Last updated: September 2026 dataGrouped under tariff line 3825500000, this heading captures four distinct industrial fluid waste streams: spent metal-pickling liquors (typically strong acid solutions from steel processing), used hydraulic fluids, spent brake fluids, and waste anti-freeze (primarily ethylene or propylene glycol-based coolants). Each stream has a different chemical profile and end-of-life management pathway — spent pickling liquors are often acid-rich and corrosive, while waste anti-freeze is widely reclaimed for re-refining. Importers should verify RCRA hazardous-waste status for each specific fluid type, as corrosivity or toxicity characteristics can trigger listed or characteristic waste designations regardless of the fluid's origin.

The HS nomenclature consolidates these streams because they share a common commercial context — all are spent functional fluids from industrial or automotive operations — rather than a common chemistry. For regulatory purposes, each fluid type must still be assessed individually under RCRA to determine its hazardous-waste status and the applicable management standards.
Waste ethylene glycol anti-freeze is widely reclaimed through distillation or reverse osmosis for reuse as coolant. As long as the material enters the US as a waste stream destined for reclamation, it remains classifiable here. Once reclaimed to commercial-grade specification, the recovered product would be classified under the appropriate heading for glycols rather than as a waste.
