0601 - Bulbs, tubers, tuberous roots, corms, crowns and rhizomes, dormant, in growth or in flower; chicory plants and roots other than roots of heading 1212:

Heading 0601 encompasses various forms of vegetative propagation material for plants, including bulbs, tubers, tuberous roots, corms, crowns, and rhizomes. These items are classified here regardless of their physiological state – whether dormant, actively growing, or even in bloom. Additionally, this heading covers chicory plants and their roots, provided they are not classified under heading 1212. The primary characteristic for classification within this heading is the plant's reproductive or vegetative structure intended for propagation.

This heading is distinct from preceding headings in Chapter 6, which focus on live trees and plants. While those headings deal with the living plant organism as a whole, 0601 specifically isolates the underground or basal storage and reproductive organs of plants, as well as specific plant types like chicory for their reproductive or root purposes. It also differentiates from other chapters by focusing on these specific vegetative propagation materials rather than finished horticultural products or raw plant materials for other uses.

Within heading 0601, further subdivision is made based on the state of development of the vegetative material. Subheading 0601.10 pertains to dormant bulbs, tubers, and similar structures, highlighting a state of rest. In contrast, subheading 0601.20 covers these same structures when they are actively in growth or in flower, indicating active vegetative development. This distinction allows for more precise classification based on the observable condition of the plant material.
