0703.10.30.00 - Pearl onions not over 16 mm in diameter

This HTS classification, 0703.10.30.00, specifically pertains to pearl onions that have a diameter not exceeding 16 millimeters. These are typically small, whole onions, often distinguished by their size and mild flavor, commonly used in pickling, garnishes, or as whole cooked vegetables. The classification falls under the broader category of "Onions, shallots, garlic, leeks and other alliaceous vegetables, fresh or chilled."

Within the "Onions and shallots: Other" grouping, this subheading distinguishes itself from its sibling category, 0703.10.40, which covers "Other" onions and shallots not meeting the specific size criteria outlined here. Essentially, 0703.10.30.00 isolates the very small pearl onions, while 0703.10.40 would encompass larger onions or shallots that do not fit into more specific classifications.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification under this code is determined solely by the product being an onion and meeting the specific diameter requirement of not over 16 mm. This precise delimitation ensures accurate categorization for trade purposes, differentiating these specific pearl onions from other types of onions and shallots.
