Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If marketed solely as a generic heat sink without diode integration
Standalone heat exchangers for electronics go to 8419.90, separate from converter-specific parts.
If diodes are primary and heat sink secondary
Diodes as semiconductor devices dominate classification under 8541 if not converter-dedicated.
If for transformer rather than static converter parts
Similar cooling assemblies for transformers are classified separately in 8504.90.75.
