Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If >90% single unsaturated alcohol like oleyl
High-purity unsaturated alcohols classified individually under 2905.22 rather than as mixed preparations.
If when combined with siloxanes or mineral oils
Defoamer formulations with silicones or oils move to surface-active preparations in Chapter 34.
If mixtures with nicotine or other pesticide precursors
Specific pesticide-related chemical mixtures have separate subheadings based on listed active substances.
