1604.14.30.99 - Other

This classification, HTS Code 1604.14.30.99, encompasses prepared or preserved tuna and skipjack tuna, whole or in pieces, that are packed in airtight containers, not in oil, and do not fall into any other more specific subclassification. These products are typically canned or otherwise sealed in a manner that prevents the ingress of air and extends their shelf life. The "Other" designation signifies that these goods are not individually packaged in foil or other flexible containers weighing not more than 6.8 kg each, which is addressed by sibling category 1604.14.30.91.

The key differentiator for this subcategory is the absence of oil as a packing medium and the exclusion from flexible packaging. This means items like tuna packed in brine, water, or its own juices, but sealed in rigid cans or similar containers that do not meet the weight and material specifications of the sibling category, will be classified here. The focus remains on tuna and skipjack specifically, excluding other types of fish or preparations.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the classification hinges on meeting the conditions outlined by the parent categories and distinguishing the product from its direct sibling. Customs officers will examine the packaging type, the presence or absence of oil, and the specific species of fish to ensure accurate classification under this residual "Other" category for tuna and skipjack in airtight containers.
