Trans-Cinnamic Acid
Trans-cinnamic acid (C9H8O2) is the most common stereoisomer of cinnamic acid, an unsaturated aromatic monocarboxylic acid with a phenyl group attached to the acrylic acid moiety. It falls under HTS 2916.39.06.00 as a specific aromatic monocarboxylic acid derivative. Used primarily in organic synthesis and as a precursor for pharmaceuticals and fragrances.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If synthetic and containing >85% single isomer
High-purity synthetic cinnamic acid may qualify under the specific synthetic subheading rather than the general 'other' category.
If impure technical grade with significant non-cinnamic impurities
Mixtures not meeting Chapter 29 purity standards for separate chemically defined compounds classify as chemical preparations.
If classified primarily by alcohol function when esterified
Esters of cinnamic acid with simple alcohols may follow parent alcohol classification per Chapter Note ester rules.

Import Tips & Compliance
• Provide Certificate of Analysis confirming 99%+ purity and trans-isomer specification to avoid misclassification as technical grade
• Include Safety Data Sheet (SDS) documenting proper UN shipping name 'Cinnamic acid' for DOT compliance
• Verify supplier's REACH compliance documentation for EU-origin material to facilitate customs clearance
