Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing mainly petroleum oils and still usable
Petroleum-based hydraulic fluids fit for use fall under heading 2710 per chapter note exclusion, not wastes.
If for other hydraulic fluid wastes from non-specified sources
Non-note 6 wastes go to 3824.90, but hydraulic fluids explicitly listed in 3825 chapter note.
