3301.29.51.07 - Of cassia

This HTS code, 3301.29.51.07, specifically classifies essential oils derived from cassia. Essential oils are concentrated hydrophobic liquids containing volatile chemical compounds from plants. These oils are typically obtained through distillation or mechanical methods, capturing the characteristic aroma and flavor of the source material. In this instance, the "cassia" refers to oils extracted from the bark, leaves, or other parts of plants belonging to the *Cinnamomum* genus, commonly known as cinnamon, but distinct from true cinnamon (*Cinnamomum verum*).

This category is distinguished from its siblings by the specific botanical origin of the essential oil. For example, while 3301.29.51.03 covers oils of anise and 3301.29.51.05 covers oils of caraway, this classification is exclusively for oils derived from cassia. The unique aromatic profile and chemical composition of cassia oil set it apart for classification purposes, often used in food flavoring, perfumery, and aromatherapy.

As this classification represents a leaf node within the HTS, there are no further subcategories. Therefore, the primary focus for classification under this code is the accurate identification of the oil as being derived from cassia, ensuring it is not confused with other spices or botanical sources that fall under different HTS codes within the broader category of "Essential oils other than those of citrus fruit: Other: Other."
