Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If formulated as herbicide, insecticide, or fungicide containing fonofos as active ingredient
Pesticide preparations with active ingredients like fonofos are classified under Chapter 38 heading 3808, not as pure compounds in Chapter 29.
If containing organo-phosphorus compounds without qualifying sulfur linkage
Organo-inorganic compounds with phosphorus but not meeting organo-sulfur criteria shift to heading 2931 per chapter notes excluding sulfonated derivatives.
If classified primarily as halogenated or sulfur-containing hydrocarbon derivative
If the compound's structure emphasizes hydrocarbon base with sulfur over organo-sulfur function, it may fall under earlier acyclic hydrocarbon derivatives in 2903.

Import Tips & Compliance
• Obtain EPA registration and import approval prior to shipment as fonofos is a restricted pesticide; provide detailed chemical purity certificates and SDS sheets
• Verify compliance with TSCA and FIFRA; common pitfall is inadequate residue testing documentation
