What Are Supply Tiers?
Tier 1
Direct Suppliers to OEMs. These companies assemble and provide major components or systems (like a car's seating system or an electronic mainboard) directly to the final Original Equipment Manufacturer (OEM) like Samsung or Vinfast.
Tier 2
Suppliers to Tier 1. These firms manufacture the individual parts and sub-components that Tier 1 suppliers use in their assemblies. Examples include fabric for car seats or individual microchips for a mainboard.
Tier 3
Suppliers to Tier 2. Typically, these are processors of raw materials. This includes farms growing cotton, foundries casting metal, or processors of silicon for microchips.
The Vietnamese Context: A Dual Landscape
In Vietnam's high-value industries, the supplier landscape is heavily influenced by Foreign-Direct Investment (FDI), which dominates the high-tech Tier 1 positions. Local Vietnamese companies predominantly operate at the Tier 2 and Tier 3 levels.
Tier 1 Composition (High-Value Industries)
Illustrative breakdown showing the dominance of foreign-invested firms in top-tier supply roles.
Technological Capability by Tier
Tier 1 suppliers possess advanced, integrated technology, while local Tier 2 and 3 firms often specialize in single, lower-complexity processes.
Electronics Supply Chain (e.g., Samsung, LG)
The electronics sector is dominated by FDI giants. Local Vietnamese firms primarily feed into the supply chain at the component and raw material level.
Electronics Supply Chain Flow
Automotive Supply Chain (e.g., Vinfast, Toyota)
Similar to electronics, the automotive sector relies on high-tech Tier 1 FDI suppliers for critical systems, while local firms supply more basic processed parts.

Garment & Textile Supply Chain
In the garment industry, the roles are more integrated. A Tier 1 factory assembles the final product, relying on Tier 2 mills for fabric and Tier 3 for raw fibers.

Key Challenges & Dynamics
The primary challenge for Vietnam is bridging the "capability gap" to help its domestic SMEs move up the value chain from Tier 2/3 suppliers to high-value Tier 1 partners.
Challenge: FDI Dominance
While FDI creates a massive export industry, high-value componentry is often imported, limiting value captured by local firms.
Case Study: Samsung's Vietnamese Suppliers
Data shows that while many local firms are in the supply chain, very few have reached the critical Tier 1 status.
