Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when stabilizer content renders suitable for specific PVC processing
Exceeds Chapter 29 note (f) limits; becomes prepared mixture of Chapter 38 rather than pure compound with incidental stabilizer.
If contains other orthophthalate esters as impurities
Mixtures of orthophthalic acid isomers classify in residual 2917.39 rather than pure dioctyl orthophthalates.

Import Tips & Compliance
• Document stabilizer as <1% by weight and solely for transport stability to maintain Chapter 29 classification
• Include heat stability test data showing performance equivalent to pure DOP; excessive additives trigger 3824 mixture classification
• Ensure bulk containers have nitrogen blanketing certification to prevent oxidation during ocean transit

Dioctyl Phthalate (DOP)
Dioctyl phthalate (DOP), chemically bis(2-ethylhexyl) phthalate, is the most common dioctyl orthophthalate used as a plasticizer for PVC. It falls under HTS 2917.32.00.00 as it is a derivative of orthophthalic acid (1,2-benzenedicarboxylic acid) esterified with two octyl alcohol molecules. This aromatic polycarboxylic acid ester is supplied as a clear, oily liquid for industrial plasticizing applications.
Bis(2-Ethylhexyl) Phthalate (DEHP)
Bis(2-ethylhexyl) phthalate (DEHP), synonymous with DOP, is a branched-chain dioctyl orthophthalate plasticizer for flexible PVC products. Classified under HTS 2917.32.00.00 as the principal commercial form of dioctyl orthophthalates derived from phthalic anhydride and 2-ethylhexanol. Used extensively in wire insulation, flooring, and medical tubing.
High-Purity Dioctyl Phthalate 99.5%
Ultra-high purity dioctyl orthophthalate (99.5% min) for medical-grade PVC and sensitive electronics applications. Falls squarely under HTS 2917.32.00.00 as chemically defined dioctyl orthophthalate per Chapter 29 note (a). Supplied in nitrogen-purged drums to maintain specification.
DOP Plasticizer Technical Grade
Technical grade dioctyl orthophthalate meeting ASTM D1045 standards for general PVC plasticizing. Classified HTS 2917.32.00.00 as the dioctyl orthophthalate molecule dominates per Chapter 29 classification rules. Widely used in flooring, wallcoverings, and coated fabrics.
