Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If purity below technical thresholds or with added stabilizers
Impurity levels or additives may shift to other organo-inorganic compounds if not meeting 'separate compound' criteria.
If misidentified without phosphorus characterization
Halogenated hydrocarbons lacking P-C bond would fall under saturated halogenated derivatives in heading 2903.
If pre-formulated into pesticide intermediates
Goods of heading 3808 for pesticide intermediates exclude pure Chapter 29 compounds.
