Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended with other plasticizers or additives for specific formulations
Mixtures of chemical compounds not chemically defined fall under Chapter 38 prepared binders, rather than pure Chapter 29 compounds.
If dissolved in hydrocarbon solvents exceeding transport safety thresholds
Solutions in solvents that render them suitable for specific uses move to Chapter 27 petroleum oils per Chapter 29 note 2(e).
If chemically incorporated into finished polyester resins or polymers
Polymerized forms become artificial resins classifiable in Chapter 39, not individual esters of Chapter 29.

Import Tips & Compliance
• Provide chemical purity certificates and CAS number (84-74-2) documentation to verify classification under Chapter 29 organic compounds
• Ensure proper labeling as a REACH/SVHC restricted substance due to reproductive toxicity concerns in many markets
• Avoid misclassification as a finished plastic product; classify based on chemical identity, not end-use application
