized by Julie Peasley and based on data from Air Framer, demonstrates the immense complexity of modern aircraft manufacturing.
Here’s a breakdown of key parts in the Boeing 737 and their country of origin:
Country Aircraft component for Boeing 737 Australia Wing ailerons Austria Blended winglets and split winglets Belgium Engine compressors, oil tank, pump, filter, and valve Belgium Flap/slat mechanisms Canada Communication antennas Canada Airborne communication systems Canada Wing tip panels Canada Wheel well fairings Canada Aircraft doors Canada Cabin curtains Canada Power transmission torque tube drives Canada Inner barrel for engine nacelle inlet Canada Nose landing gear assemblies (titanium components) Canada Electromagnetic indicators and annunciators Canada Winglet and wing components China Forward entry door China Rudder China Flight deck panels China Carbon brake disks China Interior completion of cabin China Vertical fin China Aft fuselage section China Aircraft landing gear France Wing assembly France Bearings France Inflight entertainment France Engine electrical wire harnesses France Titianium/aluminum structural components France Piston rings France Thrust reversers France Autothrottle system France Electrical power contactor France Engine hydromechanical fuel pumps France Wheels France Emergency locator transmitter France Cockpit door surveillance cameras France Structural bulkhead France Standby flight display France Limit and proximity switches France Fasteners Germany Corrosion protecting coatings Germany Cabin exit signs Germany Passenger Seating Germany Cabin galley and stowage bins Germany Cargo sliding carpet system Germany Winglet lightning harness Germany Cabin pressure control system Germany Fuselage anti-collision lights Germany Door locks and latches Germany Ice protection equipment Germany Window seals Germany Forgings, castings and extrusions India Vertical fin structures India Wire harnesses India Strut assemblies Israel Cargo and passenger doors Israel Metal parts and structures Israel Wheel well panels Israel Aluminum and steel for winglet Italy Titanium forgings Italy Rotor blades and stator vane Japan Inboard flaps and flap segment Japan Passenger Seating Japan Lavatory equipment Latvia Arm caps for economy class seats Malaysia Airframe saddle fairing Morocco Wire harnesses Netherlands Galleys, closets, class dividers Netherlands Electrical wiring, wire harnesses, junction boxes Netherlands Laminates for various components Norway Turbine engine vanes and casings Russia Titanium South Africa Vacuum-formed cockpit and cabin assemblies South Africa Precision machined interior linings South Korea Lower door skin, inner skin cover detail South Korea Electronic equipment door South Korea Empennage (737 MAX) South Korea Interior bulkheads South Korea Flap support fairing and winglet South Korea Rear wing spar and jackscrew Spain Flight control surfaces Spain Rudder Spain Sheet metal bending and milling Sweden Engine gearbox bearings Sweden AC/humidity control Switzerland Airborne vibration monitor Taiwan Main landing gear door Taiwan Pressurized doors Taiwan Engine case Turkey Rear fuselage and tail surfaces Turkey Flight deck panels Turkey Wing tips Turkey Structural components Turkey Cabin cabinets Turkey Engine fan cowls UK Thrust reverser actuator UK Flight control actuators UK Blended winglets UK Wing flaps structural ribs and substructures UK Engine sensors, and monitoring UK Nacelle inlet lip skins UK Cockpit voice recorder and flight data recorder UK Extended range auxiliary fuel tank UK Cockpit indicators and switches UK Tires UK Electrical static dischargers UK Aircrew seats and gear drives UK Airborne communication antenna UK Emergency lighting floorpath system UK Flight deck entry video surveillance system UK Emergency locator beacon UK Jet engine rings UK Anti-spall windshields UK Packing and filling material Why Build a Jet Like This?
Commercial aircraft contain millions of precision parts, many made from exotic alloys or advanced composites. No single country holds all that know‑how. Russia’s VSMPO‑AVISMA, for instance, remains the world’s dominant source of aerospace‑grade titanium—a metal prized for its strength‑to‑weight ratio and corrosion resistance.
By tapping specialized suppliers, Boeing keeps costs competitive, earns reciprocal market access abroad, and balances political risk by spreading production across multiple jurisdictions.
Risks of Tariffs and Protectionism
However, this level of globalization exposes manufacturers to geopolitical and economic risks. According to Reuters, aerospace firms have lobbied hard to preserve tariff-free agreements between the U.S. and EU. Even temporary tariffs in past disputes have disrupted delivery schedules and increased costs.
Analysis from Harvard Business School points to rising protectionism as a major threat to supply chain stability. As governments reevaluate trade policies, the world’s major aircraft companies may be forced to rethink their international sourcing models—a costly and complex endeavor.
