Diisodecyl Orthophthalate (DIDP) Plasticizer
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended with other plasticizers or additives exceeding 1% impurities
Blends or mixtures of organic compounds fall under Chapter 38 as chemical preparations rather than pure compounds of Chapter 29.
If dissolved in mineral oil for transport exceeding safety-only solvent limits
Solutions in solvents that render them suitable for specific use (not just safety/transport) are excluded from Chapter 29 per chapter note 2(e).
If chemically identical but imported under general aromatic phthalate esters
Other named phthalate esters not specifically listed as dinonyl/didecyl orthophthalates fall into the residual provision within the same heading group.

Import Tips & Compliance
• 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
