Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If aromatic structure like phthalic acid
Aromatic polycarboxylic acids are classified earlier in heading 2917.11, but cyclanic goes to 2917.20 per numerical order rule.
If imported as a mixture with solvents for retail
Mixtures not qualifying as Chapter 29 preparations fall into Chapter 38 as chemical preparations.
If monocarboxylic rather than polycarboxylic
Cyclanic monocarboxylic acids are classified in heading 2902, not polycarboxylic acids of 2917.
