Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If API gravity between 22-25 degrees
Narrower API ranges have specific subheadings like 2710.19.03 for medium-heavy residuals.
If bitumen-emulsion stabilized
Petroleum bitumen preparations exceeding 70% oil content are under heading 2713.
