Cyclohexanecarboxylic Acid
Cyclohexanecarboxylic acid contains a saturated cyclohexane ring making it cycloaliphatic rather than acyclic, but sometimes misclassified. Actually belongs in 2916.20, shown here to illustrate common error vs true 2915.90.18.90 acyclic products.

Import Tips & Compliance
• Use NMR/GC to confirm acyclic vs cyclic structure for proper heading
• Cycloaliphatic acids require 2916 classification regardless of saturation
