4407.99.02.42 - Hickory (Carya spp.) and pecan (Carya illinoensis, Carya pecan)

This HTS classification covers lumber of hickory (Carya spp.) and pecan (Carya illinoensis, Carya pecan) that has been sawn or chipped lengthwise, sliced, or peeled. The wood must also have a thickness exceeding 6 mm and may be further processed by planing, sanding, or end-jointing. This category specifically identifies these hardwoods, differentiating them from other wood species that may fall under the broader heading of "Other" within the lumber classification.

The distinction between this specific entry and its sibling categories lies in the precise wood species. For instance, while the sibling category 4407.99.02.61 pertains to walnut (Juglans spp) and 4407.99.02.63 to western red alder (Alnus rubra), this classification is exclusively for hickory and pecan. The sibling category 4407.99.02.95 encompasses "Other nonconiferous" wood, highlighting that hickory and pecan, as hardwoods, are not included in that general classification for softwoods.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification under 4407.99.02.42 is definitive once the material has been identified as lumber of hickory or pecan meeting the specified processing and thickness criteria. This level of specificity ensures accurate tariff application for these particular hardwood types.
