0304.91 - Swordfish (Xiphias gladius):

This HTS category, 0304.91, specifically covers frozen swordfish (Xiphias gladius) meat and fillets. It falls under the broader heading of other fish meat, whether or not minced, that is frozen. This means that any form of swordfish meat that has been frozen, including steaks, loins, or minced portions, will be classified here, provided it meets the criteria of being meat or fillets.

Distinguishing this category from its siblings is crucial for accurate classification. While other sibling categories at the 0304.9x level address specific types of frozen fish meat such as toothfish, tilapia, catfish, pollock, and various families of cod-like fish, 0304.91 is solely dedicated to swordfish. It is important not to misclassify swordfish under more general "other" fish categories if it is clearly identifiable as swordfish.

The subcategories within 0304.91 further refine the classification based on the packaging and presentation of the frozen swordfish meat. Subcategory 0304.91.10.00 applies to swordfish meat packed in bulk or in immediate containers weighing over 6.8 kg each, typically for wholesale or industrial processing. Conversely, subcategory 0304.91.90.00 encompasses all other presentations of frozen swordfish meat, which would include smaller retail-sized packaging or individual portions not meeting the weight threshold of the preceding subcategory.
