Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

8504.40.70Lower: 35% vs 50%

If made up into power supply modules

Assembled into static converters shifts to heading 8504 for electrical transformers and converters.

8541.29.00Same rate: 50%

If after dicing and mounting but before final encapsulation

Mounted but unencapsulated transistors fall under the general 'other transistors' subheading.

3920.99Lower: 15.8% vs 50%

If polymer substrate wafers mistaken for plastic articles

Silicon wafers are semiconductor devices, not plastics; material composition determines heading.
