Products classified under HTS 7307.99.50.45
Cast Iron Pipe Coupling
A threaded coupling fitting cast from gray iron, designed to join two plain-end pipes securely in drainage systems. Classified under HTS 7307.99.50.45 as an other tube or pipe fitting of iron or nonalloy steel. Ideal for underground sewer and stormwater applications.
Ductile Iron Flanged Reducer
A reducer fitting with flanged ends made from ductile (nodular) iron, connecting pipes of different diameters in water distribution. HTS 7307.99.50.45 covers this as other iron pipe fittings. Enhances flow transition in municipal systems.
Carbon Steel Threaded Pipe Union
Threaded union fitting from nonalloy carbon steel, allowing easy disconnection of pipe sections in maintenance-heavy lines. Under HTS 7307.99.50.45 for other iron/nonalloy fittings. Features ball-and-socket joint for alignment.
Welded Steel Pipe Cap
Threaded or weld end cap fitting from fabricated nonalloy steel sheet, sealing pipe ends in industrial piping. HTS 7307.99.50.45 applies to such other fittings. Prevents leakage in pressure systems.
malleable Iron Pipe Nipple
Short threaded nipple fitting from malleable iron, connecting close pipe sections in gas lines. Though malleable, falls in 7307.99.50.45 as other iron fittings if not socket type. Durable for low-pressure service.
Forged Steel Pipe Cross Fitting
Four-way cross fitting forged from nonalloy steel for multi-branch piping in process plants. HTS 7307.99.50.45 for other such fittings. High strength for demanding connections.
Black Iron Pipe Sleeve
Plain sleeve coupling from black iron (uncoated), used for repair/extension of piping. Other fitting under HTS 7307.99.50.45. Simple slip-fit design.
Nonalloy Steel Pipe Bend 45 Degree
45-degree long radius bend from nonalloy steel for smooth flow direction change in pipelines. Classed in HTS 7307.99.50.45 as other fitting. Induction bent construction.
Cast Steel Pipe Plug
