Bimetallic Temperature Reactive Strip from China
A bimetallic temperature reactive strip, composed of two bonded metals with different thermal expansion coefficients, that bends mechanically in response to temperature changes. This strip is designed as a component for wirewound variable resistors (including rheostats and potentiometers) of tariff item 8533.40.00, where its temperature-sensitive mechanical action adjusts resistance. Its metallic construction and thermal reactivity qualify it under this tariff item for parts of ceramic or metallic materials.

Import Tips
• Ensure the strip is specifically designed for use with wirewound variable resistors of 8533.40.00; otherwise, it may be classified elsewhere
• Keep technical datasheets showing the bimetallic composition and thermal deflection characteristics for CBSA verification
• Declare the material composition (e.g
• invar-nickel) to support classification under metallic parts
