Heading 0906 covers both species without a species-level split at the HS4 level; the subheadings divide by form (whole bark, flowers, or crushed/ground) rather than by botanical species. However, FDA labeling rules require accurate species identification on the label, so importers must document the species regardless of tariff classification.

Yes. Whole cinnamon-tree flowers that are neither crushed nor ground fall under 090619, distinct from whole bark (090611). Once either is crushed or ground, both move to 090620, so processing stage is the key classification variable.
