1604.20.15.00 - In oil

HTS code 1604.20.15.00 specifically classifies prepared or preserved fish that are presented in oil. This category encompasses a variety of fish products, such as fish balls, cakes, and puddings, which have undergone preparation and preservation processes and are packaged with oil. The presence of oil as a preserving or accompanying medium is the defining characteristic of this subheading.

This classification is distinguished from its sibling category, HTS 1604.20.11 (Other prepared or preserved fish: Other: Balls, cakes and puddings: Not in oil), by the method of preservation and presentation. While both subheadings cover fish balls, cakes, and puddings, the crucial differentiator is the absence of oil in the sibling category. Goods classified under 1604.20.15.00 will contain a discernible quantity of oil, either for preservation or as an integral part of the product's preparation.

As a leaf node, 1604.20.15.00 does not have further subcategories. Therefore, classification within this code relies directly on the determination that the prepared fish product, in the form of balls, cakes, or puddings, is indeed packed or prepared in oil. Customs officers will assess the product's presentation to confirm the presence and significance of oil in its packaging and composition, thereby ensuring accurate tariff application.
