0601.10 - Bulbs, tubers, tuberous roots, corms, crowns and rhizomes, dormant:

Heading 0601.10 encompasses dormant bulbs, tubers, tuberous roots, corms, crowns, and rhizomes. These are vegetative propagation structures that are not yet actively growing or flowering. Their classification under this heading hinges on their dormant state, signifying their potential for future growth rather than their current horticultural display. This category serves as a foundational grouping for plant propagation material before it enters its active growth phase.

Distinguishing 0601.10 from its sibling, 0601.20, is critical. While both headings fall under the broader scope of Chapter 6 and deal with similar plant propagation materials, 0601.20 specifically covers those items that are "in growth or in flower." Therefore, the key differentiator is the physiological state of the plant material: dormant for 0601.10 and actively growing or flowering for 0601.20. Chicory plants and roots are also addressed in heading 0601, with dormant chicory roots falling under 0601.10 if they meet the criteria of being dormant.

Within the 0601.10 classification, further subdivisions exist to provide more granular detail on specific types of dormant propagation material. These subcategories, such as tulip bulbs (0601.10.15.00), hyacinth bulbs (0601.10.30.00), and lily bulbs (0601.10.45.00), recognize the distinct horticultural and commercial importance of common bulb types. The "Other" category (0601.10.90) is a residual provision for any dormant bulbs, tubers, corms, or rhizomes not specifically enumerated in the preceding subheadings, ensuring comprehensive coverage of all dormant propagation materials.
