Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when pre-mixed into racing or specialty gasoline
Blended into finished fuel products, it becomes classified as gasoline under heading 2710 rather than a separate additive.
If reformulated with oxidation inhibitors for storage
Prepared additives combining antiknock with gum/oxidation inhibitors shift to the multi-function subheadings.
If for industrial solvent blends containing TEL
Non-fuel applications as prepared binders or solvents fall outside 3811 into other chemical mixtures.
