0802.91.90.00 - Other

This HTS category, 0802.91.90.00, encompasses "Other" pine nuts that are in their shell. It falls under the broader classification of "Other nuts, fresh or dried, whether or not shelled or peeled" within Chapter 8 of the Harmonized Tariff Schedule. This designation is for pine nuts that do not fit into more specific subcategories for shelled or peeled varieties, and specifically for those still contained within their natural outer shell.

Within the immediate sibling categories, the primary distinction lies in the specificity of the product. While sibling category 0802.91.10.00 covers "Pignolia" pine nuts (often used interchangeably with pine nuts but sometimes referring to a specific species or market designation), this category, 0802.91.90.00, serves as a residual for any other types of pine nuts that remain in their shell, should they exist and be imported separately or in a less defined manner. The key classification criterion here is the presence of the shell and the fact that it is not a specifically enumerated or defined type of pine nut at the 10-digit level.

As this is a leaf node in the HTS structure, there are no further subcategories for 0802.91.90.00. Therefore, classification at this level requires careful consideration of the physical state of the pine nuts, confirming they are indeed in their shell and do not meet the specific criteria of any preceding, more granular HTS codes within the pine nut classification. This code acts as a catch-all for unshelled pine nuts that are not specifically identified as Pignolia.
