Alternative Classifications

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

8533.21.00Lower: 35% vs 38.5%

If used as general temperature sensing without motor protector specificity

General PTC thermistors not dedicated to 8536 apparatus fall under resistor headings

8536.50.90Lower: 35% vs 38.5%

If imported as complete assembled switch rather than discrete part

Complete temperature switches are classified in 8536, not parts heading 8538
