Products classified under HTS 8109.91.00.00
Zirconium Getter Alloy Strip
Getter strips of low-hafnium zirconium alloy for vacuum tube purification. Under 8109.91.00.00 for hafnium-compliant specialty strips.
Medical Grade Zirconium Rod
Solid rods of low-hafnium zirconium for surgical implants and instruments. HTS 8109.91.00.00 for biocompatible zirconium articles.
Zirconium 705 Powder (Atomized)
Gas-atomized zirconium 705 powder with <1:500 hafnium for additive manufacturing. 8109.91.00.00 covers unwrought powder forms.
Zirconium Cladding Foil
Foil for explosive cladding on vessels, low hafnium grade. Under 8109.91.00.00.
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.
Zirconium Grade 705 Sheet
Thin zirconium sheets of grade 705 alloy featuring low hafnium content (<1:500 ratio), ideal for cladding in reactors and heat exchangers. Classified under 8109.91.00.00 as 'other' zirconium articles excluding waste/scrap, due to its specific purity for non-nuclear commercial use.
Zirconium R60702 Wire
Fine zirconium wire (R60702 grade) with hafnium below 1:500 threshold, used in welding electrodes and medical implants. This product is categorized under HTS 8109.91.00.00 for low-hafnium zirconium articles in wire form.
Zirconium Grade 704 Plate
Thick plates of zirconium grade 704 with controlled low hafnium (<1ppm equivalent), applied in sour gas environments. Falls under 8109.91.00.00 as non-nuclear zirconium plates/articles.
Low Hafnium Zirconium Foil
Ultra-thin zirconium foil (<0.15mm) meeting <1:500 hafnium spec for pharmaceutical vessel linings. Classified in HTS 8109.91.00.00 for specialty low-hafnium zirconium sheets/foil.
Zirconium 702 Seamless Tube
