Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If higher sulfur content specifications
Heavy fuels with distinct sulfur profiles may use different 'other' subheadings.
If bitumen-emulsion stabilized
Petroleum bitumen preparations shift to Chapter 27 bituminous mixtures.
If <70% petroleum oils or added lubricants
Preparations falling below 70% oil threshold become lubricating oil compositions.
