Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If terephthalate isomer (linear 1,4-benzenedicarboxylic acid)
Dioctyl terephthalates classify separately under 2917.36 as aromatic polycarboxylic acid positional isomers have distinct headings.
If when imported as reaction intermediate before full esterification
Partially esterified phthalic acid derivatives may classify under monocarboxylic acid esters in 2909 per Chapter 29 ester rules.
If formulated as goods specified in Note 1 pesticide preparations
Phthalates used as pesticide carriers/formulations exclude from Chapter 29 per chapter exclusions.

Import Tips & Compliance
• Provide REACH registration and SVHC declarations due to phthalate restrictions in EU and emerging US regulations
• Label containers with CAS 117-81-7 and flash point data (196°C); improper documentation triggers DOT hazardous material violations
• Confirm >99% purity via GC-MS analysis; impurities >1% risk reclassification as 2917.39 other phthalate esters

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.
Dioctyl Orthophthalate Stabilized Grade
Industrial-grade dioctyl orthophthalate with added epoxidized soybean oil stabilizer for enhanced PVC processing stability. Qualifies under HTS 2917.32.00.00 per Chapter 29 note (f) allowing stabilizers necessary for preservation/transport. The primary dioctyl orthophthalate structure determines classification.
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.
