Cupro-Nickel Thermocouple Wire Type T from Mexico

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
