Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If fluorene content exceeds 50% by weight
Fluorene classified specifically under 2902.90.30.00 takes precedence over the general 'other' category.
If petroleum-derived distillate mixture
Mixtures of hydrocarbons not meeting Chapter 29 purity criteria fall under Chapter 27 petroleum products.
If prepared chemical reaction mixture
Complex mixtures not qualifying as separate chemically defined compounds classified as chemical preparations.

Import Tips & Compliance
• Verify purity levels through Certificate of Analysis (CoA) as impurities may affect classification under Chapter 29 notes
• Ensure proper labeling as 'pure indene' vs mixtures to avoid reclassification to mixtures of isomers
• Obtain safety data sheets (SDS) for hazardous material declarations during customs clearance
