0306.17.00.16 - Count size (headless weight) more than 154 per kg (70s)

This HTS category, 0306.17.00.16, specifically classifies frozen, shell-on shrimp and prawns that are farmed and imported under statistical note 1 to chapter 3. The defining characteristic of this classification is the count size, measured by headless weight, which is greater than 154 count per kilogram. This equates to a very small size, often referred to as "70s" or smaller.

The distinction between this subcategory and its siblings lies solely in the precise count size of the shrimp and prawns. Other sibling categories at this level delineate different size ranges, from larger counts like "15s" (less than 33 per kg) to intermediate sizes. This specific classification captures only the smallest commercially viable sizes within the farmed, frozen, shell-on shrimp and prawn category.

As this is a leaf node in the HTS classification, there are no further subdivisions. Therefore, the focus remains on the precise physical characteristic – the count size – that dictates its placement. Importers must ensure their product meets the "more than 154 per kg" headless weight criterion to correctly utilize this classification code.
