Discarded Rhenium Thermocouple Wire from China
Burnt-out thermocouple wires alloyed with tungsten-rhenium for high-temperature furnace monitoring, now as scrap. Under HTS 8112.41.10.00 as rhenium waste and scrap due to significant rhenium content for recovery. Common in semiconductor and glass manufacturing.

Import Tips
• Spectrographic analysis mandatory to quantify rhenium vs tungsten for correct Chapter 81 subheading
• Cut wires to <2m lengths for standard scrap baling and containerization
• Separate from Type C thermocouples (W5Re-W26Re) to avoid 8101 classification
