0704.90 - Other (including sprouting broccoli (Brassica oleracea var. italica)):

This HTS category, 0704.90, encompasses a range of edible brassicas that are not specifically classified under the preceding headings. While the description explicitly mentions sprouting broccoli (Brassica oleracea var. italica), its primary function is to act as a residual category for other members of the brassica family that do not fit into the more specific cauliflower and broccoli (0704.10) or Brussels sprouts (0704.20) classifications. This includes, but is not limited to, various types of kale and kohlrabi, fresh or chilled, that share the common characteristic of being leafy or stem vegetables within the Brassica genus.

The distinction from sibling categories is crucial for accurate classification. Unlike the cauliflower and broccoli (0704.10) which are defined by their distinct floral heads, and Brussels sprouts (0704.20) known for their small, bud-like structures, this category captures the more diverse forms of edible brassicas. This includes the leafy greens like kale, which are characterized by their dense, layered foliage, and kohlrabi, recognizable by its swollen, turnip-like stem.

The subcategories further refine this classification based on specific types of brassicas. 0704.90.20.00 is designated for cabbage, which comprises a broad range of cultivated varieties of Brassica oleracea, typically characterized by a compact, leafy head. The remaining "Other" category (0704.90.40) serves as a further residual for any other edible brassicas not otherwise specified, ensuring comprehensive coverage within Chapter 7 for this diverse group of vegetables.
