Zinc Galvanizing Kettle Dross
Zinc galvanizing kettle dross is the residue collected from molten zinc baths used in hot-dip galvanizing of steel. It consists of zinc oxides, intermetallic compounds, and metallic zinc, and it is removed from the kettle as waste. This material qualifies under tariff item 7902.00.00 as zinc waste and scrap because it is a by-product of the galvanizing process.

Recycled Zinc Lithography Plate Scrap
Recycled zinc lithography plates are used printing plates from offset printing presses, typically made of rolled zinc that has been stripped of its image coating. Once spent, these plates are collected and sold as scrap for remelting, and they qualify as zinc waste and scrap under tariff item 7902.00.00 because they are metal goods definitely not usable as printing plates in their current state.
Used Zinc Roof Flashing Scrap
Used zinc roof flashing scrap consists of rolled zinc sheets and flashing removed from buildings during demolition or renovation. The material is collected for recycling and is considered zinc waste and scrap under tariff item 7902.00.00 because it is no longer usable as roofing material due to wear, cutting, or removal.
Zinc Alloy Machining Turnings
Zinc alloy machining turnings are fine shavings and borings produced during CNC machining of zinc alloy parts, such as locks, gears, and fittings. These turnings are collected for remelting in die-casting foundries and qualify as zinc waste and scrap under tariff item 7902.00.00 because they are metal goods not usable as finished parts.
Zinc Anode Scrap from Cathodic Protection
Zinc anode scrap comes from spent sacrificial anodes used in cathodic protection systems on ship hulls, pipelines, and offshore platforms. These anodes are consumed over time and are replaced, with the remnants collected as scrap for recycling into new anodes or other zinc products, qualifying under tariff item 7902.00.00 as zinc waste and scrap.
Zinc Battery End-of-Life Scrap
Zinc battery end-of-life scrap consists of zinc casings and anodes recovered from recycled alkaline or zinc-carbon batteries. After processing to separate metallic zinc from other battery components, the zinc fraction is sold as scrap for remelting, qualifying under tariff item 7902.00.00 as zinc waste and scrap.
Zinc Die Casting Gate and Riser Scrap
Zinc die casting gate and riser scrap is excess metal removed from gates, risers, and overflows during high-pressure die casting of Zamak alloy components. This clean revert scrap is typically remelted in-house or sold to foundries, and it qualifies under tariff item 7902.00.00 as zinc waste and scrap because it is not usable as finished parts.
