Alternative Classifications

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

2917.39.20.00Same rate: 41.5%

If dioctyl rather than diisodecyl orthophthalate chains

Different alkyl chain lengths (C8 vs C10-C11 branched) determine specific subheading within 2917.33 vs other phthalates.

3812.31.00.00Same rate: 41.5%

If contains >10% effective accelerators or vulcanizing agents

Additives rendering it suitable for rubber compounding exclude pure plasticizers from Chapter 29.

3208.90.00.00Lower: 38.2% vs 41.5%

If used primarily as paint additive rather than general plasticizer

Specialty applications may shift classification to Chapter 32 synthetic organic products for specific uses.

Import Tips & Compliance

Ship in ISO tanks or drums with nitrogen blanketing to prevent oxidation, maintaining purity for Chapter 29 classification

Declare exact CAS number 26761-40-0 on commercial invoice; deviations trigger re-examination for alternative classifications
