Forged Alloy Steel Pipe Coupling 2-inch NPT from Japan

A threaded sleeve coupling made from low-alloy steel like AISI 4140, designed to join two 2-inch nominal pipe size threaded pipes end-to-end. It falls under HTS 7307.92.3030 as a threaded sleeve of alloy steel (not stainless), used in high-pressure plumbing and industrial piping systems. The alloy composition provides enhanced strength and corrosion resistance compared to carbon steel.

Import Tips

Verify alloy steel composition via mill test certificate to confirm exclusion of stainless steel and qualify under this subheading

Include detailed technical specs like pressure rating and thread standard (NPT/BSP) in commercial invoice to avoid misclassification as unthreaded fittings
