Import Tips & Compliance

Specify flake size and melting point range (132-135°C) in commercial invoice to distinguish from powder form

Include bulk density certification (0.6-0.8 g/cm³) as customs may verify physical specifications

Declare exact assay percentage; flakes below 98% purity risk reclassification as mixtures

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.

Pharmaceutical Grade Cinnamic Acid USP

USP-grade cinnamic acid meeting United States Pharmacopeia standards for purity and microbial limits, used as intermediate in drug synthesis. Classified under HTS 2916.39.06.00 as the pure aromatic monocarboxylic acid. Essential for APIs like cinnarizine and hydrocinnamic acid derivatives.

Cinnamic Acid 99% Powder

High-purity (99%) cinnamic acid powder for laboratory and fine chemical applications. This separate chemically defined organic compound fits HTS 2916.39.06.00 as an aromatic monocarboxylic acid. Used in research, flavor synthesis, and UV absorber production.

Industrial Cinnamic Acid Technical Grade

Technical grade cinnamic acid (95-98% purity) for large-scale industrial applications like resin production and polymer modification. Remains classified under HTS 2916.39.06.00 despite lower purity as it meets Chapter 29 definition of chemically defined compound. Cost-effective for bulk chemical processes.

Cinnamic Acid with Stabilizer

Cinnamic acid containing permitted stabilizer levels per Chapter Note (f) for preservation during transport. The added anticaking agent does not render it suitable for specific use beyond general chemical applications. Properly classified under HTS 2916.39.06.00 as stabilized pure compound.

alpha-Methylcinnamic Acid

Alpha-methylcinnamic acid, a substituted derivative of cinnamic acid maintaining the core phenylacrylic acid structure. Classified specifically under HTS 2916.39.06.00 as it chemically qualifies as cinnamic acid per tariff description. Used in specialty fragrance synthesis.
