Dioctyl Terephthalate (DOTP)
Dioctyl terephthalate (DOTP) is an aromatic polycarboxylic acid ester derived from terephthalic acid, used primarily as a non-phthalate plasticizer for PVC applications. It falls under HTS 2917.39.20.00 as a plasticizer within aromatic polycarboxylic acid derivatives. This clear, odorless liquid enhances flexibility in flooring, cables, and medical devices.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as phthalate ester
Phthalic anhydride esters like DOP fall under specific phthalate subheading 2917.37, but DOTP as terephthalate goes to 'other' aromatic plasticizers.
If imported as formulated PVC additive mixture
Mixtures containing plasticizers with other additives exceed 70% purity threshold for Chapter 29, moving to Chapter 38 chemical preparations.
If ester purity <70% with mineral oil diluent
Plasticizer esters diluted with petroleum oils for viscosity fall under Chapter 27 hydrocarbon mixtures rather than pure Chapter 29 compounds.

Import Tips & Compliance
• Verify chemical purity and provide Certificate of Analysis (CoA) to confirm classification as plasticizer, not general ester
• Ensure proper labeling with CAS number (6422-86-2) and safety data sheets for hazardous material handling
• Avoid misclassification as phthalates under 2917.37 by documenting terephthalate structure
