7307.92.90.00 - Other

This HTS classification, 7307.92.90.00, specifically covers "Other" threaded fittings of iron or steel, excluding sleeves or couplings. These items are designed to join pipes or tubes, or to change the direction of flow within a piping system, through the use of threaded connections. Examples include threaded elbows, bends, and other specialized threaded fittings not otherwise specified.

This category is distinct from its sibling, 7307.92.30 ("Sleeves (couplings)"), which exclusively covers threaded pipe sleeves used for joining pipes end-to-end. While both are threaded fittings of iron or steel within the "Other" grouping, 7307.92.90.00 focuses on fittings that alter direction (bends, elbows) or serve different connection purposes beyond simple sleeve coupling.

As this is a leaf node within the HTS classification, there are no further subcategories. Classification under 7307.92.90.00 is determined by the item being a threaded fitting of iron or steel intended for piping systems, and not falling under the more specific descriptions of sleeves, couplings, or other enumerated categories within heading 73.07. The key determining factor is the presence of threads for connection and its function as a non-sleeve/coupling fitting.
