0703.10.40.64 - Yellow varieties, not marked sweet

This HTS classification, 0703.10.40.64, specifically covers yellow onions that are not marked as sweet. These are fresh or chilled onions primarily intended for consumption, and their defining characteristic is their yellow hue, coupled with a lack of inherent sweetness that would distinguish them from varieties specifically designated as sweet. This category falls under the broader grouping of onions and shallots within the alliaceous vegetables chapter.

It is crucial to distinguish this classification from its siblings. Unlike the red varieties (0703.10.40.55) or white varieties (0703.10.40.60), the defining color here is yellow. Furthermore, it differs from yellow varieties marked as sweet (0703.10.40.66), which are subject to a different tariff rate due to their specific sweet characteristic. The residual category, "Other" (0703.10.40.68), would encompass any yellow onions that do not fit the specific criteria of being either marked sweet or not marked sweet, which is unlikely given the direct differentiation provided.

As this classification represents a leaf node within the HTS structure, there are no further subcategories. This means that any product meeting the precise description of "Yellow varieties, not marked sweet" for onions will terminate at this HTS code. Therefore, classification hinges entirely on the physical attribute of color (yellow) and the absence of any explicit marking or inherent characteristic denoting sweetness.
