Zirconium Borings
Zirconium borings are fine drill chips and residues generated during the machining of zirconium components, particularly in nuclear reactor fabrication. These materials are classified as waste and scrap under tariff item 8109.39.00 because they are not usable as finished articles and do not meet the definitions of unwrought zirconium or other specific forms.
Zirconium Clipping Waste
Zirconium clipping waste consists of sheared offcuts from zirconium sheet stock used in heat exchanger production. These clippings are not usable as sheets and are classified as other waste and scrap under tariff item 8109.39.00, distinct from unwrought zirconium or finished articles.
Zirconium EDM Wire Scrap
Zirconium EDM wire scrap is spent wire remnants from electrical discharge machining of zirconium molds. This fine wire waste is classified as other waste and scrap under tariff item 8109.39.00, supporting recycling in tool-and-die operations due to its precision-grade zirconium content.
Zirconium Fabrication Dust
Zirconium fabrication dust is fine particulate collected from sanding and polishing zirconium anodes in electroplating lines. This dust is classified as other waste and scrap under tariff item 8109.39.00 and requires explosion-proof handling due to its fine particle size and reactive nature.
Zirconium Filing Scrap
Zirconium filing scrap consists of fine filings from hand-finishing zirconium tubes for medical implants. These small-particle residues are classified as other waste and scrap under tariff item 8109.39.00, and their high purity makes them suitable for biomedical recycling.
Zirconium Grinding Swarf
Zirconium grinding swarf is abrasive-laden waste from surface grinding zirconium billets for turbine blades. This contaminated waste and scrap is classified under tariff item 8109.39.00 and requires cleaning before remelting to recover the zirconium.
