The Motor & Equipment Manufacturers Association (MEMA) was founded in 1904. MEMA represents more than 1,000 companies that manufacture motor vehicle components and systems for the original equipment and aftermarket segments of the light vehicle and heavy-duty motor vehicle manufacturing industry in the United States. MEMA works at state, federal, and international levels to ensure that the marketplace and public policies support the development of advanced, transformative technologies that enable safer, smarter, and more efficient vehicles. Motor vehicle parts manufacturers are the nation’s largest manufacturing sector, directly employing more than 871,000 U.S. workers. Motor vehicle component manufacturers are the largest employer of manufacturing jobs in the U.S., contributing nearly 3 percent of the U.S. gross domestic product. Motor vehicle parts suppliers generate a total direct and indirect employment impact of 4.26 million jobs, up nearly 18 percent since 2012.[1]

MEMA is the parent organization of four affiliate associations: AASA, HDMA, MERA, and OESA.[2]

The motor vehicle component manufacturing industry in the U.S. has experienced robust growth due to increased demand and vehicle sales. The stability and highly integrated North American supply chain has also been particularly beneficial to suppliers, contributing to growth in both jobs and investments in the United States. Many suppliers located in the U.S. import and export vehicle parts and components within the North American market. Depending on supply chain logistics, parts are often exported to be combined with other parts, then imported back to the U.S. for final vehicle assembly.


Automotive Aftermarket Suppliers Association[edit]

U.S. aftermarket suppliers support the light-, medium- and heavy-duty vehicle markets. The aftermarket segment includes the manufacturing, distribution, retailing and installation of all vehicle parts, chemicals, tools, equipment and accessories. Most aftermarket repair work takes place in a vehicle manufacturer’s dealership service facility or an independent repair shop. There is also a strong “do-it-yourself” market – individuals who perform their own vehicle maintenance.[3]

Heavy Duty Manufacturers Association[edit]

Heavy-duty suppliers provide the original equipment parts used to manufacturer commercial vehicles and aftermarket replacement parts needed to maintain the vehicles in service and on the road. Heavy-duty suppliers are also responsible for developing most of the technologies that keep these vehicles safe.[4]

Motor & Equipment Remanufacturers Association[edit]

Through remanufacturing, products that are worn, imperfect or discarded are brought to a manufacturing environment where they are cleaned and checked. Reusable product parts are brought up to factory or performance specifications. Parts that cannot be reused are replaced.[5]

Remanufacturing preserves the value of the original manufacturing-including energy costs and waste disposal-which recycling alone cannot do.

Original Equipment Suppliers Association[edit]

Original Equipment (OE) Suppliers designed to procure and manufacture the components by the manufacturer required for vehicles. OE suppliers provide approximately 60 percent of the vehicle value through visible components such as stereo systems to components hopefully a customer will never see such as air bag modules.[6]

An automobile contains 8,000 to 12,000 components and OE suppliers provide the right part, at the right time, at the right assembly plant every day to support 75 million units of annual global vehicle production.

The OE supplier is the largest manufacturing sector in North America. As such, the sector is often divided into levels or tiers. Tier 1 suppliers provide full design and engineering support, Tier 2 suppliers manufacturer components to blueprint specifications, and Tier 3 suppliers provide raw materials, material fabrication and discrete parts.

While there are approximately 3,000 suppliers supporting the industry, it is more likely there are 500 core automotive suppliers that provide the majority of the value of the vehicle.
