7318.15.80.85 - Other

This HTS category, 7318.15.80.85, encompasses "Other" screws and bolts that do not fall into the preceding subcategories, specifically those with shanks or threads measuring 6 mm or more in diameter. These are threaded fasteners made of iron or steel, used to join materials together, but exclude those specifically classified elsewhere within the broader 7318.15.80 heading.

This classification is distinguished from its sibling category, 7318.15.80.82, by material composition. While 7318.15.80.82 is exclusively for fasteners manufactured from stainless steel, this category 7318.15.80.85 covers screws and bolts made from other iron or steel alloys that do not meet the criteria for stainless steel. The defining characteristic for both remains the shank or thread diameter of 6 mm or greater.

As this is a leaf node, there are no further subdivisions within this specific HTS code. Therefore, the focus is on correctly identifying screws and bolts of iron or steel, with a diameter of 6 mm or more, that are not of stainless steel and do not fit into any prior, more specific classifications within the broader heading. Examples could include certain types of carbon steel bolts or screws with specific plating or surface treatments not otherwise designated.
