Last updated: July 2026 dataDioctyl orthophthalates (DOP/DEHP) are high-volume PVC plasticizers that have faced increasing regulatory scrutiny in consumer and medical applications due to endocrine-disruption concerns, shifting demand toward non-phthalate alternatives even as industrial use continues. South Korea is the leading US supplier under this heading, followed by Mexico, whose proximity and manufacturing base support cost-competitive supply. All imports enter under a single 10-digit line (2917320000). Importers should be aware that DEHP is subject to restrictions under various state and federal regulations for certain end-use applications, and product from some origins may carry Section 301 exposure.

DEHP (a specific dioctyl orthophthalate) is permanently banned in concentrations above 0.1% in children's toys and child care articles under the Consumer Product Safety Improvement Act (CPSIA). Additional state-level restrictions may apply. Importers should confirm the intended end-use and consult legal counsel on applicable product safety requirements before distribution.
South Korea's dominance reflects large-scale petrochemical integration among Korean producers. While this provides reliable volume, it also means buyers are exposed to concentration risk — any disruption to Korean production or shipping can tighten the US market quickly. Mexico's position as the second-ranked supplier offers a nearshore alternative that can reduce lead times and logistics costs.
