Diethylamino-ethylidene phosphonamidic fluoride hydrochloride salt
A protonated salt form of N-(diethylamino)ethylidene phosphonamidic fluoride (both alkyl groups ≤C10), classified under HTS 2929.90.50.30 as it matches the exact description including corresponding alkylated or protonated salts. This compound serves as a reagent in organic synthesis, particularly for phosphoramidate derivatives used in pesticides or flame retardants. Chapter 29 notes confirm salts of nitrogen-function compounds stay with the parent organic structure.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the salt form exceeds specified alkylation or not protonated as described
Specific phosphonamidic fluorides and salts are distinctly listed; others default to the residual 'other' category in 2929.90.3000 per numerical order rule.
If for organo-inorganic salts with metal coordination
Chapter note (C)(3) classifies coordination compounds in the last applicable heading based on fragments, potentially shifting to 2931 if metal bonds present.
If containing both nitrogen and oxygen functions qualifying under heading 2942
Later headings like 2942 take precedence for specific other organic compounds with mixed functions per classification by numerical order.

Import Tips & Compliance
• Include protonation details in chemical documentation to validate salt classification; check for REACH/ TSCA pre-registration if destined for chemical synthesis; ensure packaging meets UN standards for corrosive fluorides
