Import Tips & Compliance
• Provide HPLC/GC certificate showing <0.5% monoester or other impurities to prevent 2917.39 reclassification
• FDA Drug Master File reference required for medical PVC applications; include biocompatibility test summaries
• TSCA certification mandatory; failure to declare new chemical status incurs EPA penalties

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.
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.
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.
