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.

Import Tips
• 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
