Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If total dinonyl/didecyl content <85%
Insufficient concentration of specified phthalates results in classification as general aromatic carboxylic acid derivatives.
If imported as ready-to-use plasticizer formulation
Commercial preparations diluted with processing oils classify as chemical mixtures rather than pure compounds.
If surface-active formulations
When combined with surfactants for specific processing aids, falls under organic surface-active preparations.

Import Tips & Compliance
• Provide chromatogram data showing combined dinonyl/didecyl content ≥90% to qualify for specific 2917.33.0050 classification
• Declare exact isomer ratios on commercial invoice; variations may trigger 2917.39 reclassification by customs chemists
• Ensure DOT/UN proper shipping names match 'aromatic ester plasticizer' to avoid hazmat surcharges
