U.S. imports of triethyl phosphite (HS 292024) totaled $91K in June 2026, traded with 1 country.
Importers of Triethyl Phosphite paid $12K in duties in June 2026 — an effective duty rate of 14% on $91K in dutiable value, based on actual customs collections rather than the published tariff schedule. Triethyl Phosphite imports of $91K in June 2026 ran 14% below the year-to-date monthly average of $106K.
Triethyl phosphite is a trialkyl phosphite ester used as a ligand in catalysis, a flame-retardant intermediate, and a building block in organophosphorus chemistry, classified under tariff line 2920240000. India and China are the dominant US suppliers. Section 301 tariffs may apply to Chinese-origin shipments, and TSCA import certification is a standard compliance step for this industrial chemical.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
While both are trialkyl phosphites, triethyl phosphite's larger ethyl groups give it different reactivity and solubility characteristics. It is more commonly used as a ligand in transition-metal catalysis and in Michaelis-Arbuzov reactions for pharmaceutical intermediates, whereas trimethyl phosphite is more prevalent in flame-retardant synthesis. This distinction can affect which supplier specifications are acceptable for a given manufacturing process.
With India and China as the two dominant suppliers, US importers face meaningful geographic concentration risk. Any disruption — whether from export controls, logistics bottlenecks, or Section 301 tariff changes affecting Chinese-origin goods — can tighten availability. Maintaining dual-source qualification with both Indian and Chinese producers is a common risk-mitigation strategy.
