Ninhydrin Powder (1,2,3-Indantrione Monohydrate)
Pure 1,2,3-Indantrione monohydrate, commonly known as Ninhydrin, is an aromatic ketone-aldehyde used primarily as a reagent for detecting amino acids through color development. It falls under HTS 2914.40.2000 as a chemically defined aromatic ketone-alcohol/aldehyde per Chapter 29 notes. Typically supplied as a white to pale yellow crystalline powder for laboratory applications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pre-mixed as diagnostic reagent solution with solvents
Mixtures containing Ninhydrin for lab analysis fall under diagnostic reagents rather than pure organic compounds.
If sold as component in heterocyclic compound mixtures
When combined with other cyclic compounds beyond simple solutions, classification shifts to heterocyclic mixtures.
If incorporated into immunological or pharmaceutical preparations
Chapter 29 excludes immunological products; pharmaceutical grade formulations go to Chapter 30.

Import Tips & Compliance
• Provide chemical purity certificates (typically ≥98%) and CAS number (485-47-2) documentation to verify classification under Chapter 29
• Ensure proper Hazard Communication labeling as it’s a skin and eye irritant; include Safety Data Sheets (SDS) for customs clearance
• Avoid misclassification as a finished test kit—pure chemical only qualifies under this specific HTS code
