Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified solely as phosphorus trichloride without oxide component
Pure chlorides of phosphorus fall under 2812.10, but oxychloride includes oxygen, shifting to 2812.12
If imported as a formulated mixture or solution for retail/industrial use
Chemical preparations or mixtures not chemically defined are excluded from Chapter 28 per notes and go to 3824
