Impure Tin Pigs
Tin pigs containing iron and arsenic impurities from scrap melting without electrolytic refining. Exceeds commercial purity limits requiring remelt and refining, qualifying under HTS 9817.00.90.40 provisions.
Defective Aluminum Billets
Aluminum billets produced from melted down scrap metal without sweetening, alloying, or purifying, exhibiting surface defects and cracks that render them unsuitable for direct extrusion or forging. These defective billets require complete remelting and reprocessing before commercial use, qualifying under HTS 9817.00.90.40 as unwrought aluminum in billet form unfit for use without remanufacture.
Cracked Titanium Billets
Titanium billets with internal cracks and surface delamination from scrap consolidation without alloying or vacuum arc remelting. Unfit for aerospace forging without complete remelt, covered by HTS 9817.00.90.40 provisions.
Porous Cobalt Ingots
Cobalt ingots exhibiting porosity and shrinkage cavities from scrap melting without degassing or refining. Cannot be used for superalloy production without remelting, specifically provided for under HTS 9817.00.90.40.
Surface-Defective Molybdenum Billets
Molybdenum billets with heavy surface oxidation and laps from scrap pressing without chemical cleaning or electron beam remelting. Requires complete remelt for commercial wire production under HTS 9817.00.90.40.
Delaminated Zirconium Ingots
Zirconium ingots with delamination and piping defects from scrap arc melting without consumable electrode remelting. Nuclear-grade material requires complete remelt per HTS 9817.00.90.40 standards.
