Chromium Evaporation Boat Scrap
Discarded chromium evaporation boats used in vacuum deposition processes for thin-film coating in optics and electronics manufacturing. These boats are considered waste and scrap of chromium, as they are no longer usable for their original purpose after single-use deposition cycles.
8112.22.00Chromium Metal Scrap from Electroplating Operations
Waste chromium metal generated from electroplating baths and rinsing processes in manufacturing facilities. This material is classified as scrap of chromium, a base metal under Chapter 81, and is not usable as-is for further electroplating operations.
8112.22.00Chromium Powder Recovery Scrap
Atomized chromium powder rejects and sieve oversize from thermal spray feedstock production. These materials are considered chromium waste and scrap, as they do not meet particle size specifications for use in plasma spray coatings.
8112.22.00Chromium Sputtering Target Scrap
Spent chromium sputtering targets from physical vapor deposition systems in semiconductor and hard disk manufacturing. These targets are considered chromium waste and scrap after erosion during thin-film deposition, as they can no longer be used effectively.
8112.22.00Chromium Vacuum Arc Remelt Scrap
Skull and button scrap from vacuum arc remelting furnaces purifying aerospace-grade chromium. These residues and electrode stubs are considered high-purity chromium waste from ingot production, not usable as-is for further refining.
8112.22.00Chromium Wire Drawing Waste
Scrap from drawing high-purity chromium wire for thermocouples and heating elements, including breakages and trim ends. This material is classified as chromium waste and scrap, as it is not usable for wire production due to work-hardening.
8112.22.00Defective Chromium Anodes
Rejected solid chromium anodes from hard chrome plating tank production due to casting defects. These anodes are considered chromium waste and scrap, as they are unfit for electroplating service and returned directly from quality control.
8112.22.00High-Purity Chromium Foil Scrap
Trimmings and rejects from ultra-thin chromium foil rolls used in architectural glass coatings and flex circuits. This material is considered chromium waste and scrap, valued for its 99.99% purity in sputtering targets, but not usable as foil.
8112.22.00Industrial Chromium Turning Scrap
Machining turnings and chips from high-purity chromium rods used in aerospace and electronics. These are classified as chromium scrap, distinct from common steel turnings due to their base metal purity, and are not usable as rods.
8112.22.00Spent Chromium Cathodes from Electrolytic Refining
Exhausted cathode sheets from electrolytic chromium recovery cells in metal finishing plants. This pure chromium scrap is dissolved during purification cycles and is no longer usable as cathodes, but offers high recovery yield after re-dissolution.
