1602.90 - Other, including preparations of blood of any animal:

This category, HTS 1602.90, encompasses a broad range of prepared or preserved meat products that do not fit into more specific subheadings within heading 1602. Crucially, it includes preparations made from the blood of any animal, regardless of its form or the method of preservation. This also extends to other miscellaneous meat preparations not otherwise specified, such as those made from insects or other invertebrates not covered by Chapter 16's primary scope.

Distinguishing 1602.90 from its sibling categories is key for accurate classification. Unlike 1602.10 which specifically covers homogenized preparations, or 1602.20 which is dedicated to liver preparations, this subheading captures those products lacking such specific processing or origin. Similarly, it differs from the more specific animal types covered under other 1602.xx codes, such as poultry (0105) or swine, by encompassing all other animal sources and unspecified meat preparations.

Within HTS 1602.90, further subdivisions exist to refine classification. The primary distinction is between frog meat preparations (1602.90.10.00) and all other types of preparations falling under this general category (1602.90.91). This highlights that while blood and miscellaneous preparations are grouped together, a specific type of meat preparation, namely frog meat, is given its own distinct sub-classification, necessitating careful review of the product's composition to determine the correct code.
