Cadmium Thin Film Sensor
A ceramic substrate with a pre-deposited cadmium thin film, functioning as a gas or temperature sensor in industrial monitoring systems. It is classified as an article of cadmium under 8112.69.00 because the cadmium film is the essential element, and the product is a finished article of cadmium, not a raw material.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the sensor is used for gas analysis and presented with its measuring apparatus
Instruments for physical or chemical analysis, including gas sensors, may be classified in Chapter 90 when they form part of a complete analytical system.
If the sensor operates as a variable resistor or thermistor
Electrical resistors, including thermistors, are classified in Chapter 85, which may apply if the cadmium film functions primarily as a resistive element.

Import Tips & Compliance
• Provide technical documentation showing the sensor's function and the role of cadmium, as this helps distinguish it from electronic instruments in Chapter 85
• Verify if the sensor meets Canadian electrical safety standards, which may require certification
• Declare the sensor's end-use to avoid misclassification as a general electronic component
