O-(3-Chloropropyl) O-[4-Nitro-3-(Trifluoromethyl)phenyl] Methylphosphonothionate
This is a specific halogenated organo-phosphorus compound featuring both chlorine and fluorine atoms directly linked to carbon in its structure, along with a phosphorus atom bonded to oxygen and carbon chains. It falls under HTS 2931.53.00.00 as a named halogenated organo-phosphorous derivative within Chapter 29's scope for separate chemically defined organic compounds containing nonmetal atoms like phosphorus linked to carbon. Primarily used as a chemical intermediate in agrochemical or pharmaceutical synthesis.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as a salt of this phosphonothionate rather than free base
Inorganic salts of organic phosphorus compounds may classify with parent under 2904 per Chapter notes, but only if not fitting 2931 hierarchy.
If the compound is reclassified as primarily organo-sulfur due to thionate dominance
Organo-sulfur compounds in heading 2930 take precedence if sulfur-carbon linkage defines its chemical character over phosphorus, per Chapter 29 notes.
If when imported as a formulated mixture or technical grade with impurities >5%
Mixtures of organic compounds not chemically defined fall under Chapter 38; pure compounds stay in Chapter 29.

Import Tips & Compliance
• Provide detailed chemical analysis (NMR, MS, purity certificate) to verify identity and confirm classification under 2931.53 as this exact compound
• Include Safety Data Sheet (SDS) and end-use statement; phosphonothionates may trigger TSCA notification or pesticide registration if for agrochemical use
• Avoid misclassification by ensuring shipment is pure compound, not diluted beyond Chapter 29 note (e) limits for solvents
