Sintered Tungsten Rod for Lamp Filaments from Germany
A high-purity tungsten rod produced by powder metallurgy sintering, used primarily in manufacturing incandescent and halogen lamp filaments. It qualifies under HTS 8101.94.00.00 as unwrought tungsten in rod form obtained simply by sintering, without further mechanical working. This form provides the necessary ductility and high melting point for filament applications.

Import Tips
• Verify purity certificates showing tungsten content to confirm classification under Chapter 81 and avoid reclassification as alloys
• Provide documentation proving the material is 'unwrought' and obtained simply by sintering, not involving drawing or forging
