1604.13.40.00 - In immediate containers weighing with their contents under 225 grams each

This HTS category, 1604.13.40.00, specifically covers prepared or preserved fish, categorized as sardines, sardinella, or brisling/sprats. The defining characteristic for this subclassification is the weight of the immediate container and its contents, which must be under 225 grams. This includes a wide array of canned, pouched, or otherwise packaged small portions of these specific fish types, intended for direct consumption or further preparation.

This classification distinguishes itself from its sibling category, 1604.13.90.00, solely based on the container weight threshold. While both categories address sardines, sardinella, and brisling or sprats, the "Other" category encompasses products where the immediate container and its contents weigh 225 grams or more. Therefore, the critical differentiator is the size and packaging of the final consumer unit.

As this is a leaf node within the HTS structure, there are no further subcategories under 1604.13.40.00. This means that any product meeting the criteria of being sardines, sardinella, or brisling/sprats, prepared or preserved, and presented in immediate containers weighing with their contents under 225 grams, will be classified directly under this code. Examples might include small, single-serving cans or pouches of sardines in oil or tomato sauce, commonly found in retail grocery markets.
