2917.39Lower: 16.5% vs 41.5%

If contains other aromatic acid esters

Mixtures of different aromatic polycarboxylic esters fall under the general 'other' category rather than specific didecyl orthophthalates.

3812.20Lower: 15% vs 41.5%

If when supplied with compounded stabilizers

Compound plasticizers containing both DDOP and metal soap stabilizers classify as prepared rubber/plastic additives in 3812.

2909.49Lower: 15.5% vs 41.5%

If for lower molecular weight alcohol esters

Phthalate esters of C7-C9 alcohols fall under different ether/alcohol headings rather than C10 didecyl specification.

Import Tips & Compliance

Submit GC-MS analysis reports verifying decyl chain purity to distinguish from general phthalates under 2917.39

Include end-use declarations specifying industrial PVC applications to prevent scrutiny under consumer product regulations

Package in UN-approved chemical drums; improper labeling often leads to CBP holds for hazardous material verification
