8309.90.00.85 - Other

This HTS category, 8309.90.00.85, encompasses "Other" packing accessories and parts thereof, of base metal, that are not specifically covered by other subdivisions within heading 8309. This heading broadly covers stoppers, caps, lids, capsules, bungs, and related items. Specifically, this residual category applies to base metal packing accessories whose material or specific construction does not align with more detailed classifications.

The primary distinction for this category lies in its exclusionary nature. It serves as a catch-all for items not classified under the more specific subheadings. For instance, while sibling category 8309.90.00.80 specifically covers items "Of steel," this category 8309.90.00.85 would apply to packing accessories made from other base metals such as aluminum, tin, copper, or zinc, or those with complex constructions not solely identifiable as steel.

As this is a leaf node, there are no further subcategories to introduce. Classification under this heading relies on a careful examination of the item's material composition, design, and intended function as a component for sealing or closing containers, ensuring it is not otherwise more precisely described by a preceding subheading within heading 8309.
