Subheadings
Products classified under Tariff item 8105.30.00
Cobalt Alloy Turbine Blade Scrap
> Scrap from superalloy turbine blades containing cobalt, nickel, and chromium, sourced from aerospace engine overhauls. These blades are no longer usable as articles and are destined for metal recovery, thus qualifying as waste and scrap of cobalt under tariff item 8105.30.00.
Cobalt Brazing Alloy Scrap
> Scrap rods and wire from cobalt-based brazing alloys used in tool manufacturing. These are discarded as waste from production processes and are valued for their cobalt content, meeting the definition of waste and scrap under heading 81.05.
Cobalt Chemical Catalyst Scrap
> Spent cobalt-based catalysts from petrochemical processes, in pelleted or powdered form, containing cobalt oxide on supports. These are no longer effective as catalysts and are recovered for their cobalt content, classifying as waste and scrap of cobalt.
Cobalt Dental Alloy Scrap
> Scrap from cobalt-chrome dental prosthetics and crowns, collected from dental labs. These items are discarded after fabrication or use and are recovered for their cobalt content, fitting the definition of waste and scrap under tariff item 8105.30.00.
Cobalt Foam Filter Scrap
> Spent cobalt foam filters from molten metal casting, saturated with impurities. These filters have reached the end of their useful life and are recovered for cobalt recycling, making them waste and scrap under tariff item 8105.30.00.
Cobalt Magnet Scrap
> Scrap from Alnico permanent magnets containing cobalt, aluminum, and nickel, rejected from manufacturing or end-of-life electronics. These magnets are no longer usable and are processed for metal recovery, classifying as waste and scrap of cobalt.
Cobalt Pigment Manufacturing Scrap
> Waste from production of cobalt blue pigments (CoAl2O4), as filter cakes or off-spec powder. This material is discarded during pigment manufacturing and is recovered for its cobalt content, qualifying as waste and scrap under tariff item 8105.30.00.
Cobalt Salt Electroplating Scrap
> Anode scrap and sludges from cobalt electroplating baths for wear-resistant coatings. These residues are spent and recovered for cobalt recycling, fitting the definition of waste and scrap under tariff item 8105.30.00.
Cobalt Scrap from Battery Recycling
> Waste and scrap consisting of cobalt recovered from spent lithium-ion batteries, typically in the form of shredded battery cells or black mass containing cobalt oxide. This material is destined for metal recovery, classifying as waste and scrap of cobalt.
Cobalt Superalloy Jet Engine Scrap
> Dismantled scrap from cobalt-bearing superalloys in jet engine components like vanes. These parts are no longer airworthy and are recovered for their cobalt content, qualifying as waste and scrap under tariff item 8105.30.00.
Cobalt Tool Steel Scrap
> Scrap from high-speed tool steel containing 5-12% cobalt, generated from worn cutting tools and dies. This scrap is primarily valued for its cobalt content and is recovered for metallurgical use, classifying as waste and scrap under tariff item 8105.30.00.
Cobalt Wire Drawing Scrap
> Fine swarf and turnings from cobalt wire production for medical implants and springs. These by-products are generated during manufacturing and are recovered for cobalt recycling, fitting the definition of waste and scrap under tariff item 8105.30.00.
Spent Cobalt Desiccant Scrap
> Used silica gel desiccants impregnated with cobalt chloride indicator, spent from industrial drying. These are no longer effective and are recovered for their cobalt content, qualifying as waste and scrap under tariff item 8105.30.00.
