Cupro-Nickel Thermocouple Wire Type T from Canada
This is a bare cupro-nickel wire used in Type T thermocouples for temperature measurement in industrial and laboratory settings. It falls under HTS 7408.22.50.00 as it is made from copper-nickel base alloys (with nickel predominating over other elements and zinc under 1%) and is not coated or plated with metal.

Import Tips
• Provide alloy composition certificates confirming nickel predominance and zinc <1% to verify copper-nickel base alloy status
• Ensure wire diameter and temper specs match statistical reporting requirements; uncoated status must be documented
• Avoid misclassification as nickel silver by testing for nickel content ≥5%; common pitfall is incorrect elemental analysis
