U.S. imports of aromatic phosphoric esters and their salts (HS 291990) totaled $9.9M in July 2026, traded with 22 countries.
Importers of Aromatic Phosphoric Esters and Their Salts paid $713K in duties in July 2026 — an effective duty rate of 7.4% on $9.7M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Triphenyl phosphate and related aromatic phosphoric esters serve primarily as flame retardants and plasticizers in polymers, coatings, and hydraulic fluids, with the US schedule distinguishing triphenyl phosphate (2919901500), aromatic plasticizers (2919902500), and non-aromatic phosphoric ester plasticizers (2919905010 and 2919905050). Germany leads US import supply, with China and India also significant sources. Several aromatic phosphate esters have attracted regulatory scrutiny as potential endocrine disruptors, and importers supplying the consumer-goods or food-contact sectors should monitor evolving EPA and FDA guidance.

The aromatic designation applies when the ester group is directly attached to an aromatic ring (e.g., phenyl groups in triphenyl phosphate). Non-aromatic phosphoric esters — where the ester groups are aliphatic — fall under lines 2919905010 and 2919905050. When a compound contains both aromatic and aliphatic ester groups, the predominant structural character and GRI rules govern classification; a binding ruling from CBP is advisable for mixed-structure compounds.
Many phosphoric ester plasticizers classified in Chapter 29 have been included in Section 301 tariff actions on Chinese-origin goods. The specific lines affected and any product exclusions can change, so importers should verify current Section 301 applicability and check for any active exclusion requests or renewals with a licensed customs broker before sourcing decisions are finalized.
