U.S. imports of compound plasticizers for rubber or plastics (HS 381220) totaled $6.8M in April 2026, traded with 19 countries.
Importers of Compound Plasticizers for Rubber or Plastics paid $645K in duties in April 2026 — an effective duty rate of 16% on $3.9M in dutiable value, based on actual customs collections rather than the published tariff schedule. Compound Plasticizers for Rubber or Plastics imports of $6.8M in April 2026 ran 17% above the year-to-date monthly average of $5.9M.
Last updated: April 2026 dataCompound plasticizers — multi-component blends of phthalates, adipates, trimellitates, or polymeric plasticizers formulated to impart flexibility and processability to rubber and plastic compounds — are classified under this heading, with the US schedule separating aromatic-containing formulations (3812201000) from other types (3812205000). Canada leads US import supply, followed by Germany and Thailand, reflecting both USMCA-integrated North American compounding operations and European specialty chemical expertise. Importers of phthalate-based plasticizers should be aware of CPSC restrictions on certain phthalates in children's articles, which can affect admissibility of finished goods but generally do not restrict the import of the plasticizer chemical itself.

Yes, 3812201000 and 3812205000 may carry different normal trade relations (NTR) duty rates, and Section 301 exposure for Chinese-origin goods can also differ by line. Importers should confirm the correct subheading based on the plasticizer's chemical composition — specifically whether the formulation contains aromatic or modified aromatic structures — and verify current duty treatment with a licensed customs broker.
A detailed technical data sheet or certificate of composition from the manufacturer identifying each component and its weight percentage is the foundation for classification. For blends where the aromatic content is near a threshold, a laboratory analysis confirming the presence or absence of aromatic ring structures may be necessary to defend the chosen subheading in a CBP audit.
