Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used exclusively as metal-working coolant
Certain metal-working fluids have dedicated provisions outside quenching/cutting.
If for automotive engine oils
Motor oils classified separately even if similar base composition.
If prepared with significant synthetic non-petroleum additives
Chemical preparations not primarily petroleum-based shift to Chapter 38.
