1301.90.91.30 - Tragacanth

This HTS subcategory, 1301.90.91.30, specifically covers Tragacanth, a natural gum derived from the dried sap of various species of legumes belonging to the genus *Astragalus*. Tragacanth is characterized by its mucilaginous properties, forming a thick, viscous solution or gel when hydrated. It is primarily used as a thickening agent, emulsifier, and stabilizer in a wide range of products.

Distinguishing Tragacanth from its siblings involves recognizing its unique botanical origin and physical properties. While other entries under 1301.90.91 encompass balsams, shellac, seed lac, and karaya gum, Tragacanth is specifically identified as being from *Astragalus* plants. Unlike the hard resins found in some balsams or the exudates of the lac insect, Tragacanth is a pliable, translucent, or opaque gum. Its classification as "other" within the broader "other" category at this level emphasizes its distinct nature from more commonly listed gums and resins.

As this is a leaf node, there are no further subdivisions within this specific HTS code. Therefore, the focus remains on accurately identifying Tragacanth based on its source, chemical composition, and characteristic physical properties, ensuring it is not misclassified with other natural gums or resins that share some functional similarities but originate from different botanical sources or possess different physical attributes.
