N,N-Diethylphosphoramidic dichloride
A dialkyl phosphoramidic dihalide with ethyl groups on nitrogen and two chlorine atoms, fitting HTS 2929.90.50.18 as 'other' N,N-dialkyl (methyl, ethyl, n-propyl or isopropyl) phosphoramidic dihalides. Used primarily in synthesis of flame retardants and insecticides. Its precise chemical definition aligns with Chapter 29 heading for compounds with other nitrogen functions.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for other nitrogen function compounds excluding dihalides
Non-dihalide phosphoramidates would classify earlier in 2929.90 per numerical order rule in Chapter notes.
If treated as inorganic halides
Inorganic phosphorus halides fall in Chapter 28, but organic nitrogen function takes precedence in Chapter 29.
If for heterocyclic compounds with nitrogen
If the molecule forms a heterocyclic ring, it shifts to 2933; this acyclic dihalide stays in 2929.

Import Tips & Compliance
• Submit NMR or GC-MS spectra to confirm structure matching the subheading; impurities must not exceed Chapter 29 note (a) thresholds
• Declare as hazardous material under DOT 49 CFR; use UN-approved packaging for corrosive liquids
• Watch for reclassification if dissolved in solvents beyond transport needs—per note (e), solutions must be solely for safety
