Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not photosensitive but other semiconductor types
Non-photosensitive transistors like power or RF types go to 8541.48, distinct from photosensitive under 8541.49.
If imported as part of an electrical apparatus set
When imported as assembled parts of larger machines, they may fall under 8543 for electrical machinery parts.

Import Tips & Compliance
• Declare material composition (e.g
• GaAs) accurately as it affects duty rates and REACH compliance
• Use cleanroom shipping protocols to avoid contamination, which can lead to customs holds
• Verify export licenses from origin country for dual-use semiconductor tech
