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.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If hafnium content exceeds 1 part per 500 parts zirconium
Higher hafnium variants fall under the residual 'other' subheading 8109.90.00, often nuclear-grade.
If alloyed as zirconium-clad steel strip
Clad products with steel base primarily steel under Chapter 72, not pure zirconium articles.
If machined into finished semiconductor parts
Fully fabricated semiconductor manufacturing equipment parts shift to Chapter 84/85 machinery headings.

Import Tips & Compliance
• Provide spectrographic analysis confirming hafnium levels to prevent misclassification as higher-hafnium nuclear material
• Label shipments clearly as 'commercial grade zirconium' with ASTM B551 specs to aid CBP review
