Zirconium Pigs Nuclear Grade
Cast zirconium pigs with hafnium <0.2% (1:500 ratio), weighing 25-50kg each, produced via Kroll process for remelting. Unwrought form under HTS 8109.21.00.00 due to low hafnium for reactor cladding. Primary material for fuel rods and control elements.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If waste, scrap, or remelt material not meeting purity specs
Zirconium waste/scrap regardless of hafnium content goes to 8109.90.
If ferro-zirconium alloy with >10% iron content
Ferro-alloys classified under Chapter 72 iron/steel.

Import Tips & Compliance
• Nuclear end-use requires NRC/DOE compliance letters beyond standard HTS docs
• Specify vacuum arc remelt compatibility in specs to justify low-hafnium classification

Low-Hafnium Zirconium Ingots
High-purity zirconium ingots with less than 1 part hafnium per 500 parts zirconium by weight, used in nuclear reactor components and chemical processing equipment. Classified under HTS 8109.21.00.00 as unwrought zirconium in ingot form, not yet processed into bars or rods. Meets the hafnium purity requirement for applications requiring minimal neutron absorption.
Zirconium Powder 99.5% Pure Low-Hafnium
Atomized zirconium powder containing less than 1:500 hafnium ratio, particle size -100 mesh, for powder metallurgy and additive manufacturing. HTS 8109.21.00.00 covers unwrought powders of this purity. Essential for aerospace components and medical implants due to corrosion resistance.
Reactor-Grade Zirconium Billets
Semi-finished zirconium billets, hafnium content 0.018% max (<1:500), diameter 8-12 inches for forging into tubesheets. HTS 8109.21.00.00 as unwrought since not hot/cold worked. Critical for pressurized water reactors (PWR).
High-Purity Zr Granules Low-Hafnium
Granular unwrought zirconium, <1:500 hafnium, 1-5mm size for vacuum arc melting stock. Used in sputtering targets and thin-film deposition. HTS 8109.21.00.00 covers granules as unwrought form before fabrication.
