Indium-Tin Amalgam
Indium-tin amalgam is a liquid metal alloy used as a thermal expansion liquid in thermometers, consisting of indium and tin. It is classified under tariff item 2853.90.00 as an amalgam other than of precious metals, as it contains no mercury or precious metals. The product's use in thermometers does not affect its classification, as the heading covers all non-precious amalgams.

Import Tips & Compliance
• Confirm the alloy composition to ensure it is an amalgam and not a simple alloy, which would be classified elsewhere
• Declare the product as a non-precious amalgam under tariff item 2853.90.00 and be prepared to provide composition data to the CBSA
• If the thermometer is imported as a finished product, it may fall under a different heading (e.g
• 9025.11.00)

2-inch Undoped Gallium Arsenide Test Wafer
A 2-inch undoped gallium arsenide test wafer is used for process control and calibration in semiconductor fabrication. Chapter Note 8 to Chapter 28 states that chemical elements doped for electronics are classified in this chapter only in unworked forms; however, gallium arsenide is a compound, not an element. Undoped wafers cut into discs or wafers fall under heading 3818, not this tariff item.
