In the intricate world of manufacturing, there exists a complex web of suppliers that contribute to the production of a final product. These suppliers are often categorized into different tiers based on their level of involvement and importance. In this post, we will dive into the differences between OEMs (Original Equipment Manufacturers) and supplier tiers 1, 2, and 3. Understanding these distinctions is vital for anyone seeking insights into the dynamics of the supply chain.

OEMs: The Foundation of Manufacturing

At the apex of the supplier pyramid are the OEMs, the companies responsible for designing and manufacturing a final product. OEMs have the primary role of conceptualizing, engineering, and assembling the end product. They possess extensive technical expertise and manage the integration of various components and subsystems. Major OEMs are household names, such as Apple, General Motors, and Boeing, whose products often require a vast network of suppliers across multiple tiers.

Tier 1 Suppliers: The Key Collaborators

Tier 1 suppliers are the close collaborators of OEMs, playing a crucial role in the supply chain. They are directly contracted by the OEMs to deliver subsystems or major components that are integrated into the final product. Tier 1 suppliers are usually specialists in their respective fields, providing specific expertise and advanced technologies. They possess a deep understanding of the OEM's requirements, and their performance directly impacts the quality, cost, and timeliness of the end product.

Tier 1 suppliers often have long-term contracts with OEMs and are involved in the product development stage. They have a significant influence on design decisions and work closely with the OEM's engineering team. Examples of tier 1 suppliers include companies like Bosch, Delphi Technologies, and Panasonic, which provide critical components like engines, electronic systems, and batteries.

Tier 2 Suppliers: Specialized Component Manufacturers

Tier 2 suppliers are one step further from the OEM and primarily focus on manufacturing specialized components or subsystems. They supply their products to tier 1 suppliers or directly to the OEM, depending on the arrangement. Tier 2 suppliers are more numerous and varied compared to their tier 1 counterparts, covering a wide range of industries and products.

These suppliers often specialize in a specific manufacturing process or technology. For instance, a tier 2 supplier may specialize in producing high-precision gears, molded plastics, or custom circuit boards. Their expertise and efficiency contribute to the overall quality and functionality of the final product. However, tier 2 suppliers typically have less direct involvement in the product development process than tier 1 suppliers. 

Tier 3 Suppliers: Raw Material and Basic Component Providers

At the base of the supplier pyramid are tier 3 suppliers, who are primarily responsible for providing raw materials, basic components, and commodities. These suppliers often deliver standardized items that are used in the manufacturing process, such as metals, plastics, fasteners, and other raw materials.

While tier 3 suppliers may not have a direct relationship with the OEM, their role is indispensable. They ensure a steady supply of essential components and materials necessary for the functioning of the entire supply chain. Tier 3 suppliers are usually numerous and compete on factors such as price, quality, and reliability.

Importance of Understanding Supplier Tiers

In the intricate pyramid of modern manufacturing, understanding the differences between OEMs and the various supplier tiers is crucial. OEMs are the driving force behind the product, while tier 1 suppliers collaborate closely to deliver critical subsystems. Tier 2 suppliers bring specialized components and expertise; tier 3 suppliers provide essential raw materials and basic components. Each tier plays a vital role in the supply chain, and their collaboration and performance directly impact the quality, cost, and timeliness of the final product.

As the manufacturing landscape continues to evolve, the boundaries between these tiers can become more fluid. Some tier 1 suppliers may also act as OEMs for certain subsystems or collaborate with tier 2 suppliers to offer more comprehensive solutions. Likewise, tier 2 suppliers may expand their capabilities to provide value-added services traditionally associated with tier 1 suppliers.

How Businesses can Benefit from Insights into their Supplier Tiers?

Understanding supplier tiering can help businesses identify potential operational, legal, and financial risks to which they may be subject due to suppliers in their supply chains.

Tier 1 suppliers often receive the greatest attention from businesses because of their tight relationship with them. Getting information about suppliers further up the value chain of a company can be more difficult. However, expanding supplier awareness past tier 1 suppliers may have benefits.

The following are a few ways that organizations might benefit from learning more about suppliers other than their tier 1 suppliers:

• Improving overall quality management and operational efficiency by increasing visibility into suppliers and their processes.

• Getting ahead of challenges related to sustainability, ethics, and safety in their supply chain, such as potential unfair labor practices, environmental degradation, or data security risks with lower-tiered suppliers.

• Improving supply chain traceability to understand where and how resources and goods are sourced.

• Increasing transparency for stakeholders interested in a company's long-term viability.

Conclusion

 By understanding the roles and distinctions between OEMs and the various supplier tiers, manufacturers can build robust and efficient supply chains. They can identify potential risks and dependencies, nurture strategic partnerships, and drive innovation throughout the process.

The supplier tiers in the manufacturing industry form a hierarchical structure, with OEMs (or tier 0) at the top, followed by tier 1, 2, and 3 suppliers. Each tier contributes its unique expertise, capabilities, and resources to ensure the successful production of the final product. The collaboration and coordination between these tiers are essential for the smooth functioning of the supply chain and the delivery of high-quality products to the market.
