Pure Diisodecyl Orthophthalate DINCH Alternative

High-purity diisodecyl orthophthalate serves as a non-phthalate alternative plasticizer in sensitive applications like medical PVC tubing. Classified under HTS 2917.33.0010 due to its specific chemical structure as a didecyl orthophthalate ester of 1,2-benzenedicarboxylic acid. It meets Chapter 29 requirements for separate chemically defined aromatic polycarboxylic acid derivatives.

Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

2917.33.00Same rate: 41.5%

If linear chain isomer rather than branched isodecyl groups

Heading distinguishes diisodecyl (branched) from other didecyl orthophthalates, with separate 10-digit statistical suffixes.

3824.99Lower: 15% vs 41.5%

If stabilized with >0.5% antioxidants for long-term storage

Additions beyond necessary stabilizers for preservation/transport exclude from Chapter 29 per note 2(f), moving to preparations.

2909.60.20.00Lower: 40.5% vs 41.5%

If imported as alcohol component rather than ester

Isodecanol (the alcohol precursor) classifies under monohydric alcohols, not phthalate esters.

Import Tips & Compliance

Provide GC-MS analysis confirming >99% purity to distinguish from mixtures and maintain Chapter 29 classification

For medical-grade imports, include FDA Drug Master File references alongside standard chemical documentation

Label drums clearly as 'Diisodecyl Orthophthalate CAS 26761-40-0' to facilitate CBP verification against HTS specificity
