Bis(2-ethylhexyl) Adipate (DEHA)
DEHA is a widely used adipic acid diester serving as a primary plasticizer for PVC in applications requiring low-temperature flexibility. Falls under HTS 2917.12.5000 as 'other' adipic acid esters, being a chemically defined acyclic polycarboxylic acid derivative. Excluded from other chapters per note (A) ester classification rule.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported with antioxidant stabilizers exceeding Chapter 29 note (f) limits
Stabilizer additions beyond preservation levels shift to chemical mixtures classification
If analyzed as aromatic polycarboxylic acid derivative
Aromatic vs acyclic structure determines subheading within 2917
If polymerized or reacted into unsaturated polyester resins

Import Tips & Compliance
• Submit TSCA certification for US imports; phthalate-free declaration increasingly required
• For >1000kg shipments, pre-register with EPA; verify DOT classification as combustible liquid
