Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing arsenic or similar organo-inorganic metals
Organo-inorganic compounds with nonmetals like arsenic fall under 2931.00, preceding phosphorus derivatives in chapter order
If classified primarily as organo-sulfur compound
Chapter notes direct organo-sulfur compounds to heading 2930 regardless of phosphorus content
If imported as mixture with solvents exceeding transport allowances
Solutions beyond safety/transport exceptions fall under mixtures of Chapter 38
