How to choose the right subheading

Determine whether the product is a thiophosphoric ester (phosphorodithioate) or a phosphite ester.
For thiophosphoric esters, choose 2920.11.00.00 for parathion or parathion-methyl; for other products, use 2920.19 and decide aromatic vs other.
Match named phosphite esters to 2920.21.00.00 through 2920.24.00.00, and use 2920.29.00.00 for other phosphite esters.
For other products, decide aromatic vs other and whether the product is a pesticide or ethylene carbonate.
Check whether the goods are a salt or a halogenated, sulfonated, nitrated or nitrosated derivative of the base ester.
