Tungsten Thermocouple Wire from China

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
