Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If incorporated into finished fragrance mixtures for retail
Mixtures prepared as consumer fragrance products fall under Chapter 33, not bulk chemicals.
If specifically dioctyl esters like DOP/DINP
Subheading 2917.34.10 covers named dioctyl phthalates; other alkyl esters are 'other'.
If for plasticizer preparations containing multiple phthalates
Prepared additives/blends shift from pure compounds to Chapter 38 mixtures.
