Zirconium 702 Grade Bar Stock
High-purity zirconium bar stock made from grade 702 alloy with less than 1 part hafnium per 500 parts zirconium, used in chemical processing equipment. This falls under HTS 8109.91.00.00 due to its low hafnium content and unwrought form as bars suitable for further fabrication. It meets chapter definitions for zirconium articles excluding high-hafnium nuclear-grade material.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in tube or pipe form with attached fittings for gas/liquid conduction
Per US note, fitted tubes/pipes qualify for free duty under 8108.90.60 if suitable for fluids, shifting from general zirconium articles.
If considered unwrought ferro-zirconium for steelmaking
Ferro-zirconium alloys over 2% zirconium by weight fall under Chapter 72 iron/steel headings, not base metals.
If in powdered or granular form for nuclear applications
Zirconium compounds or nuclear-grade powders are classified under Chapter 28 chemicals, separate from metallic articles.
