Tungsten Thermocouple Wire
Tungsten-rhenium alloy wire used in Type C thermocouples for high-temperature measurement up to 2300°C. Though alloyed, if tungsten-dominant (>99% per note exclusion), it fits HTS 8101.96.00.00 as tungsten wire.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If assembled into complete thermocouple sensor
Finished thermocouple assemblies classify as temperature sensors in Chapter 90, not raw wire.
If tungsten content <99% by weight
Per Chapter 81 note, low-tungsten alloys classify as 'other articles' excluding dominant base metal.
If sold as stranded wire rope
Stranded or twisted tungsten wire may be considered wire rope under Chapter 73, regardless of material.

Import Tips & Compliance
• Submit chemical analysis certificates proving tungsten content to avoid reclassification as 'other alloys'
• Differentiate from finished thermocouples, which may fall under 9025.19 if assembled
• Watch for strand count; multi-strand may classify as 'cable' under different provisions
