0705.11 - Head lettuce (cabbage lettuce):

This HTS category, 0705.11, specifically covers "Head lettuce (cabbage lettuce)" which refers to varieties of *Lactuca sativa* that form a compact head, such as iceberg lettuce. This classification is situated within Chapter 7 of the Harmonized Tariff Schedule, which deals with edible vegetables and certain roots and tubers. The defining characteristic for this subcategory is its specific growth habit and form, distinguishing it from other types of lettuce.

Within the broader classification of lettuce (0705.10), this category is differentiated from its sibling, 0705.19, which covers "Other" lettuce varieties. While 0705.11 is reserved for head lettuce, 0705.19 would encompass loose-leaf lettuce, romaine, or butterhead varieties that do not form a tight, cohesive head. Both classifications pertain to fresh or chilled lettuce.

The subcategories under 0705.11 provide further specificity based on the timing of entry. 0705.11.20.00 applies to head lettuce entered during the period of June 1 to October 31, inclusive, in any given year, likely reflecting seasonal trade considerations. The alternative, 0705.11.40.00, covers all other entries of head lettuce outside of this specified seasonal window.
