Diisodecyl Orthophthalate (DIDP) Plasticizer from Germany

Diisodecyl orthophthalate (DIDP) is a branched-chain phthalate ester used primarily as a high-performance plasticizer for polyvinyl chloride (PVC) resins. It falls under HTS 2917.33.0010 as a specific didecyl orthophthalate derivative within aromatic polycarboxylic acid esters. This chemical compound enhances flexibility and durability in plastics without impurities that would alter its classification.

Import Tips

Verify chemical purity via Certificate of Analysis (CoA) to confirm it meets Chapter 29 definition as a separate chemically defined compound without disqualifying impurities

Include Safety Data Sheet (SDS) and TSCA certification for EPA compliance, as phthalates face regulatory scrutiny under chemical import rules

Avoid misclassification as a mixture; ensure packaging labels it solely as DIDP to prevent reclassification under heading 3824 for chemical preparations
