O-Ethyl N,N-Dimethyl Phosphoramidocyanidate
This is a specific non-halogenated organo-phosphorus compound featuring an O-ethyl group (C2 alkyl) and N,N-dimethyl phosphoramidocyanidate structure, classified under HTS 2931.49.00.05 as it matches the exact chemical definition of O-alkyl (≤C10) N,N-dialkyl phosphoramidocyanidates. It falls within Chapter 29 for separate chemically defined organic compounds with phosphorus directly linked to carbon.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing arsenic or other nonmetal/metal directly linked to carbon
Compounds with additional heteroatoms beyond P-N-C structure fall under other organo-inorganic compounds in 2931.90.
If classified primarily as phosphine, phosphite or phosphate rather than phosphoramidocyanidate
Other phosphorous inorganic or organic compounds not specifically matching the phosphoramidocyanidate definition go to Chapter 28 heading 2853.
If imported as pesticide active ingredient rather than pure chemical
Herbicides or goods specified in Note 1 to Chapter 38 may take precedence over Chapter 29 classification.

Import Tips & Compliance
• Provide detailed chemical analysis certificates confirming the O-alkyl chain length ≤C10 and specific N,N-dialkyl groups to verify HTS 2931.49.00.05 classification
• Comply with Chemical Weapons Convention (CWC) Schedule 2 requirements; obtain End-Use Certificates for import authorization
• Avoid misclassification as halogenated derivatives (2931.31) by ensuring no halogen atoms are present in the molecular structure
