0703.90.00 - Leeks and other alliaceous vegetables

This HTS category, 0703.90.00, encompasses leeks and other alliaceous vegetables that are not specifically classified under onions, shallots, or garlic. It broadly covers vegetables belonging to the Allium genus, excluding those explicitly addressed in preceding subheadings. The focus here is on the distinct characteristics that differentiate these "other" alliaceous vegetables from their more commonly categorized counterparts.

Unlike the more specific subheadings for onions, shallots (0703.10), and garlic (0703.20.00), this category serves as a catch-all for remaining members of the Allium family. This includes, but is not limited to, items such as leeks, which possess a milder flavor and a different bulb structure compared to onions. It also includes other lesser-known alliums that do not fit the defined characteristics of the preceding sibling categories.

To further refine the classification within this broad group, two subcategories exist: 0703.90.00.20 for "Green onions of a species other than Allium cepa" and 0703.90.00.40 for "Other." This distinction acknowledges the specific morphology and botanical variations within the "other alliaceous vegetables" group, allowing for more precise tariff application. The "green onions" subheading addresses young, immature alliums often used for their leafy greens, while the "other" subheading captures any remaining leeks and alliaceous vegetables that do not meet the criteria for green onions.
