0705.11.20.00 - If entered in the period from June 1 to October 31, inclusive, in any year

This HTS classification, 0705.11.20.00, specifically covers head lettuce (also known as cabbage lettuce) when it is imported or exported during the period from June 1st to October 31st, inclusive, of any given year. This designation applies to fresh or chilled varieties of *Lactuca sativa* that are characterized by their tightly packed leaves forming a distinct head, similar in appearance to a cabbage.

This category is distinguished from its sibling category, 0705.11.40.00 ("Other"), by its specific seasonal restriction for entry. While both classifications pertain to head lettuce, the "Other" category would likely encompass head lettuce imported or exported outside of the June 1 to October 31 timeframe, or potentially other interpretations of head lettuce not explicitly covered by the seasonal rule.

As this is a leaf node, there are no further subcategories. The classification is finalized based on the product being head lettuce, fresh or chilled, and the specific import/export period stipulated in the description. Importers and exporters should verify that their goods meet the physical characteristics of head lettuce and that the customs entry falls within the defined seasonal window to ensure correct classification.
