U.S. imports of compound plasticizers, antioxidizers & stabilizers for rubber or plastics (SITC 59893) totaled $42.5M in April 2026, traded with 31 countries.
Importers of Compound Plasticizers, Antioxidizers & Stabilizers for Rubber or Plastics paid $5.0M in duties in April 2026 — an effective duty rate of 16% on $30.6M in dutiable value, based on actual customs collections rather than the published tariff schedule. Compound Plasticizers, Antioxidizers & Stabilizers for Rubber or Plastics imports of $42.5M in April 2026 ran 32% above the year-to-date monthly average of $32.2M.
Last updated: April 2026 dataCompound plasticizers, antioxidants, and stabilizer packages for rubber and plastics are performance-critical additives that control flexibility, thermal stability, UV resistance, and processing behavior in polymer manufacturing. Phthalate-based plasticizers have faced significant regulatory pressure — including CPSC restrictions on certain phthalates in children's articles — driving demand toward non-phthalate alternatives such as DINCH and DOTP. Antioxidant and stabilizer systems, including hindered phenols and phosphite blends, are often proprietary formulations where supplier qualification and consistency of the additive package directly affect end-product compliance with food-contact or medical-device regulations.

CPSC regulations under the Consumer Product Safety Improvement Act (CPSIA) permanently restrict DEHP, DBP, and BBP in children's toys and child-care articles, with additional restrictions on DINP, DPENP, DHEXP, and DCHP. Importers of plasticized articles — not just the plasticizer itself — must ensure compliance; however, the raw plasticizer compound imported for industrial use is classified and traded separately from the finished article restrictions.
Yes. Stabilizers and antioxidants intended for use in food-contact plastics must comply with FDA regulations governing indirect food additives, which specify permitted substances and migration limits. For medical-device applications, the polymer additive system must be documented as part of the device's biocompatibility testing under ISO 10993 standards. Importers supplying these sectors should obtain supplier declarations confirming compliance with the applicable FDA or ISO framework.
