Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If ester of other aromatic polycarboxylic acid (e.g., terephthalic)
Isomer-specific classification; orthophthalic (1,2-) vs terephthalic (1,4-) changes subheading within same heading.
If for formulated plasticizer mixtures with stabilizers
Commercial preparations with multiple active ingredients classified as mixtures in Chapter 38, not pure compounds.
If containing >20% ether oxygen content
Ether-function compounds take precedence per Chapter 29 classification note prioritizing later numerical headings.
