Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If high purity without unsaturated impurities
Pure saturated trichloroethylene classified under 2903.21 vinyl chloride derivatives.
If formulated organic solvent composition
Retail or formulated solvents excluded to chapter 38 per note 2(k).
If aqueous cleaning solution
Water-dissolved preparations beyond note 2(d) standard go to mixtures.
